+/*! @file ErasureCodeInterface.h
+ @brief Interface provided by erasure code plugins
+
+ The erasure coded pools rely on plugins implementing
+ **ErasureCodeInterface** to encode and decode content. All codes
+ are systematic (i.e. the data is not mangled and can be
+ reconstructed by concatenating chunks ).
+
+ Methods returning an **int** return **0** on success and a
+ negative value on error. If the value returned on error is not
+ explained in **ErasureCodeInterface**, the sources or the
+ documentation of the interface implementer (i.e. the plugin ) must
+ be read to figure out what it means. It is recommended that each
+ error code matches an *errno* value that relates to the cause of
+ the error.
+
+ If an object is small enough, the caller can process it with
+ one call to the **encode** or **decode** method.
+
+ +---------------- coded object O -------------------------+
+ |+----------------+ +----------------+ +----------------+ |
+ || chunk 0 | | chunk 1 | | chunk 2 | |
+ || [0,N) | | [N,2N) | | [2N,3N) | |
+ |+----------------+ +----------------+ +----------------+ |
+ +------^--------------------------------------------------+
+ |
+ chunk B / C | offset B % C ( where C is the chunk size )
+ |
+ +-----^---- raw object O ----+------+
+ | B [0,X) | pad |
+ +----------------------------+------+
+
+ The object size is paded so that each chunks are of the same size.
+ In the example above, if the actual object size was X, then it
+ will be padded to 2N >= X assuming there are two data chunks (0
+ and 1) and one coding chunk (2).
+
+ For chunks of size C, byte B of the object is found in chunk number
+ B / C at offset B % C.
+
+ If an object is too large to be encoded in memory, the caller
+ should divide it in smaller units named **stripes**.
+
+ +---------------------- object O -------------------------+
+ |+----------------+ +----------------+ +----------------+ |
+ stripe || chunk 0 | | chunk 1 | | chunk 2 | |
+ 0 || [0,N) | | [N,2N) | | [2N,3N) | |
+ |+----------------+ +----------------+ +----------------+ |
+ |+----------------+ +----------------+ +----------------+ |
+ stripe || chunk 0 | | chunk 1 | | chunk 2 | |
+ 1 || [X,M) | | [X+M,X+2M) | | [X+2M,X+3M) | |
+ || | | | | | |
+ |+----------------+ +----------------+ +----------------+ |
+ | ... |
+ +---------------------------------------------------------+
+
+ The interface does not concern itself with stripes nor does it
+ impose constraints on the size of each stripe. Variable names in
+ the interface always use **object** and never use **stripe**.
+
+ Assuming the interface implementer provides three data chunks ( K
+ = 3 ) and two coding chunks ( M = 2 ), a buffer could be encoded as
+ follows:
+
+ ~~~~~~~~~~~~~~~~{.c}
+ set<int> want_to_encode(0, 1, 2, // data chunks
+ 3, 4 // coding chunks
+ );
+ bufferlist in = "ABCDEF";
+ map<int, bufferlist> encoded
+ encode(want_to_encode, in, &encoded);
+ encoded[0] == "AB" // data chunk 0
+ encoded[1] == "CD" // data chunk 1
+ encoded[2] == "EF" // data chunk 2
+ encoded[3] // coding chunk 0
+ encoded[4] // coding chunk 1
+ ~~~~~~~~~~~~~~~~
+
+ The **minimum_to_decode_with_cost** method can be used to minimize
+ the cost of fetching the chunks necessary to retrieve a given
+ content. For instance, if encoded[2] (contained **EF**) is missing
+ and accessing encoded[3] (the first coding chunk) is more
+ expensive than accessing encoded[4] (the second coding chunk),
+ **minimum_to_decode_with_cost** is expected to chose the first
+ coding chunk.
+
+ ~~~~~~~~~~~~~~~~{.c}
+ set<int> want_to_read(2); // want the chunk containing "EF"
+ map<int,int> available(
+ 0 => 1, // data chunk 0 : available and costs 1
+ 1 => 1, // data chunk 1 : available and costs 1
+ // data chunk 2 : missing
+ 3 => 9, // coding chunk 1 : available and costs 9
+ 4 => 1, // coding chunk 2 : available and costs 1
+ );
+ set<int> minimum;
+ minimum_to_decode_with_cost(want_to_read,
+ available,
+ &minimum);
+ minimum == set<int>(0, 1, 4); // NOT set<int>(0, 1, 3);
+ ~~~~~~~~~~~~~~~~
+
+ It sets **minimum** with three chunks to reconstruct the desired
+ data chunk and will pick the second coding chunk ( 4 ) because it
+ is less expensive ( 1 < 9 ) to retrieve than the first coding
+ chunk ( 3 ). The caller is responsible for retrieving the chunks
+ and call **decode** to reconstruct the second data chunk.
+
+ ~~~~~~~~~~~~~~~~{.c}
+ map<int,bufferlist> chunks;
+ for i in minimum.keys():
+ chunks[i] = fetch_chunk(i); // get chunk from storage
+ map<int, bufferlist> decoded;
+ decode(want_to_read, chunks, &decoded);
+ decoded[2] == "EF"
+ ~~~~~~~~~~~~~~~~
+
+ The semantic of the cost value is defined by the caller and must
+ be known to the implementer. For instance, it may be more
+ expensive to retrieve two chunks with cost 1 + 9 = 10 than two
+ chunks with cost 6 + 6 = 12.

+============================================
+INTEL ISA library Erasure Coding plugin
+============================================
+
+Build Requirements
+==================
+Plug-in build compiles the included sources of ISA-L v2.10 and links them into the plugin. ISA-L implementation is portable and probes CPU features during runtime. Note that the names of the assembler source files have been renamed from *.asm to *.asm.s to be compatible with Automake.
+
+Run-time Requirements
+=====================
+None
+
+Plug-in Configuration
+=====================
+
+Used parameters are:
+k : number of data chunks
+m : number of coding chunks
+technique : cauchy, reed_sol_van
+
+The plug-in exports only two encoding technique (cauchy, reed_sol_van) using either a Vandermonde matrix or a Cauchy matrix for coding.
+By default a Vandermonde matrix is used. Be aware that sometimes the generated Vandermonde matrix is not always invertible and not fully MDS.
+Therefore the accepted parameter space has limited to maximum (21,4) and (32,3) for Vandermonde matrices.
+
+Run the Test suite
+==================
+cd ceph/src
+make unittest_erasure_code_isa
+./unittest_erasure_code_isa --gtest_filter=*.* --log-to-stderr=true --debug-ods=20
+
+Run the CEPH erasure code benchmark
+===================================
+cd ceph/src
+make ceph_erasure_code_benchmark
+
+# consult ./ceph_erasure_code_benchmark -h for help
+
+# encode performance
+./ceph_erasure_code_benchmark -p isa -P k=8 -P m=3 -S 1048576 -i 1000
+
+# decode performance one lost
+./ceph_erasure_code_benchmark -e 1 -w decode -p isa -P k=8 -P m=3 -S 1048576 -i 1000
+
+# decode performance two lost
+./ceph_erasure_code_benchmark -e 2 -w decode -p isa -P k=8 -P m=3 -S 1048576 -i 1000
+
+# decode performance three lost
+./ceph_erasure_code_benchmark -e 3 -w decode -p isa -P k=8 -P m=3 -S 1048576 -i 1000
+
+
+Developer Notes
+===============
+The plugin provides optimal performance for 32-byte aligned buffer start address and
+k*32 byte aligned buffer length. The encoding tables are computed only once when the EC
+object is created. Decoding Tables have to be computed for each decoding since the available
+data/coding sources may change between calls.
+Decoding tables are cached in an LRU cache which is sufficiently large up to (12,4).
+
+For larger configurations the cache might expire the 'oldest' tables and decoding might
+slow down. The plug-in uses an optimization to use a pure region XOR to decode single disk
+failures if the erased chunk is within the first (k+1) chunks.
+
+The unittest probes all possible failure scenarios for (12,4) Vandermonde and Cauchy matrices.

+#
+# SYNOPSIS
+#
+# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
+#
+# DESCRIPTION
+#
+# Check whether the given FLAG works with the current language's compiler
+# or gives an error. (Warnings, however, are ignored)
+#
+# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
+# success/failure.
+#
+# If EXTRA-FLAGS is defined, it is added to the current language's default
+# flags (e.g. CFLAGS) when the check is done. The check is thus made with
+# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
+# force the compiler to issue an error when a bad flag is given.
+#
+# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
+# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

+This is a user's manual for GF-Complete, version 1.02. This release supersedes version 0.1 and represents the first
+major release of GF-Complete. To our knowledge, this library implements every Galois Field multiplication technique
+applicable to erasure coding for storage, which is why we named it GF-Complete. The primary goal of this library is
+to allow storage system researchers and implementors to utilize very fast Galois Field arithmetic for Reed-Solomon
+coding and the like in their storage installations. The secondary goal is to allow those who want to explore different
+ways to perform Galois Field arithmetic to be able to do so effectively.
+
+

+<h2>If You Use This Library or Document </h2>
+
+
+
+Please send me an email to let me know how it goes. Or send me an email just to let me know you are using the
+library. One of the ways in which we are evaluated both internally and externally is by the impact of our work, and if
+you have found this library and/or this document useful, we would like to be able to document it. Please send mail to
+<em>plank@cs.utk.edu.</em> Please send bug reports to that address as well.

+<b>Finding the Code </b>
+<br><br>
+This code is actively maintained on bitbucket:<a href=""> https://bitbucket.org/jimplank/gf-complete. </a> There are
+previous versions on my UTK site as a technical report; however, that it too hard to maintain, so the main version is
+on bitbucket.<br><br>
+
+
+<b>Two Related Papers </b> <br><br>
+
+This software acccompanies a large paper that describes these implementation techniques in detail [PGM13a]. We
+will refer to this as <em> "The Paper." </em> You do not have to read The Paper to use the software. However, if you want to
+start exploring the various implementations, then The Paper is where you'll want to go to learn about the techniques
+in detail.
+
+
+
+<p>This library implements the techniques described in the paper "Screaming Fast Galois Field Arithmetic Using Intel
+SIMD Instructions," [PGM13b]. The Paper describes all of those techniques as well.

+Please contact the first author of this manual.<br><br>
+
+<b>Changes from Revision 1.01</b>
+<br><br>
+The major change is that we are using autoconf to aid with compilation, thus obviating the need for the old <b>flag_tester</b>
+code. Additionally, we have added a quick timing tool, and we have modified <b>gf_methods</b> so that it may be used to
+run the timing tool and the unit tester.

+<h3>1 Introduction </h3>
+
+Galois Field arithmetic forms the backbone of erasure-coded storage systems, most famously the Reed-Solomon
+erasure code. A Galois Field is defined over w-bit words and is termed <em>GF(2<sup>w</sup>).</em> As such, the elements of a Galois
+Field are the integers 0, 1, . . ., 2<sup>w</sup> - 1. Galois Field arithmetic defines addition and multiplication over these closed
+sets of integers in such a way that they work as you would hope they would work. Specifically, every number has a
+unique multiplicative inverse. Moreover, there is a value, typically the value 2, which has the property that you can
+enumerate all of the non-zero elements of the field by taking that value to successively higher powers.
+
+
+<p>Addition in a Galois Field is equal to the bitwise exclusive-or operation. That's nice and convenient. Multiplication
+is a little more complex, and there are many, many ways to implement it. The Paper describes them all, and the
+following references providemore supporting material: [Anv09, GMS08, LHy08, LD00, LBOX12, Pla97]. The intent
+of this library is to implement all of the techniques. That way, their performancemay be compared, and their tradeoffs
+may be analyzed. <p>
+
+
+
+
+<ol>
+
+When used for erasure codes, there are typically five important operations:<br>
+<li> <b>Adding two numbers in </b> GF(2<sup>w</sup>). That's bitwise exclusive-or. </li>
+<li> <b>Multiplying two numbers in</b> GF(2<sup>w</sup>). Erasure codes are usually based on matrices in GF(2<sup>w</sup>), and constructing
+these matrices requires both addition and multiplication.</li>
+<li> <b>Dividing two numbers in </b>GF(2<sup>w</sup>). Sometimes you need to divide to construct matrices (for example, Cauchy
+Reed-Solomon codes [BKK<sup>+</sup>95, Rab89]). More often, though, you use division to invert matrices for decoding.
+Sometimes it is easier to find a number's inverse than it is to divide. In that case, you can divide by multiplying
+by an inverse. </li>
+
+<li><b>adding two regions of numbers in</b> GF(2<sup>w</sup>), which will be explained along with... </li>
+<li> <b>Mutiplying a region of numbers in </b>GF(2<sup>w</sup>) by a constant in GF(2<sup>w</sup>). Erasure coding typically boils down
+to performing dot products in GF(2<sup>w</sup>). For example, you may define a coding disk using the equation: </li><br>
+
+
+
+
+<center>c<em><sub>0</sub></em>= d<em><sub>0</sub></em> + 2d<em><sub>1</sub></em> + 4d<em><sub>2</sub></em> + 8d<em><sub>3</sub></em>.</sup> </center><br>
+
+That looks like three multiplications and three additions However, the way ' implemented in a disk system
+looks as in Figure 1. Large regions of disks are partitioned into w-bit words in GF(2<sup>w</sup>). In the example, let us
+suppose that <em>w</em> = 8, and therefore that words are bytes. Then the regions pictured are 1 KB from each disk.
+The bytes on disk Di are labeled d<sub>i,0,</sub> d<sub>i,1, . . . ,</sub> d<sub>i,1023,</sub> and the equation above is replicated 1024 times. For
+0 &#8804 j < 1024:
+<br><br>
+<center>c<em><sub>0,j</sub></em> = d<em><sub>0,j</sub></em> + 2d<em><sub>1,j</sub></em> + 4d<em><sub>2,j</sub></em> + 8d<em><sub>3,j</sub></em> . </center>
+<br>
+
+
+While it's possible to implement each of these 1024 equations independently, using the single multiplication
+and addition operations above, it is often much more efficient to aggregate. For example, most computer architectures
+support bitwise exclusive-or of 64 and 128 bit words. Thus, it makes much more sense to add regions
+of numbers in 64 or 128 bit chunks rather than as words in GF(2<sup>w</sup>). Multiplying a region by a constant can
+leverage similar optimizations. </ol>
+
+
+<p>GF-Complete supports multiplication and division of single values for all values of <em>w</em> &#8804 32, plus <em>w</em> = 64 and <em>w</em> =
+128. It also supports adding two regions of memory (for any value of <em>w</em>, since addition equals XOR), and multiplying
+a region by a constant in <em>GF(2<sup>4</sup>), GF(2<sup>8</sup>), GF(2<sup>16</sup>), GF(2<sup>32</sup>), GF(2<sup>64</sup>) and GF(2<sup>128</sup>).</em> These values are chosen
+because words in GF(2<sup>w</sup>) fit into machine words with these values of <em>w.</em> Other values of w don't lend themselves
+to efficient multiplication of regions by constants (although see the <b>"CAUCHY"</b> option in section 6.1.5 for a way to
+multiply regions for other values of <em>w</em>).</p>

+Figure 1: An example of adding two regions of numbers, and multiplying a region of numbers by a constant
+in <em>GF(2<sup>w</sup>) </em>. In this example, <em>w</em> = 8, and each disk is holding a 1KB region. The same coding equation -
+c<sub>0,j</sub></b> = d<sub>0,j</sub> + ad<sub>1,j</sub> + a<sup>2</sup>d<sub>2,j</sub> + a<sup>3</sup>d<sub>3,j</sub> is applied 1024 times. However, rather than executing this equation 1024
+times, it is more efficient to implement this with three region-constant multiplications and three region-region additions.
+
+<h3>2 &nbsp&nbsp&nbsp Files in the Library </h3>
+This section provides an overview of the files that compose GF-Complete. They are partitioned among multiple
+directories.
+
+<h4> <b>2.1 &nbsp&nbsp&nbsp Header files in the directory "include"</b> </h4>
+
+The following header files are part of GF-Complete.
+<ul>
+<li><b>gf_complete.h:</b> This is the header file that applications should include. It defines the gf_t type, which holds
+all of the data that you need to perform the various operations in GF(2<sup>w</sup>). It also defines all of the arithmetic
+operations. For an application to use this library, you should include gf_complete.h and then compile with the
+library src/libgf_complete.la. </li><br>
+
+<li><b>gf_method.h:</b> If you are wanting to modify the implementation techniques from the defaults, this file provides
+a "helper" function so that you can do it from the Unix command line.
+</li><br>
+
+<li><b>gf_general.h:</b> This file has helper routines for doing basic Galois Field operations with any legal value of <em>w.</em>
+The problem is that <em>w </em> &#8804 32, <em>w </em> = 64 and <em> w </em> = 128 all have different data types, which is a pain. The procedures
+in this file try to alleviate that pain. They are used in <b>gf_mult, gf_unit</b> and <b>gf_time.</b> I'm guessing that most
+applications won't use them, as most applications use <em>w</em> &#8804 32. </li><br>
+
+<li><b>gf_rand.h:</b> I've learned that <b>srand48()</b> and its kin are not supported in all C installations. Therefore, this file
+defines some randomnumber generators to help test the programs. The randomnumber generator is the "Mother
+</li>
+
+</ul>
+
+

+of All" random number generator [Mar94] which we've selected because it has no patent issues. <b>gf_unit</b> and
+<b>gf_time</b> use these random number generators.<br><br>
+<li><b>gf_int.h:</b> This is an internal header file that the various source files use. This is <em>not</em> intended for applications to
+include.</li><br>
+<li><b>config.xx</b> and <b>stamp-h1</b> are created by autoconf, and should be ignored by applications. </li>
+</ul>
+
+<h3>2.2 &nbsp &nbsp <b> Source files in the "src" directory" </b> </h3>
+<ul>
+The following C files compose <b>gf_complete.a,</b> and they are in the direcoty src. You shouldn't have to mess with these
+files, but we include them in case you have to:<br><br>
+<li><b> gf_.c:</b> This implements all of the procedures in both <b>gf_complete.h</b> and <b>gf_int.h.</b> </li><br>
+<li><b> gf_w4.c:</b> Procedures specific to <em>w </em> = 4. </li><br>
+<li> <b>gf_w8.c:</b> Procedures specific to <em>w </em> = 8</li><br>
+<li> <b>gf_w16.c:</b> Procedures specific to <em>w </em> = 16</li><br>
+<li> <b>gf_w32.c:</b> Procedures specific to <em>w </em> = 32</li><br>
+<li><b>gf_w64.c:</b> Procedures specific to <em>w </em> = 64</li><br>
+<li> <b>gf_w128.c:</b> Procedures specific to <em>w </em> = 128</li><br>
+<li> <b>gf_wgen.c:</b> Procedures specific to other values of <em>w </em> between 1 and 31</li><br>
+<li> <b>gf_general.c:</b> Procedures that let you manipulate general values, regardless of whether <em>w </em> &#8804 32, <em>w </em> = 64
+or <em>w </em> = 128. (I.e. the procedures defined in <b>gf_ general.h</b>)</li><br>
+<li> <b>gf_method.c:</b> Procedures to help you switch between the various implementation techniques. (I.e. the procedures
+defined in <b>gf_method.h</b>)</li><br>
+<li> <b>gf_ rand.c:</b>"The Mother of all" random number generator. (I.e. the procedures defined in <b>gf_rand.h</b>)</li><br> </ul>
+
+<h3>2.3 &nbsp &nbsp Library tools files in the "tools" directory </h3>
+
+<ul>
+The following are tools to help you with Galois Field arithmetic, and with the library. They are explained in greater
+detail elsewhere in this manual.<br><br>
+<li> <b>gf_mult.c, gf_ div.c</b> and <b>gf_ add:</b> Command line tools to do multiplication, division and addition by single numbers</li><br>
+<li> <b>gf_time.c:</b> A program that times the procedures for given values of <em>w </em> and implementation options</li><br>
+<li> <b>time_tool.sh:</b> A shell script that helps perform rough timings of the various multiplication, division and region
+operations in GF-Complete</li><br>
+<li> <b>gf_methods.c:</b> A program that enumerates most of the implementation methods supported by GF-Complete</li><br>
+<li> <b> gf_poly.c:</b> A program to identify irreducible polynomials in regular and composite Galois Fields</li><br>

+
+
+<h3>2.4 &nbsp &nbsp The unit tester in the "test" directory </h3>
+
+The test directory contains the proram <b>gf_unit.c,</b> which performs a battery of unit tests on GF-Complete. This is
+explained in more detail in section 6.3.
+
+
+<h3>2.5&nbsp &nbsp Example programs in the "examples" directory </h3>
+
+There are seven example programs to help you understand various facets of GF-Complete. They are in the files
+<b>gf_example x.c </b> in the <b>examples</b> directory. They are explained in sections 4.2 through 4.5, and section 7.9.<br><br>
+
+<h2>3 &nbsp &nbsp Compilation </h2>
+
+<em>From revision 1.02 forward, we are using autoconf. The old "flag tester" directory is now gone, as it is no longer in
+use. </em><br><br>
+To compile and install, you should do the standard operations that you do with most open source Unix code:<br><br>
+
+UNIX> ./configure <br>
+... <br>
+UNIX> make <br>
+... <br>
+UNIX> sudo make install <br><br>
+
+
+<p>If you perform the <b>install,</b> then the header, source, tool, and library files will be moved to system locations. In
+particular, you may then compile the library by linking with the flag <b>-lgf_complete,</b> and you may use the tools from a
+global executable directory (like <b>/usr/local/bin</b>). </p>
+
+<p>
+If you don't perform the install, then the header and tool files will be in their respective directories, and the library
+will be in <b>src/libgf_complete.la.</b> </p>
+<p>
+If your system supports the various Intel SIMD instructions, the compiler will find them, and GF-Complete will
+use them by default. </p>
+

+<h2>4 &nbsp &nbsp Some Tools and Examples to Get You Started </h2>
+<h3>4.1 Three Simple Command Line Tools: gf_mult, gf_div and gf_add </h3>
+
+
+Before delving into the library, it may be helpful to explore Galois Field arithmetic with the command line tools:
+<b>gf_mult, gf_div </b> and <b>gf_add.</b> These perform multiplication, division and addition on elements in <em>GF(2<sup>w</sup>).</em> If these are
+not installed on your system, then you may find them in the tools directory. Their syntax is:
+<ul>
+<li><b>gf_mult a b</b> <em>w </em> - Multiplies a and b in <em> GF(2<sup>w</sup>)</em>. </li><br>
+<li> <b>gf_div a b </b><em>w </em> - Divides a by b in GF(2<em><sup>w </sup></em>). </li><br>
+<li><b>gf_add a b </b> <em>w </em> - Adds a and b in GF(2<em><sup>w </sup> </em>). </li><br>
+
+You may use any value of <em>w </em> from 1 to 32, plus 64 and 128. By default, the values are read and printed in decimal;
+however, if you append an 'h' to <em>w </em>, then <em>a, b </em> and the result will be printed in hexadecimal. For <em>w </em> = 128, the 'h' is
+mandatory, and all values will be printed in hexadecimal.

+Don't bother trying to read the source code of these programs yet. Start with some simpler examples like the ones
+below. <br><br>
+
+<h3>4.2 Quick Starting Example #1: Simple multiplication and division </h3>
+
+The source files for these examples are in the examples directory.
+<p>These two examples are intended for those who just want to use the library without getting too complex. The
+first example is <b>gf_example 1,</b> and it takes one command line argument - w, which must be between 1 and 32. It
+generates two random non-zero numbers in <em>GF(2<sup>w </sup>) </em> and multiplies them. After doing that, it divides the product by
+each number. </p>
+<p>
+To perform multiplication and division in <em>GF(2<sup>w </sup>) </em>, you must declare an instance of the gf_t type, and then initialize
+it for <em>GF(2<sup>w </sup>) </em> by calling <b>gf_init_easy().</b> This is done in <b>gf_example 1.c</b> with the following lines: </p><br><br>
+
+gf_t gf; <br><br>r
+... <br><br>
+if (!gf_init_easy(&gf, w)) { <br>
+fprintf(stderr, "Couldn't initialize GF structure.\n"); <br>

+
+<p>Once <b>gf</b> is initialized, you may use it for multiplication and division with the function pointers <b>multiply.w32</b> and
+<b>divide.w32.</b> These work for any element of <em>GF(2<sup>w</sup>)</em> so long as w &#8804 32. </p> <br><br>

+
+
+
+<h3>4.3 &nbsp &nbsp &nbspQuick Starting Example #2: Multiplying a region by a constant </h3>
+
+
+The program <b>gf_example</b> 2 expands on <b>gf_example</b> 1. If <em>w</em> is equal to 4, 8, 16 or 32, it performs a region multiply
+operation. It allocates two sixteen byte regions, <b>r1</b> and <b>r2,</b> and then multiples <b>r1</b> by a and puts the result in <b>r2</b> using
+the <b>multiply_region.w32</b> function pointer: <br><br>
+
+<div style="padding-left:52px">
+gf.multiply_region.w32 (&gf, r1, r2, a, 16, 0); <br><br>
+</div>
+
+That last argument specifies whether to simply place the product into r2 or to XOR it with the contents that are already
+in r2. Zero means to place the product there. When we run it, it prints the results of the <b>multiply_region.w32</b> in
+hexadecimal. Again, you can verify it using <b>gf_mult</b>:<br><br>

+
+<h2>5 &nbsp &nbsp &nbspImportant Information on Alignment when Multiplying Regions </h2>
+
+
+
+In order to make multiplication of regions fast, we often employ 64 and 128 bit instructions. This has ramifications
+for pointer alignment, because we want to avoid bus errors, and because on many machines, loading and manipulating
+aligned quantities is much faster than unalinged quantities.<br><br>
+
+
+When you perform multiply_region.wxx(<em>gf, source, dest, value, size, add </em>), there are three requirements:
+<ol>
+<li>
+ The pointers <em>source</em> and <em>dest </em> must be aligned for <em>w</em>-bit words. For <em>w </em> = 4 and <em>w </em> = 8, there is no restriction;
+however for <em>w </em> = 16, the pointers must be multiples of 2, for <em>w </em> = 32, they must be multiples of 4, and for
+<em>w </em> &#1013; {64, 128}, they must be multiples of 8. </li><br>
+
+<li> The <em>size</em> must be a multiple of &#91; <em>w /
+</em>
+8 .&#93;
+ With <em>w </em> = 4 and <em>w </em> = 8, <em>w/ </em>
+8 = 1 and there is no restriction. The other
+sizes must be multiples of <em>w </em>/
+8 because you have to be multiplying whole elements of <em> GF(2<sup>w </sup>) </em>. </li><br>
+
+<li> The <b>source</b> and <b>dest</b> pointers must be aligned identically with respect to each other for the implementation
+chosen. This is subtle, and we explain it in detail in the next few paragraphs. However, if you'd rather not figure
+it out, the following recommendation will <em>always </em> work in GF-Complete: </li>
+
+</ol>
+
+
+
+<div style="padding-left:100px">
+<b>If you want to be safe, make sure that source and dest are both multiples of 16. That is not a
+strict requirement, but it will always work! </b> <br><br>
+</div>
+
+
+If you want to relax the above recommendation, please read further.
+<p>When performing <b>multiply_region.wxx() </b>, the implementation is typically optimized for a region of bytes whose
+size must be a multiple of a variable <em>s </em> ,, and which must be aligned to a multiple of another variable <em>t </em>. For example,
+when doing <b>multiply_region.w32() </b> in <em> GF(2<sup>16 </sup>) </em> with SSE enabled, the implementation is optimized for regions of
+32 bytes, which must be aligned on a 16-byte quantity. Thus, <em>s </em> = 32 and <em>t</em> = 16. However, we don't want <b>multiply_
+region.w32() </b> to be too restrictive, so instead of requiring <em>source</em> and <em> dest </em> to be aligned to 16-byte regions, we
+require that (<em>source </em> mod 16) equal (<em>dest</em> mod 16). Or, in general, that (<em>source</em> mod t) equal (<em>dest</em> mod <em>t</em>). </p>
+
+
+<p>
+Then, <b>multiply_region.wxx()</b> proceeds in three phases. In the first phase,<b> multiply.wxx()</b> is called on successive
+words until (<em>source</em> mod <em>t</em>) equals zero. The second phase then performs the optimized region multiplication on
+chunks of <em> s </em>bytes, until the remaining part of the region is less than s bytes. At that point, the third phase calls
+<em>multiply.wxx() </em> on the last part of the region. </p>
+
+A detailed example helps to illustrate. Suppose we make the following call in <em>GF(2<sup>16</sup>) </em> with SSE enabled:<br><br>
+<center><b>multiply region.w32(gf, 0x10006, 0x20006, a, 274, 0)</b> </center>

+
+Figure 2: Example of multiplying a region of 274 bytes in GF(216) when (source mod 16) = (dest mod 16) = 6. The
+alignment parameters are s = 32 and t = 16. The multiplication is in three phases, which correspond to the initial
+unaligned region (10 bytes), the aligned region of s-byte chunks (256 bytes), and the final leftover region (8 bytes).
+
+
+<p>First, note that <em>source</em> and <em>dest</em> are aligned on two-byte quantities, which they must be in <em>GF(2<sup>16</sup>).</em> Second, note
+that size is a multiple of &#91; 16/
+8 &#93 = 2. And last, note that (<em>source</em> mod 16) equals (<em>dest</em> mod 16). We illustrate the three
+phases of region multiplication in Figure 2. Because (<em>source</em> mod 16) = 6, there are 10 bytes of unaligned words that
+are multiplied with five calls to <b>multiply.w32()</b> in the first phase. The second phase multiplies 256 bytes (eight chunks
+of <em>s</em> = 32 bytes) using the SSE instructions. That leaves 8 bytes remaining for the third phase.
+</p>
+
+<p>
+When we describe the defaults and the various implementation options, we specify s and t as "alignment parameters."
+</p>
+<p>
+One of the advanced region options is using an alternate mapping of words to memory ("ALTMAP"). These interact
+in a more subtle manner with alignment. Please see Section 7.9 for details.
+</p>
+
+<h3> 6 &nbsp &nbspThe Defaults </h3>
+
+
+GF-Complete implements a wide variety of techniques for multiplication, division and region multiplication. We have
+set the defaults with three considerations in mind:
+<ol>
+<li>
+<b>Speed:</b> Obviously, we want the implementations to be fast. Therefore, we choose the fastest implementations
+that don’t violate the other considerations. The compilation environment is considered. For example, if SSE is
+enabled, region multiplication in <em> GF(2<sup>4 </sup>) </em> employs a single multiplication table. If SSE is not enabled, then a
+"double" table is employed that performs table lookup two bytes at a time. </li><br>
+<li>
+<b>Memory Consumption:</b> We try to keep the memory footprint of GF-Complete low. For example, the fastest
+way to perform <b>multiply.w32()</b> in <em>GF(2<sup>32</sup>) </em> is to employ 1.75 MB of multiplication tables (see Section 7.4
+below). We do not include this as a default, however, because we want to keep the default memory consumption
+of GF-Complete low.
+</li>
+
+</ul>
+
+
+
+
+
+
+<br/>
+
+6 &nbsp &nbsp <em> THE DEFAULTS </em> <span id="index_number">14 </span> <br><br><br>
+
+<ul>
+
+3. &nbsp <b>Compatibility with "standard" implementations:</b> While there is no <em>de facto</em> standard of Galois Field arithmetic,
+most libraries implement the same fields. For that reason, we have not selected composite fields, alternate
+polynomials or memory layouts for the defaults, even though these would be faster. Again, see section 7.7 for
+more information.
+
+</ul>
+
+<p>Table 1 shows the default methods used for each power-of-two word size, their alignment parameters <em>s</em> and <em> t,</em> their
+memory consumption and their rough performance. The performance tests are on an Intel Core i7-3770 running at
+3.40 GHz, and are included solely to give a flavor of performance on a standard microprocessor. Some processors
+will be faster with some techniques and others will be slower, so we only put numbers in so that you can ballpark it.
+For other values of <em>w</em> between 1 and 31, we use table lookup when w &#8804 8, discrete logarithms when w &#8804 16 and
+"Bytwo<sub>p</sub>" for w &#8804 32. </p>

+Table 1: The default implementations, memory consumption and rough performance when w is a power of two. The
+variables s and t are alignment variables described in Section 5.
+<p>
+A few comments on Table 1 are in order. First, with SSE, the performance of <b>multiply()</b> is faster when <em> w </em> = 64
+than when<em> w </em> = 32. That is because the primitive polynomial for <em> w </em>= 32, that has historically been used in Galois
+Field implementations, is sub-ideal for using carry-free multiplication (PCLMUL). You can change this polynomial
+(see section 7.7) so that the performance matches <em>w </em> = 64. </p>
+<p>
+The region operations for <em> w </em>= 4 and <em>w </em>= 8 without SSE have been selected to have a low memory footprint. There
+are better options that consume more memory, or that only work on large memory regions (see section 6.1.5).
+</p>
+
+There are times that you may want to stray from the defaults. For example:
+<ul>
+<li>
+You may want better performance.
+</li>
+
+</ul>
+
+
+
+
+

+
+<ul>
+<li>You may want a lower memory footprint.</li>
+<li>You may want to use a different Galois Field or even a ring.</li>
+<li>You only care about multiplying a region by the value two.</li>
+
+</ul>
+
+
+<p>
+Our command line tools allow you to deviate from the defaults, and we have two C functions <b>-gf_init_hard()</b>
+and <b>create_gf_from_argv()</b> that can be called from application code to override the default methods. There are six
+command-line tools that can be used to explore the many techniques implemented in GF-Complete: </p>
+
+<ul><br>
+
+<li> <b>gf_methods</b> is a tool that enumerates most of the possible command-line arguments that can be sent to the other
+tools</li><br>
+<li> <b>gf_mult</b> and <b>gf_div</b> are explained above. You may change the multiplication and division technique in these
+tools if you desire</li><br>
+<li> <b>gf_unit</b> performs unit tests on a set of techniques to verify correctness</li><br>
+<li> <b> gf_time measures </b> the performance of a particular set of techniques</li><br>
+<li> <b>time_tool.sh </b> makes some quick calls to <b>gf_time</b> so that you may gauge rough performance.</li><br>
+<li> <b>gf_poly</b> tests the irreducibility of polynomials in a Galois Field</li><br>
+</ul>
+
+
+<p>To change the default behavior in application code, you need to call <b>gf_init_hard()</b> rather than <b>gf_init_easy().</b>
+Alternatively, you can use <b>create_g_from_argv(),</b> included from <b>gf_method.h,</b> which uses an <b>argv</b>-style array of
+strings to specify the options that you want. The procedure in <b>gf_method.c</b> parses the array and makes the proper
+<b>gf_init_hard()</b> procedure call. This is the technique used to parse the command line in <b> gf_mult, gf_div, gf_unit </b><em>et al.</em> </p>
+
+
+<h2>6.1.1 Changing the Components of a Galois Field with create <b>gf_from_argv()</b> </h2>
+There are five main components to every Galois Field instance:
+<ul>
+<li> <em>w </em> </li>
+<li> Multiplication technique </li>
+<li> Division technique </li>
+<li> Region technique(s) </li>
+<li> Polynomial </li>
+</ul>
+
+<p>The procedures <b>gf_init_hard()</b> and <b> create_gf_from_argv()</b> allow you to specify these parameters when you create
+your Galois Field instance. We focus first on <b>create_gf_from_argv(),</b> because that is how the tools allow you to specify
+the components. The prototype of <b>create_gf_from_argv()</b> is as follows: </p><br>
+
+<div id="number_spacing">
+int create_gf_from_argv(gf_t *gf, int w, int argc, char **argv, int starting);<br><br> </div>
+
+You pass it a pointer to a gf_t, which it will initialize. You specify the word size with the parameter <em><b>w,</b></em> and then you
+pass it an <b>argc/argv</b> pair as in any C or C++ program. You also specify a <b>starting</b> argument, which is where in <b>argv</b>
+the specifications begin. If it successfully parses <b>argc</b> and <b>argv,</b> then it creates the <b>gf_t</b> using <b>gf_init_hard()</b> (described
+below in section 6.4). It returns one past the last index of <b>argv</b> that it considered when creating the <b>gf_t.</b> If it fails, then
+it returns zero, and the <b>gf_t</b> is unmodified.
+
+
+
+<p>For example, <b>gf_mult.c</b> calls create gf_from_argv() by simply passing <b>argc</b> and <b>argv</b> from its <b>main()</b> declaration,
+and setting starting to 4.</p>
+
+
+
+
+
+
+
+
+<br/>
+
+6 &nbsp &nbsp <em> THE DEFAULTS </em> <span id="index_number">16 </span> <br><br><br>
+
+<p>
+To choose defaults, <b>argv[starting]</b> should equal "-". Otherwise, you specify the component that you are changing
+with "-m" for multiplication technique, "-d" for division technique, "-r" for region technique, and "-p" for the
+polynomial. You may change multiple components. You end your specification with a single dash. For example, the
+following call multiplies 6 and 5 in <em>GF(2<sup>4</sup>)</em> with polynomial 0x19 using the "SHIFT" technique for multiplication
+(we'll explain these parameters later):
+</p><br><br>
+
+<div id="number_spacing">
+UNIX> ./gf_mult 6 5 4 -p 0x19 -m SHIFT -<br>
+7 <br>
+UNIX> <br><br>
+</div>
+
+<p>If <b>create_gf_from_argv()</b> fails, then you can call the procedure <b>gf_error(),</b> which prints out the reason why <b>create_
+gf_from_argv()</b> failed. </p>
+
+
+<h2>6.1.2 Changing the Polynomial </h2>
+
+Galois Fields are typically implemented by representing numbers as polynomials with binary coefficients, and then
+using the properties of polynomials to define addition and multiplication. You do not need to understand any of that to
+use this library. However, if you want to learn more about polynomial representations and how they construct fields,
+please refer to The Paper.
+
+<p>Multiplication is based on a special polynomial that we will refer to here as the "defining polynomial." This
+polynomial has binary coefficients and is of degree <em> w.</em> You may change the polynomial with "-p" and then a number
+in hexadecimal (the leading "0x" is optional). It is assumed that the <em>w</em>-th bit of the polynomial is set - you may include
+it or omit it. For example, if you wish to set the polynomial for GF(2<sup>16</sup>) to x<sup>16</sup> + x<sup>5</sup> + x<sup>3</sup> + x<sup>2</sup> + 1, rather than its
+default of x<sup>16</sup> + x<sup>12</sup> + x<sup>3</sup> + x + 1, you may say "-p 0x1002d," "-p 1002d," "-p 0x2d" or "-p 2d."
+We discuss changing the polynomial for three reasons in other sections: </p>
+<ul>
+<li>Leveraging carry-free multiplication (section 7.7). </li>
+<li>Defining composite fields (section 7.6). </li>
+<li>Implementing rings (section 7.8.1). </li>
+
+</ul>
+
+<p>
+Some words about nomenclature with respect to the polynomial. A Galois Field requires the polynomial to be
+<em>irreducible </em>.. That means that it cannot be factored. For example, when the coefficients are binary, the polynomial x<sup>5</sup>+
+x<sup>4</sup>+x+1 may be factored as (x<sup>4</sup>+1)(x+1). Therefore it is not irreducible and cannot be used to define a Galois Field.
+It may, however, be used to define a ring. Please see section 7.8.1 for a discussion of ring support in GF-Complete. </p>
+<p>
+There is a subset of irreducible polynomials called primitive. These have an important property that one may enumerate
+all of the elements of the field by raising 2 to successive posers. All of the default polynomials in GF-Complete
+are primitive. However, so long as a polynomial is irreducible, it defines a Galois Field. Please see section 7.7 for a
+further discussion of the polynomial. </p>
+
+<p>
+One thing that we want to stress here is that changing the polynomial changes the field, so fields with different
+polynomialsmay not be used interchangeably. So long as the polynomial is irreducible, it generates a Galois Field that
+is isomorphic to all other Galois Fields; however the multiplication and division of elements will differ. For example,
+the polynomials 0x13 (the default) and 0x19 in <em>GF(2<sup>4</sup>) </em> are both irreducible, so both generate valid Galois Fields.
+However, their multiplication differs: </p><br>

+<h3>6.1.3 &nbsp &nbsp Changing the Multiplication Technique </h3>
+The following list describes the multiplication techinques that may be changed with "-m". We keep the description
+here brief. Please refer to The Paper for detailed descriptions of these techniques.<br><br>
+
+
+<li><b> "TABLE:" </b> Multiplication and division are implemented with tables. The tables consume quite a bit of memory
+(2<sup>w</sup> &#215 2 <sup>w</sup> &#215 <sup>w</sup>/
+8 bytes), so they are most useful when <em>w</em> is small. Please see <b>"SSE," "LAZY," "DOUBLE"</b> and
+
+<b>"QUAD"</b> under region techniques below for further modifications to <b>"TABLE"</b> to perform <b>multiply_region()</b></li><br>
+
+
+<li> <b>"LOG:"</b> This employs discrete (or "Zeph") logarithm <b>tables</b> to implement multiplication and division. The
+memory usage is roughly (3 &#215 2<sup>w</sup> &#215 w /
+8 bytes), so they are most useful when w is small, but they tolerate
+larger <em>w</em> than <b>"TABLE."</b> If the polynomial is not primitive (see section 6.1.2), then you cannot use <b>"LOG"</b> as
+an implementation. In that case,<b> gf_init_hard()</b> or <b>create_gf_from_argv()</b> will fail</li><br>
+
+
+<li><b> "LOG_ZERO:"</b> Discrete logarithm tables which include extra room for zero entries. This more than doubles
+the memory consumption to remove an <b>if</b> statement (please see [GMS08] or The Paper for more description). It
+doesn’t really make a huge deal of difference in performance</li><br>
+
+<li> <b>"LOG_ZERO_EXT:"</b> This expends even more memory to remove another <b>if</b> statement. Again, please see The
+Paper for an explanation. As with <b>"LOG_ZERO,"</b> the performance difference is negligible</li><br>
+
+<li> <b>"SHIFT:"</b> Implementation straight from the definition of Galois Field multiplication, by shifting and XOR-ing,
+then reducing the product using the polynomial. This is <em>slooooooooow,</em> so we don’t recommend you use it</li><br>
+
+
+<li> <b>"CARRY_FREE:"</b> This is identical to <b>"SHIFT,"</b> however it leverages the SSE instruction PCLMUL to perform
+carry-freemultiplications in single instructions. As such, it is the fastest way to perform multiplication for large
+values of <em>w</em> when that instruction is available. Its performance depends on the polynomial used. See The Paper
+for details, and see section 7.7 below for the speedups available when <em>w </em>= 16 and <em>w</em> = 32 if you use a different
+polynomial than the default one</li><br>
+
+
+<li> <b>"BYTWO_p:"</b> This implements multiplication by successively multiplying the product by two and selectively
+XOR-ing the multiplicand. See The Paper for more detail. It can leverage Anvin’s optimization that multiplies
+64 and 128 bits of numbers in <em>GF(2<sup>w</sup>) </em> by two with just a few instructions. The SSE version requires SSE2</li><br>
+
+
+<li> <b>"BYTWO_b:"</b> This implements multiplication by successively multiplying the multiplicand by two and selectively
+XOR-ing it into the product. It can also leverage Anvin's optimization, and it has the feature that when
+you're multiplying a region by a very small constant (like 2), it can terminate the multiplication early. As such,
+if you are multiplying regions of bytes by two (as in the Linux RAID-6 Reed-Solomon code [Anv09]), this is
+the fastest of the techniques, regardless of the value of <em>w.</em> The SSE version requires SSE2</li><br>
+
+
+<li> <b>"SPLIT:"</b> Split multiplication tables (like the LR tables in [GMS08], or the SIMD tables for w &#8804 8 in [LHy08,
+Anv09, PGM13b]). This argument must be followed by two more arguments, w<sub>a</sub> and w<sub>b</sub>, which are the index
+sizes of the sub-tables. This implementation reduces the size of the table from <b>"TABLE,"</b> but requires multiple
+</li><br>
+
+
+
+
+
+
+<br/>
+
+6 &nbsp &nbsp <em> THE DEFAULTS </em> <span id="index_number">18 </span> <br><br><br>
+<ul>
+table lookups. For example, the following multiplies 100 and 200 in <em>GF(2<sup>8</sup>) </em> using two 4K tables, as opposed
+to one 64K table when you use <b>"TABLE:"</b><br><br>
+<div id="number_spacing">
+UNIX> ./gf_mult 100 200 8 -m SPLIT 8 4 - <br>
+79<br>
+UNIX><br><br>
+</div>
+
+See section 7.4 for additional information on the arguments to <b>"SPLIT."</b> The SSE version typically requires
+SSSE3.<br><br>
+
+
+<li> <b>"GROUP:"</b> This implements the "left-to-right comb" technique [LBOX12]. I'm afraid we don't like that name,
+so we call it <b>"GROUP,"</b> because it performs table lookup on groups of bits for shifting (left) and reducing (right).
+It takes two additional arguments - g<sub>s,</sub> which is the number of bits you use while shifting (left) and g<sub>r</sub>, which
+is the number of bits you use while reducing (right). Increasing these arguments can you higher computational
+speed, but requires more memory. SSE version exists only for <em> w </em> = 128 and it requires SSE4. For more
+description on the arguments g<sub>s</sub> and g<sub>r</sub>, see section 7.5. For a full description of <b>"GROUP"</b> algorithm, please
+see The Paper.
+</li><br>
+
+<li> <b>"COMPOSITE:"</b> This allows you to perform operations on a composite Galois Field, <em> GF((2<sup>l</sup>)<sup>k</sup>)</em> as described
+in [GMS08], [LBOX12] and The Paper. The field size <em>w </em> is equal to <em>lk.</em> It takes one argument, which is <em>k,</em> and
+then a specification of the base field. Currently, the only value of <em>k</em> that is supported is two. However, that may
+change in a future revision of the library. </li><br>
+
+
+In order to specify the base field, put appropriate flags after specifying <em>k.</em> The single dash ends the base field,
+and after that, you may continue making specifications for the composite field. This process can be continued
+for multiple layers of <b>"COMPOSITE."</b> As an example, the following multiplies 1000000 and 2000000
+in <em>GF((2<sup>16</sup>)<sup>2</sup>),</em> where the base field uses <b>BYTWO_p</b> for multiplication: <br><br>
+<center>./gf_mult 1000000 2000000 32 -m COMPOSITE 2 <span style="color:red">-m BYTWO_p - -</span> </center><br>
+
+In the above example, the red text applies to the base field, and the black text applies to the composite field.
+Composite fields have two defining polynomials - one for the composite field, and one for the base field. Thus, if
+you want to change polynomials, you should change both. The polynomial for the composite field must be of the
+form x<sup>2</sup>+sx+1, where s is an element of <em>GF(2<sup>k</sup>).</em> To change it, you specify s (in hexadecimal)with "-p." In the
+example below, we multiply 20000 and 30000 in <em>GF((2<sup>8</sup>)<sup>2</sup>) </em>, setting s to three, and using x<sup>8</sup>+x<sup>4</sup>+x<sup>3</sup>+x<sup>2</sup>+1
+as the polynomial for the base field: <br><br>
+
+<center>./gf_mult 20000 30000 16 -m COMPOSITE 2 <span style="color:red">-p 0x11d </span> - -p 0x3 - </center> <br><br>
+
+If you use composite fields, you should consider using <b>"ALTMAP"</b> as well. The reason is that the region
+operations will go much faster. Please see section 7.6.<br><br>
+As with changing the polynomial, when you use a composite field, <em> GF((2<sup>l</sup>)<sup>k</sup>)</em>, you are using a different field
+than the "standard" field for <em> GF((2<sup>l</sup>)<sup>k</sup>)</em>. All Galois Fields are isomorphic to each other, so they all have the
+desired properties; however, the fields themselves change when you use composite fields.<br><br>
+</ul>
+<p>
+With the exception of <b>"COMPOSITE"</b>, only one multiplication technique can be provided for a given Galois
+Field instance. Composite fields may use composite fields as their base fields, in which case the specification will be
+recursive. </p>

+6 &nbsp &nbsp <em> THE DEFAULTS </em> <span id="index_number">19 </span> <br><br><br>
+
+<h3>6.1.4 &nbsp &nbsp &nbsp Changing the Division Technique </h3>
+
+There are two techniques for division that may be set with "-d". If "-d" is not specified, then appropriate defaults
+are employed. For example, when the multiplication technique is <b>"TABLE,"</b> a table is created for division as well as
+multiplication. When <b>"LOG"</b> is specified, the logarithm tables are used for division. With <b>"COMPOSITE,"</b> a special
+variant of Euclid's algorithm is employed that performs division using multiplication and division in the base field.
+Otherwise, Euclid's algorithm is used. Please see The Paper for a description of Euclid's algorithm applied to Galois
+Fields.
+
+<p>If you use "-d", you must also specify the multiplication technique with "-m." </p>
+<p>To force Euclid's algorithm instead of the defaults, you may specify it with "-d EUCLID." If instead, you would
+rather convert elements of a Galois Field to a binary matrix and find an element's inverse by inverting the matrix,
+then specify "-d MATRIX." In all of our tests, <b>"MATRIX"</b> is slower than <b>"EUCLID." "MATRIX" </b> is also not defined
+for <em>w </em> > 32.
+</p>
+
+
+<h3>6.1.5 &nbsp&nbsp&nbsp Changing the Region Technique </h3>
+The following are the region multiplication options ("-r"):
+<ul>
+<li>
+<b>"SSE:"</b> Use SSE instructions. Initialization will fail if the instructions aren't supported. Table 2 details the
+multiplication techniques which can leverage SSE instructions and which versions of SSE are required. </li><br>

+
+
+
+
+
+
+
+
+
+<li> <b>"NOSSE:"</b> Force non-SSE version </li><br>
+
+<li> <b> "DOUBLE:"</b> Use a table that is indexed on two words rather than one. This applies only to <em>w </em> = 4, where
+the table is indexed on bytes rather than 4-bit quantities, and to <em>w </em> = 8, where the table is indexed on shorts
+rather than bytes. In each case, the table lookup performs two multiplications at a time, which makes region
+multiplication faster. It doubles the size of the lookup table. </li><br>
+
+<li> <b>"QUAD:"</b> Use a table that is indexed on four words rather than two or one. This only applies to <em>w </em> = 4, where
+the table is indexed on shorts. The "Quad" table may be lazily created or created ahead of time (the default). If
+the latter, then it consumes 2<sup>4</sup> &#215 2<sup>16</sup> &#215 2 = 2 MB of memory. </li><br>
+
+<li> <b> "LAZY:"</b> Typically it's clear whether tables are constructed upon initialization or lazily when a region operation
+is performed. There are two times where it is ambiguous: <b>"QUAD"</b> when <em>w </em> = 4 and <b>"DOUBLE"</b> when <em>w </em> = 8.
+If you don't specify anything, these tables are created upon initialization, consuming a lot of memory. If you
+specify <b>"LAZY,"</b> then the necessary row of the table is created lazily when you call <b>"multiply_region().</b>
+</li>
+
+</ul>
+
+
+
+

+
+
+
+
+
+
+<br/>
+
+6 &nbsp &nbsp <em> THE DEFAULTS </em> <span id="index_number">20 </span> <br><br><br>
+<ul>
+
+<li> <b>"ALTMAP:"</b> Use an alternate mapping, where words are split across different subregions of memory. There
+are two places where this matters. The first is when implementing "<b>SPLIT</b> <em>w </em> 4" using SSE when <em>w </em> > 8. In
+these cases, each byte of the word is stored in a different 128-bit vector, which allows the implementation to
+better leverage 16-byte table lookups. See section 7.4 for examples, and The Paper or [PGM13b] for detailed
+explanations.<br><br> </li>
+
+The second place where it matters is when using <b>"COMPOSITE."</b> In this case, it is advantageous to split each
+memory region into two chunks, and to store half of each word in a different chunk. This allows us to call
+<b>region_multiply() </b> recursively on the base field, which is <em>much </em> faster than the alternative. See Section 7.6 for
+examples, and The Paper for an explanation.<br><br>
+
+It is important to note that with <b>"ALTMAP,"</b> the words are not "converted" from a standard mapping to an
+alternate mapping and back again. They are assumed to always be in the alternate mapping. This typically
+doesn't matter, so long as you always use the same <b>"ALTMAP"</b> calls. Please see section 7.9 for further details
+on <b>"ALTMAP,"</b> especially with respect to alignment.<br><br>
+
+<li> <b>"CAUCHY:"</b> Break memory into <em>w </em> subregions and perform only XOR's as in Cauchy Reed-Solomon coding
+[BKK<sup>+</sup>95] (also described in The Paper). This works for <em>any</em> value of <em>w </em> &#8804 32, even those that are not
+powers of two. If SSE2 is available, then XOR's work 128 bits at a time. For <b>"CAUCHY"</b> to work correctly,
+<em>size</em> must be a multiple of <em>w </em>.</li> </ul>
+
+
+
+<p>It is possible to combine region multiplication options. This is fully supported as long as <b>gf_methods</b> has the combination
+listed. If multiple region options are required, they should be specified independently (as flags for <b>gf_init_hard()</b>
+and independent options for command-line tools and <b>create_gf_from_argv()).</b> </p>
+
+
+<h3>6.2 &nbsp&nbsp&nbspDetermining Supported Techniques with gf_methods </h3>
+
+
+The program <b>gf_methods</b> prints a list of supported methods on standard output. It is called as follows:<br><br>
+<div id="number_spacing">
+<center>./gf_methods <em>w </em> -BADC -LUMDRB <br><br> </center> </div>
+
+The first argument is <em>w </em>, which may be any legal value of <em>w </em>. The second argument has the following flags: <br><br>
+<ul>
+
+<li> <b>"B:"</b> This only prints out "basic" methods that are useful for the given value of <em>w </em>. It omits <b>"SHIFT"</b> and other
+methods that are never really going to be useful.</li><br>
+
+<li> <b> "A:"</b> In constrast, this specifies to print "all" methods. </li><br>
+
+<li> <b>"D:"</b> This includes the <b>"EUCLID"</b> and <b>"MATRIX"</b> methods for division. By default, they are not included. </li><br>
+
+<li> <b>"C:"</b> This includes the <b>"CAUCHY"</b> methods for region multiplication. By default, it is not included.</li> <br>
+</ul>
+<p>
+You may specify multiple of these as the second argument. If you include both <b>"B"</b> and <b>"A,"</b> then it uses the last
+one specified. </p>
+<p>
+The last argument determines the output format of <b>gf_methods.</b> If it is <b>"L,"</b> then it simply lists methods. If it
+is <b>"U,"</b> then the output contains <b>gf_unit</b> commands for each of the methods. For the others, the output contains
+<b>gf_time_tool.sh</b> commands for <b>M </b>ultiplication,<b>D</b>ivision,<b>R</b>egion multiplications with multiple buffer sizes, and the

+<h3>6.3 Testing with <b>gf_unit </b>, <b>gf_time </b>, and time_tool.sh </h3>
+
+
+
+<b>gf_unit </b> and <b>gf_time </b> may be used to verify that a combination of arguments works correctly and efficiently on your
+platform. If you plan to stray from the defaults, it is probably best to run both tools to ensure there are no issues with
+your environment. <b>gf_unit </b> will run a set of unit tests based on the arguments provided to the tool, and <b>gf_time </b> will
+time Galois Field methods based on the provided arguments.<br>
+The usage of gf_ unit is:<br><br>
+<div id="number_spacing">
+<b>gf_unit </b> w tests seed method<br><br> </div>
+The usage of gf_ time is:<br><br>
+<div id="number_spacing">
+<b>gf_time </b> w tests seed buffer-size iterations method<br><br>
+</div>
+
+
+
+The seed is an integer- negative one uses the current time. The tests are specified by a listing of characters. The
+following tests are supported (All are supported by <b>gf_time.</b> Only ', 'S' and 'R' are supported by <b>gf_unit</b>):<br><br>
+
+<ul>
+<li> <b>'M':</b> Single multiplications</li><br>
+<li> <b> 'D':</b> Single divisions</li><br>
+<li> <b> 'I':</b> Single inverses</li><br>
+<li> <b>'G': </b> Region multiplication of a buffer by a random constant</li><br>
+<li> <b>'0': </b> Region multiplication of a buffer by zero (does nothing and<b>bzero()</b>)</li><br>
+<li> <b>'1': </b> Region multiplication of a buffer by one (does <b>memcpy()</b> and <b>XOR</b>)</li><br>
+<li> <b>'2': </b> Region multiplication of a buffer by two – sometimes this is faster than general multiplication</li><br>
+<li> <b>'S':</b> All three single tests</li><br>
+<li> <b>'R':</b> All four region tests</li><br>
+<li> <b>'A':</b> All seven tests</li><br>
+</ul>
+
+
+
+
+
+<p>Here are some examples of calling <b>gf_unit</b> and <b>gf_time</b> to verify that <b>"-m SPLIT 32 4 -r ALTMAP -"</b> works
+in <em>GF(2<sup>32</sup>),</em> and to get a feel for its performance. First, we go to the test directory and call <b>gf_unit:</b> </p><br><br>
+
+
+<div id="number_spacing">
+UNIX> cd test <br>
+UNIX> ./gf_unit 32 A -1 -m SPLIT 32 4 -r ALTMAP - <br>
+Args: 32 A -1 -m SPLIT 32 4 -r ALTMAP - / size (bytes): 684 <br>
+UNIX> <br><br>
+</div>
+
+<b>gf_unit</b> reports on the arguments and how may bytes the <b>gf_t</b> consumes. If it discovers any problems or inconsistencies
+with multiplication, division or region multiplication, it will report them. Here, there are no problems.
+Next, we move to the <b>tools</b> directory and run performance tests on a 10K buffer, with 10,000 iterations of each test:<br><br>
+
+
+UNIX> cd ../tools <br>
+UNIX> ./gf_time 32 A -1 10240 10000 -m SPLIT 32 4 -r ALTMAP -<br>

+We say that <b>time_tool.sh </b>is "rough" because it tries to limit each test to 5 ms or less. Thus, the time granularity
+is fine, which means that the numbers may not be as precise as they could be were the time granularity to be course.

+The default is quite a bit slower than the best performing methods for both single and region multiplication. So
+why are the defaults the way that they are? As detailed at the beginning of this chapter, we strive for lower memory
+consumption, so we don't use <b>"SPLIT 8 8,"</b> which consumes 1.75MB.We don't implement alternate fields by default,
+which is why we don't use <b>"COMPOSITE."</b> Finally, we don't implement alternate mappings of memory by default,
+which is why we don't use "<b>-m SPLIT 32 4 -r ALTMAP -.</b>"</p>
+
+<p>Of course, you may change these defaults if you please.</p>
+<p>
+<b>Test question:</b> Given the numbers above, it would appear that <b>"COMPOSITE"</b> yields the fastest performance of
+single multiplication, while "SPLIT 32 4" yields the fastest performance of region multiplication. Should I use two
+gf_t's in my application – one for single multiplication that uses <b>"COMPOSITE,"</b> and one for region multiplication
+that uses <b>"SPLIT 32 4?"</b></p>
+<p>
+The answer to this is "no." Why? Because composite fields are different from the "standard" fields, and if you mix
+these two <b>gf_t</b>'s, then you are using different fields for single multiplication and region multiplication. Please read
+section 7.2 for a little more information on this.</p>
+
+<h3>6.4 &nbsp &nbsp &nbspCalling gf_init_hard()</h3>
+
+We recommend that you use <b>create_gf_from_argv()</b> instead of <b>gf_init_hard().</b> However, there are extra things that
+you can do with <b>gf_init_hard().</b> Here's the prototype:<br><br>
+<div id="number_spacing">
+int gf_init_hard(gf_t *gf<br>
+<div style="padding-left:100px">
+int w<br>
+int mult_type<br>
+int region_type<br>
+int divide_type<br>
+uint64_t prim_poly<br>
+int arg1<br>
+int arg2<br>
+</div>
+</div>
+
+
+
+
+
+
+
+
+<br/>
+
+6 &nbsp &nbsp <em> THE DEFAULTS </em> <span id="index_number">25 </span> <br><br><br>
+<div id="number_spacing">
+<div style="padding-left:100px">
+GFP base_gf, <br>
+void *scratch_memory); </div><br><br>
+
+
+The arguments mult type, region type and divide type allow for the same specifications as above, except the
+types are integer constants defined in gf_complete.h: <br><br>
+typedef enum {GF_MULT_DEFAULT,<br>
+<div style="padding-left:124px">
+GF_MULT_SHIFT<br>
+GF_MULT_CARRY_FREE<br>
+GF_MULT_GROUP<br>

+GF_MULT_TABLE<br>
+GF_MULT_LOG_TABLE<br>
+GF_MULT_LOG_ZERO<br>
+GF_MULT_LOG_ZERO_EXT<br>
+GF_MULT_SPLIT_TABLE<br>
+GF_MULT_COMPOSITE } gf_mult_type_t;<br><br>
+
+</div>
+
+#define GF_REGION_DEFAULT (0x0)<br>
+#define GF_REGION_DOUBLE_TABLE (0x1) <br>
+#define GF_REGION_QUAD_TABLE (0x2) <br>
+#define GF_REGION_LAZY (0x4) <br>
+#define GF_REGION_SSE (0x8) <br>
+#define GF_REGION_NOSSE (0x10) <br>
+#define GF_REGION_ALTMAP (0x20) <br>
+#define GF_REGION_CAUCHY (0x40) <br><br>
+typedef enum { GF_DIVIDE_DEFAULT<br>
+<div style="padding-left:130px">GF_DIVIDE_MATRIX<br>
+GF_DIVIDE_EUCLID } gf_division_type_t;<br><br>
+</div>
+</div>
+<p>
+You can mix the region types with bitwise or. The arguments to <b>GF_MULT_GROUP,GF_MULT_SPLIT_TABLE</b>
+and <b>GF_MULT_COMPOSITE</b> are specified in arg1 and arg2. <b>GF_MULT_COMPOSITE</b> also takes a base field
+in <b>base_gf.</b> The base field is itself a <b>gf_t,</b> which should have been created previously with <b>create_gf_fro_argv(),</b>
+<b>gf_init_easy()</b> or <b>gf_init_hard().</b> Note that this <b>base_gf</b> has its own <b>base_gf</b> member and can be a composite field
+itself.</p>
+<p>
+You can specify an alternate polynomial in <b>prim_poly.</b> For <em>w </em>&#8804 32, the leftmost one (the one in bit position <em>w</em>) is
+optional. If you omit it, it will be added for you. For <em>w </em> = 64, there's no room for that one, so you have to leave it off.
+For <em>w </em>= 128, your polynomial can only use the bottom-most 64 bits. Fortunately, the standard polynomial only uses
+those bits. If you set <b>prim_poly</b> to zero, the library selects the "standard" polynomial.
+</p>
+<p>
+Finally, <b>scratch_memory</b> is there in case you don't want <b>gf_init_hard()</b> to call <b>malloc()</b>. Youmay call <b>gf_scratch_size()</b>
+to find out how much extra memory each technique uses, and then you may pass it a pointer for it to use in <b>scratc_memory.</b>
+If you set scratch memory to NULL, then the extra memory is allocated for you with <b>malloc().</b> If you use <b>gf_init_easy()</b>
+or <b>create_gf_from_argv(),</b> or you use <b>gf_init_hard()</b> and set <b>scratch_memory</b> to <b>NULL,</b> then you should call <b>gf_free()</b>
+to free memory. If you use <b>gf_init_hard()</b> and use your own <b>scratch_memory</b> you can still call <b>gf_free(),</b> and it will
+not do anything.</p>
+<p>
+Both <b>gf_init_hard()</b> and <b>gf_scratch_size()</b> return zero if the arguments don't specify a valid <b>gf_t.</b> When that happens,
+you can call <b>gf_error()</b> to print why the call failed.</p>
+
+

+
+
+6 &nbsp &nbsp <em> FURTHER INFORMATION ON OPTIONS AND ALGORITHMS </em> <span id="index_number">26 </span> <br><br><br>
+
+
+<p>We'll give you one example of calling <b>gf_ init_hard().</b> Suppose you want to make a <b>gf_ init_hard()</b> call to be
+equivalent to "-m SPLIT 16 4 -r SSE -r ALTMAP -" and you want to allocate the scratch space yourself. Then you'd
+do the following:</p><br><br>
+
+<div id="number_spacing">
+gf_t gf; <br>
+void *scratch; <br>
+int size; <br>
+size = gf_scratch_size(16, GF_MULT_SPLIT_TABLE,<br>
+GF_REGION_SSE | GF_REGION_ALTMAP,<br>
+GF_DIVIDE_DEFAULT,<br>
+16, 4); <br>
+if (size == 0) { gf_error(); exit(1); } /* It failed. That shouldn’t happen */<br>
+scratch = (void *) malloc(size); <br>
+if (scratch == NULL) { perror("malloc"); exit(1); } <br>
+if (!gf_init_hard(&gf, 16, GF_MULT_SPLIT_TABLE, <br>
+GF_REGION_SSE | GF_REGION_ALTMAP, <br>
+GF_DIVIDE_DEFAULT,<br>
+0, 16, 4, NULL, scratch)) { <br>
+gf_error(); <br>
+exit(1); <br>
+} <br>
+
+</div>
+
+
+<h3>6.5 &nbsp &nbsp gf_size() </h3>
+
+You can call <b>gf_size(gf_t *gf)</b> to learn the memory consumption of the <b>gf_t.</b> It returns all memory consumed by the
+<b>gf_t,</b> including the <b>gf_t</b> itself, any scratch memory required by the gf_ t, and the memory consumed by the sub-field

+7.1 &nbsp Inlining Single Multiplication and Division for Speed </h3>
+
+Obviously, procedure calls are more expensive than single instructions, and the mechanics of multiplication in <b>"TABLE"</b>
+and <b>"LOG"</b> are pretty simple. For that reason, we support inlining for <b>"TABLE"</b> when <em>w </em> = 4 and <em>w </em> = 8, and
+for <b>"LOG"</b> when <em>w </em> = 16. We elaborate below.
+<p>
+When <em>w </em> = 4, you may inline multiplication and division as follows. The following procedures return pointers to
+the multiplication and division tables respectively: </p> <br><br>
+
+<div id="number_spacing">
+uint8_t *gf_w4_get_mult_table(gf_t * gf);<br>
+uint8_t *gf_w4_get_div_table(gf_t * gf);<br><br>
+</div>
+<p>The macro <b>Gf_W4_INLINE_MULTDIV </b>(<em>table, a, b</em>) then multiplies or divides <em>a </em> by <em>b</em> using the given table. This
+of course only works if the multiplication technique is <b>"TABLE,"</b> which is the default for <em>w </em> = 4. If the multiplication
+technique is not <b>"TABLE,"</b> then <b>gf_w4_get_mult_table()</b> will return <b>NULL.</b></p>

+
+
+
+
+<p>When <em>w </em> = 8, the procedures <b>gf_w8_et_mult_table()</b> and <b>gf_ w8_get_div_table(),</b> and the macro </p>
+
+<b>GF_W8_INLINE_MULTDIV </b>(<em>table, a, b</em>) work identically to the <em>w </em> = 4 case.
+
+<p>When <em>w </em> = 16, the following procedures return pointers to the logarithm table, and the two inverse logarithm tables
+respectively: </p><br>
+
+<div id="number_spacing">
+uint16_t *gf_w16_get_log_table(gf_t * gf); <br>

+uint16_t *gf_w16_get_div_alog_table(gf_t * gf);<br>
+
+</div>
+<br>
+<p>
+The first inverse logarithm table works for multiplication, and the second works for division. They actually point
+to the same table, but to different places in the table. You may then use the macro <b>GF_W16_INLINE_MULT</b>(<em>log,
+alog, a, b </em>) to multiply <em>a</em> and <em>b</em>, and the macro <b>GF_W16_INLINE_DIV </b>(<em>log, alog, a, b </em>) to divide a and b. Make
+sure you use the <em>alog</em> table returned by <b>gf_w16_get_mult_alog_table()</b> for multiplication and the one returned by
+<b>gf_w16_get_div_alog_table()</b> for division. Here are some timings: </p> <br><br>

+7.2 &nbsp &nbsp Using different techniques for single and region multiplication </h3>
+
+
+You may want to "mix and match" the techniques. For example, suppose you'd like to use "-m SPLIT 8 8" for
+<b>multiply()</b> in <em>GF(2<sup>32</sup>),</em> because it's fast, and you don't mind consuming all of that space for tables. However, for
+<b>multiply_region(),</b> you'd like to use "-m SPLIT 32 4 -r ALTMAP," because that's the fastest way to implement
+<b>multiply_region().</b> Unfortunately, There is no way to create a <b>gf_t</b> that does this combination. In this case, you should
+simply create two <b>gf_t's,</b> and use one for <b>multiply()</b> and the other for <b>multiply_region().</b> All of the implementations
+may be used interchangably with the following exceptions:
+
+<ul>
+<li>
+<b>"COMPOSITE"</b> implements a different Galois Field. </li><br>
+
+<li>If you change a field's polynomial, then the resulting Galois Field will be different. </li>
+
+</ul>

+
+<ul>
+<li>
+
+If you are using <b>"ALTMAP"</b> to multiply regions, then the contents of the resulting regions of memory will
+depend on the multiplication technique, the size of the region and its alignment. Please see section 7.9 for a
+detailed explanation of this. </li>
+
+<li>If you are using <b>"CAUCHY"</b> to multiply regions, then like <b>"ALTMAP,"</b> the contents of the result regions of

+
+<h3>7.3 &nbsp &nbsp General <em>w </em> </h3>
+The library supports Galois Field arithmetic with 2 < <em>w </em> &#8804 32. Values of <em>w </em> which are not whole number powers of
+2 are handled by the functions in <b>gf_wgen.c</b> . For these values of <em>w </em>, the available multiplication types are <b>"SHIFT,"
+"BYT<em>w </em>O p," "BYT<em>w </em>O b," "GROUP," "TABLE"</b> and <b>"LOG." "LOG" </b> is only valid for <em>w </em> < 28 and <b>"TABLE"</b>
+
+is only valid for <em>w </em> < 15. The defaults for these values of <em>w </em> are <b>"TABLE"</b> for <em>w </em> < 8, <b>"LOG"</b> for <em>w </em> < 16, and
+<b>"BYT<em>w </em>O p"</b> for <em>w </em> < 32.<br><br>
+
+<h3>7.4 Arguments to "SPLIT" </h3>
+
+The "SPLIT" technique is based on the distributive property of multiplication and addition: <br><br>
+<center>
+a * (b + c) = (a * b) + (a * c). </center>
+<br>
+This property allo<em>w </em>s us to, for example, split an eight bit <em>w </em>ord into t<em>w </em>o four-bit components and calculate the product
+by performing t<em>w </em>o table lookups in 16-element tables on each of the compoents, and adding the result. There is much
+more information on <b>"SPLIT"</b> in The Paper. Here <em>w </em>e describe the version of <b>"SPLIT"</b> implemented in GF-Complete.
+
+<p>
+<b>"SPLIT"</b> takes t<em>w </em>o arguments, <em>w </em>hich are the number of bits in each component of a, <em>w </em>hich <em>w </em>e call <em>w </em><sub>a</sub>, and the
+number of bits in each component of b, <em>w </em>hich <em>w </em>e call <em>w </em><sub>b.</sub> If the t<em>w </em>o differ, it does not matter <em>w </em>hich is bigger - the
+library recognizes this and performs the correct implementation. The legal values of <em>w </em><sub>a</sub> and <em>w </em><sub>b</sub> fall into five categories:
+</p><br>
+
+
+<ol>
+<li>
+ <em>w </em><sub>a</sub> is equal to <em>w </em> and <em>w </em><sub>b</sub> is equal to four. In this case, b is broken up into <em>w </em>/4
+four-bit <em>w </em>ords <em>w </em>hich are used
+in 16-element lookup tables. The tables are created on demand in <b>multiply_region()</b> and the SSSE3 instruction
+
+<b>mm_shuffle_epi8()</b> is leveraged to perform 16 lookups in parallel. Thus, these are very fast implementations.
+<em>w </em>hen <em>w </em> &#8805 16, you should combine this <em>w </em>ith <b>"ALTMAP"</b> to get the best performance (see The Paper
+or [PGM13b] for explanation). If you do this please see section 7.9 for information about <b>"ALTMAP"</b> and
+alignment.<br><br>
+
+
+If you don't use <b>"ALTMAP,"</b> the implementations for <em>w </em> &#8712 {16, 32, 64} convert the standard representation into
+<b>"ALTMAP,"</b> perform the multiplication <em>w </em>ith <b>"ALTMAP"</b> and then convert back to the standard representation.
+The performance difference using <b>"ALTMAP"</b> can be significant: <br><br><br>

+
+<h2>7.5 &nbsp&nbsp Arguments to "GROUP" </h3>
+
+The <b>"GROUP"</b> multiplication option takes t<em>w </em>o arguments, g<sub>s</sub> and g<sub>r</sub>. It implements multiplication in the same manner
+as <b>"SHIFT,"</b> except it uses a table of size 2<sup>gs</sup> to perform g<sup>s</sup> shifts at a time, and a table of size 2<sup>gr</sup> to perform g<sup>r</sup>
+reductions at at time. The program <b>gf_methods</b> only prints the options 4 4 and 4 8 as arguments for <b>"GROUP."</b>
+However, other values of g<sub>s</sub> and g<sub>r</sub> are legal and sometimes desirable: <br><br>
+
+<ol>
+<li>
+ For <em>w </em> &#8804 32 and <em>w </em> = 64, any values of g<sub>s</sub> and g<sub>r</sub> may be used, so long as they are less than or equal to <em>w </em> and so
+long as the tables fit into memory. There are four exceptions to this, listed belo<em>w </em>. </li><br>
+<li> For <em>w </em> = 4, <b>"GROUP"</b> is not supported. </li><br>
+<li> For <em>w </em> = 8, <b>"GROUP"</b> is not supported. </li><br>
+<li> For <em>w </em> = 16, <b>"GROUP"</b> is only supported for gs = gr = 4. </li><br>
+<li> For <em>w </em> = 128 <b>"GROUP"</b> only supports <em>g<sub>s</sub></em> = 4 and <em> g<sub>r</b> </em> &#8712 {4, 8, 16}.</li><br>
+</ol>
+<p>
+The way that gs and gr impact performance is as follows. The <b>"SHIFT"</b> implementation works by performing a
+carry-free multiplication in <em>w </em> steps, and then performing reduction in <em>w </em> steps. In "GROUP," the carry-free multiplication
+is reduced to <em>w /</em>g<sub>s</sub>steps, and the reduction is reduced to <em>w /</em>g<sub>r</sub>
+
+. Both require tables. The table for the carry-free
+multiplication must be created at the beginning of each <b>multiply()</b> or <b>multiply_region(),</b> while the table for reduction
+is created when the <b>gf_t</b> is initialized. For that reason, it makes sense for g<sub>r</sub> to be bigger than g<sub>s.</sub></p>
+
+<p>
+To give a flavor for the impact of these arguments, Figure 3 show </em>s the performance of varying g<sub>s</sub> and g<sub>r</sub> for
+single multiplication and region multiplication respectively, in <em> GF(2<sup>32</sup>)</em> and <em>GF(2<sup>64</sup>).</em> As the graphs demonstrate,
+<b>multiply()</b> performs better <em>w </em>ith smaller values of gs, <em>w </em>hile multiply region() amortizes the creation of the shifting
+table, and can tolerate larger values of g<sub>s.</sub> <em>w </em>hen g<sub>s</sub> equals g<sub>r,</sub> there are some optimizations that we hand-encode.
+These can be seen clearly in the <b>multiply_region()</b> graphs.

+<h3>7.6 &nbspConsiderations with "COMPOSITE" </h3>
+
+
+As mentioned above, using <b>"ALTMAP"</b> with <b>"COMPOSITE"</b> allows <b>multiply_region()</b> to recursively call <b>multiply_

+There is support for performing <b>multiply()</b> inline for the <b>"TABLE"</b> implementations for w &#8712 {4, 8} and for the

+by <b>multiply_region()</b> if you are not using <b>"ALTMAP."</b> To demonstrate this, in the table below, you can see that the
+performance of <b>multiply()</b> with <b>"SPLIT 8 4"</b> is 88 percent as fast than the default in <em>w</em> = 8 (which is <b>"TABLE"</b>).
+When you use each as a base field for <b>"COMPOSITE"</b> with <em>w</em> = 16, the one with <b>"SPLIT 8 4"</b> is now just 37 percent
+as fast. The difference is the inlining of multiplication in the base field when <b>"TABLE"</b> is employed:</p><br><br>

+<h2>7.7 &nbsp &nbsp &nbsp "CARRY_FREE" and the Primitive Polynomial </h2>
+
+
+If your machine supports the PCLMUL instruction, then we leverage that in <b>"CARRY_FREE."</b> This implementation
+first performs a carry free multiplication of two <em>w</em>-bit numbers, which yields a 2<em>w</em>-bit number. It does this with
+one PCLMUL instruction. To reduce the 2<em>w</em>-bit number back to a <em>w</em>-bit number requires some manipulation of the
+polynomial. As it turns out, if the polynomial has a lot of contiguous zeroes following its leftmost one, the number of
+reduction steps may be minimized. For example, with <em>w </em> = 32, we employ the polynomial 0x100400007, because that
+is what other libraries employ. This only has 9 contiguous zeros following the one, which means that the reduction
+takes four steps. If we instead use 0x1000000c5, which has 24 contiguous zeros, the reduction takes just two steps.
+You can see the difference in performance:

+<h2>7.8 &nbsp More on Primitive Polynomials </h3>

+<h3>7.8.1 &nbsp Primitive Polynomials that are not Primitive </h4>
+
+The library is willing to work with most polynomials, even if they are not primitive or irreducible. For example, the
+polynomial x<sup>4</sup> + x<sup>3</sup> +x<sup>2</sup> +x+1 is irreducible, and therefore generates a valid Galois Field for <em>GF(2<sup>4</sup>).</em> However, it
+is not primitive, because 2<sup>5</sup> = 1. For that reason, if you use this polynomial, you cannot use the <b>"LOG"</b> method. The
+other methods will work fine: <br><br>

+Division is a best effort service. The problemis that often quotients are not unique. If <b>divide()</b> returns a non-zero
+number, then that number will be a valid quotient, but it may be one of many. If the multiplication technique is
+<b>"TABLE,"</b> then if a quotient exists, one is returned. Otherwise, zero is returned. Here are some examples - the
+polynomial x<sup>4</sup> + 1 is reducible, and therefore produces a ring. Below, we see that with this polynomal, 1*6 = 6
+and 14*6 = 6. Therefore, 6/6 has two valid quotients: 1 and 14. GF-Complete returns 14 as the quotient:</li><br>

+
+<li>When <b>"EUCLID"</b> is employed for division, it uses the extended Euclidean algorithm for GCD to find a number's

+<h3>7.8.3 The Program gf_poly for Verifying Irreducibility of Polynomials </h3>
+
+The program <b>gf_poly</b> uses the Ben-Or algorithm[GP97] to determine whether a polynomial with coefficients in <em> GF(2<sup>w </sup>) </em>
+is reducible. Its syntax is:<br><br>
+<div id="number_spacing">
+gf_poly w method power:coef power:coef ...
+</div>
+
+<br>
+<p>You can use it to test for irreducible polynomials with binary coefficients by specifying w = 1. For example, from
+the discussion above, we know that x<sup>4</sup> +x+1 and x<sup>4</sup> +x<sup>3</sup> +x<sup>2</sup> +x+1 are both irreducible, but x<sup>4</sup> +1 is reducible.
+<b>gf_poly</b> confirms:<p><br>

+
+
+<p>
+For composite fields <em>GF((2<sup>l</sup>)<sup>2</sup>),</em> we are looking for a value s such that x<sup>2</sup> + sx + 1 is irreducible. That value
+depends on the base field. For example, for the default field <em>GF(2<sup>32</sup>),</em> a value of <em>s</em> = 2 makes the polynomial
+irreducible. However, if the polynomial 0xc5 is used (so that PCLMUL is fast - see section 7.7), then <em>s</em> = 2 yields a
+reducible polynomial, but <em>s</em> = 3 yields an irreducible one. You can use <b>gf_poly</b> to help verify these things, and to help
+define s if you need to stray from the defaults:</p> <br>

+<b>gf_unit</b> does random sampling to test for problems. In particular, it chooses a random a and a random b, multiplies
+them, and then tests the result by dividing it by a and b. When w is large, this sampling does not come close to
+providing complete coverage to check for problems. In particular, if the polynomial is reducible, there is a good
+chance that <b>gf_unit</b> won't discover any problems. For example, the following <b>gf_unit</b> call does not flag any problems,
+even though the polynomial is reducible.</p>

+<p>
+How can we demonstrate that this particular field has a problem? Well, when the polynomial is 0xc5, we can factor
+x<sup>2</sup> + 2x + 1 as (x + 0x7f6f95f9)(x + 0x7f6f95fb). Thus, in the composite field, when we multiply 0x17f6f95f9 by
+0x17f6f95fb, we get zero. That's the problem:

+<h2>7.9 "ALTMAP" considerations and extract_word() </h2>
+
+There are two times when you may employ alternate memory mappings:
+<ol>
+<li> When using <b>"SPLIT"</b> and w<sub>b</sub> = 4. </li>
+<li> When using <b>"COMPOSITE."</b> </li>
+</ol>
+
+Additionally, by default, the <b>"CAUCHY"</b> region option also employs an alternate memory mapping.
+
+<p>When you use alternate memory mappings, the exact mapping of words in <em> GF(2<sup>w </sup>) </em> to memory depends on the
+situation, the size of the region, and the alignment of the pointers. To help you figure things out, we have included the
+procedures <b>extract_word.wxx()</b> as part of the <b>gf_t</b> struct. This procedure takes four parameters: </p>
+<ul>
+<li>A pointer to the <b>gf_t.</b> </li>
+<li> The beginning of the memory region. </li>
+<li>The number of bytes in the memory region. </li>
+<li>The desired word number: <em>n.</em> </li>
+</ul>
+
+<p>
+It then returns the <em>n</em>-th word in memory. When the standard mapping is employed, this simply returns the <em>n</em>-
+th contiguous word in memory. With alternate mappings, each word may be split over several memory regions, so
+<b>extract_word()</b> grabs the relevant parts of each memory region to extract the word. Below, we go over each of the
+above situations in detail. Please refer to Figure 2 in Section 5 for reference. </p>
+
+
+<h3>7.9.1 Alternate mappings with "SPLIT" </h3>
+
+The alternate mapping with <b>"SPLIT"</b> is employed so that we can best leverage <b>mm_shuffle_epi8().</b> Please read [PGM13b]
+for details as to why. Consider an example when <em>w</em> = 16. In the main region of memory (the middle region in Figure
+2), multiplication proceeds in units of 32 bytes, which are each broken into two 16-byte regions. The first region
+holds the high bytes of each word in <em>GF(2<sup>16</sup>),</em> and the second region holds the low bytes.
+Let's look at a very detailed example, from <b>gf_example_5.c.</b> This program makes the following call, where <b>gf</b> has
+
+been initialized for <em>w</em> = 16, using <b>"SPLIT"</b> and <b>"ALTMAP:"</b><br><br>
+<div id="number_spacing">
+gf.multiply_region.w32(&gf, a, b, 0x1234, 30*2, 0);
+</div><br>
+
+
+<p>In other words, it is multiplying a region a of 60 bytes (30 words) by the constant 0x1234 in <em> GF(2<sup>16</sup>),</em> and placing
+the result into <em>b.</em> The pointers <em>a</em> and <em>b</em> have been set up so that they are not multiples of 16. The first line of output
+prints <em>a</em> and <em>b:</em></p><br>
+
+a: 0x10010008c b: 0x10010015c <br><br>
+
+As described in Section 5, the regions of memory are split into three parts:
+
+
+
+
+
+
+
+
+<br/>

+<li> 4 bytes starting at 0x1001008c / 0x10010015c. </li>
+<li> 32 bytes starting at 0x10010090 / 0x100100160. </li>
+<li> 24 bytes starting at 0x100100b0 / 0x100100180. </li>
+
+</ol>
+
+
+<p>In the first and third parts, the bytes are laid out according to the standard mapping. However, the second part is
+split into two 16-byte regions- one that holds the high bytes of each word and one that holds the low bytes. To help
+illustrate, the remainder of the output prints the 30 words of <em>a</em> and <em>b</em> as they appear in memory, and then the 30 return
+values of <b>extract_word.w32():</b> </p><br>

+In the first region are words 0 and 1, which are identical to how they appear in memory: 0x640b and 0x07e5. In
+the second region are words 2 through 17. These words are split among the two sixteen-byte regions. For example,
+word 2, which <b>extract_word()</b> reports is 0xba59, is constructed from the low byte in word 2 (0xba) and the low byte
+in word 10 (0x59). Since 0xba59 * 0x1234 = 0xf827, we see that the low byte in word 2 of <em> b </em> is 0xf8, and the low byte
+in word 10 is 0x27.
+<p>When we reach word 22, we are in the third region of memory, and words are once again identical to how they

+

+different alignments, or with different region sizes, then the results will not be consistent. To reiterate, if you don't use
+<b>ALTMAP,</b> you don't have to worry about any of this - words will always be laid out contiguously in memory.
+<p>
+When <em>w</em> = 32, the middle region is a multiple of 64, and each word in the middle region is broken into bytes, each
+of which is in a different 16-byte region. When <em>w</em> = 64, the middle region is a multiple of 128, and each word is
+stored in eight 16-byte regions. And finally, when<em>w</em> = 128, the middle region is a multiple of 128, and each word is
+stored in 16 16-byte regions.</p><br>
+
+<h3>7.9.2 &nbsp Alternate mappings with "COMPOSITE" </h3>
+
+With <b>"COMPOSITE,"</b> the alternate mapping divides the middle region in half. The lower half of each word is stored
+in the first half of the middle region, and the higher half is stored in the second half. To illustrate, gf_example_6
+performs the same example as gf_example_5, except it is using <b>"COMPOSITE"</b> in GF((2<sup>16</sup>)<sup>2</sup>), and it is multiplying
+a region of 120 bytes rather than 60. As before, the pointers are not aligned on 16-bit quantities, so the region is broken
+into three regions of 4 bytes, 96 bytes, and 20 bytes. In the first and third region, each consecutive four byte word is a
+word in <em>GF(2<sup>32</sup>).</em> For example, word 0 is 0x562c640b, and word 25 is 0x46bc47e0. In the middle region, the low two
+bytes of each word come from the first half, and the high two bytes come from the second half. For example, word 1
+as reported by <b>extract_word()</b> is composed of the lower two bytes of word 1 of memory (0x07e5), and the lower two
+bytes of word 13 (0x3fde). The product of 0x3fde07e5 and 0x12345678 is 0x211c880d, which is stored in the lower
+two bytes of words 1 and 13 of <em>b.</em><br><br>

+
+<h3>7.9.3 The mapping of "CAUCHY" </h3>
+
+With <b>"CAUCHY,"</b> the region is partitioned into <em>w</em> subregions, and each word in the region is broken into <em>w</em> bits,
+each of which is stored in a different subregion. To illustrate, <b>gf_example_7</b> multiplies a region of three bytes by 5
+in <em>GF(2<sup>3</sup>)</em> using <b>"CAUCHY:"</b><br><br>

+Word 6: 2 * 5 = 1 <br>
+Word 7: 6 * 5 = 3 <br>
+UNIX><br><br> </div>
+<p>
+
+The program prints the three bytes of a and b in hexadecimal and in binary. To see how words are broken up,
+consider word 0, which is the lowest bit of each of the three bytes of a (and b). These are the bits 1, 1 and 0 in a, and
+0, 0, and 1 in b. Accordingly, the word is 3 in a, and 3*5 = 4 in b. Similarly, word 7 is the high bit in each byte: 0, 1, 1
+(6) in a, and 1, 1, 0 (3) in b.</p>
+<p>With <b>"CAUCHY," multiply_region()</b>may be implemented exclusively with XOR operations. Please see [BKK<sup>+</sup>95]
+for more information on the motivation behind <b>"CAUCHY."</b> </p>
+
+<h2>8 &nbsp Thread Safety </h2>
+
+Once you initialize a <b>gf_t,</b> you may use it wontonly in multiple threads for all operations except for the ones below.
+With the implementations listed below, the scratch space in the <b>gf_t</b> is used for temporary tables, and therefore you
+cannot call <b>region_multiply,</b> and in some cases <b>multiply</b> from multiple threads because they will overwrite each
+others' tables. In these cases, if you want to call the procedures from multiple threads, you should allocate a separate
+gf_t for each thread:
+<ul>
+<li>
+ All "GROUP" implementations are not thread safe for either <b>region_multiply()</b> or <b> multiply().</b> Other than
+<b>"GROUP," multiply() </b> is always thread-safe.

+PCLMUL instructions. This issue can be fixed by installing an alternative compiler; see Section 3 for details</li><br>
+
+<li> <b>Initialization segfaults.</b> You have to already have allocated your <b>gf_t</b> before you pass a pointer to it in
+<b>bgf_init_easy()</b>, <b>create_gf_ from_argv()</b>, or <b>bgf_ini_hard()</b></li><br>
+
+

+<li><b>Incompatible division types.</b> Some choices of multiplication type constrain choice of divide type. For example,
+<b>"COMPOSITE"</b> methods only allow the default division type, which divides by finding inverses (i.e.,
+neither <b>"EUCLID"</b> nor <b>"MATRIX"</b> are allowed). For each multiplication method printed by <b>gf_methods.c,</b> the

+
+<li> <b>No default polynomial.</b> If you change the polynomial in a base field using <b>"COMPOSITE,"</b> then unless it is

+
+<li> <b>I used "ALTMAP" and it doesn't appear to be functioning correctly.</b> With 7.9, the size of the region and

+that for w &#8712 {4, 8, 16}, it is very fast indeed. For the other implementations, division is implemented with Euclid's
+method, and is several factors slower than multiplication.
+In Figure 6, we plot the speed of a few implementations of the larger word sizes. Compared to the <b>"TABLE"</b> and
+<b>"LOG"</b> implemenations for the smaller word sizes, where the speeds are in the hundreds of mega-ops per second,
+these are very slow. Of note is the <b>"COMPOSITE"</b> implementation for <em>w</em> = 32, which is much faster than the others

+
+because it uses a special application of Euclid's method, which relies on division in <em>GF(2<sup>16</sup>),</em> which is very fast.<br><br>
+
+<h3>11.3 &nbsp Multiply_Region() </h2>
+
+Tables 3 through 8 show the performance of the various region operations. It should be noted that for <em>GF(2<sup>16 </sup>) </em>
+through <em>GF(2<sup>128</sup>),</em> the default is not the fastest implementation of <b>multiply_region().</b> The reasons for this are outlined
+in section 6
+<p>
+For these tables, we performed 1GB worth of <b>multiply_region()</b> calls for all regions of size 2i bytes for 10 &#8804 i &#8804
+30. In the table, we plot the fastest speed obtained.</p>
+<p>We note that the performance of <b>"CAUCHY"</b> can be improved with techniques from [LSXP13] and [PSR12].</p>

+/* JSP - The purpose of this procedure is to error check alignment,
+ and to set up the region operation so that it can best leverage
+ large words.
+
+ It stores its information in rd.
+
+ Assuming you're not doing Cauchy coding, (see below for that),
+ then w will be 4, 8, 16, 32 or 64. It can't be 128 (probably
+ should change that).
+
+ src and dest must then be aligned on ceil(w/8)-byte boundaries.
+ Moreover, bytes must be a multiple of ceil(w/8). If the variable
+ align is equal to ceil(w/8), then we will set s_start = src,
+ d_start = dest, s_top to (src+bytes) and d_top to (dest+bytes).
+ And we return -- the implementation will go ahead and do the
+ multiplication on individual words (e.g. using discrete logs).
+
+ If align is greater than ceil(w/8), then the implementation needs
+ to work on groups of "align" bytes. For example, suppose you are
+ implementing BYTWO, without SSE. Then you will be doing the region
+ multiplication in units of 8 bytes, so align = 8. Or, suppose you
+ are doing a Quad table in GF(2^4). You will be doing the region
+ multiplication in units of 2 bytes, so align = 2. Or, suppose you
+ are doing split multiplication with SSE operations in GF(2^8).
+ Then align = 16. Worse yet, suppose you are doing split
+ multiplication with SSE operations in GF(2^16), with or without
+ ALTMAP. Then, you will be doing the multiplication on 256 bits at
+ a time. So align = 32.
+
+ When align does not equal ceil(w/8), we split the region
+ multiplication into three parts. We are going to make s_start be
+ the first address greater than or equal to src that is a multiple
+ of align. s_top is going to be the largest address >= src+bytes
+ such that (s_top - s_start) is a multiple of align. We do the
+ same with d_start and d_top. When we say that "src and dest must
+ be aligned with respect to each other, we mean that s_start-src
+ must equal d_start-dest.
+
+ Now, the region multiplication is done in three parts -- the part
+ between src and s_start must be done using single words.
+ Similarly, the part between s_top and src+bytes must also be done
+ using single words. The part between s_start and s_top will be
+ done in chunks of "align" bytes.
+
+ One final thing -- if align > 16, then s_start and d_start will be
+ aligned on a 16 byte boundary. Perhaps we should have two
+ variables: align and chunksize. Then we'd have s_start & d_start
+ aligned to "align", and have s_top-s_start be a multiple of
+ chunksize. That may be less confusing, but it would be a big
+ change.
+
+ Finally, if align = -1, then we are doing Cauchy multiplication,
+ using only XOR's. In this case, we're not going to care about
+ alignment because we are just doing XOR's. Instead, the only
+ thing we care about is that bytes must be a multiple of w.
+
+ This is not to say that alignment doesn't matter in performance
+ with XOR's. See that discussion in gf_multby_one().
+
+ After you call gf_set_region_data(), the procedure
+ gf_do_initial_region_alignment() calls gf->multiply.w32() on
+ everything between src and s_start. The procedure
+ gf_do_final_region_alignment() calls gf->multiply.w32() on
+ everything between s_top and src+bytes.

+ *
+ * gf_poly.c - program to help find irreducible polynomials in composite fields,
+ * using the Ben-Or algorithm.
+ *
+ * (This one was written by Jim)
+ *
+ * Please see the following paper for a description of the Ben-Or algorithm:
+ *
+ * author S. Gao and D. Panario
+ * title Tests and Constructions of Irreducible Polynomials over Finite Fields
+ * booktitle Foundations of Computational Mathematics
+ * year 1997
+ * publisher Springer Verlag
+ * pages 346-361
+ *
+ * The basic technique is this. You have a polynomial f(x) whose coefficients are
+ * in a base field GF(2^w). The polynomial is of degree n. You need to do the
+ * following for all i from 1 to n/2:
+ *
+ * Construct x^(2^w)^i modulo f. That will be a polynomial of maximum degree n-1
+ * with coefficients in GF(2^w). You construct that polynomial by starting with x
+ * and doubling it w times, each time taking the result modulo f. Then you
+ * multiply that by itself i times, again each time taking the result modulo f.
+ *
+ * When you're done, you need to "subtract" x -- since addition = subtraction =
+ * XOR, that means XOR x.
+ *
+ * Now, find the GCD of that last polynomial and f, using Euclid's algorithm. If
+ * the GCD is not one, then f is reducible. If it is not reducible for each of
+ * those i, then it is irreducible.
+ *
+ * In this code, I am using a gf_general_t to represent elements of GF(2^w). This
+ * is so that I can use base fields that are GF(2^64) or GF(2^128).
+ *
+ * I have two main procedures. The first is x_to_q_to_i_minus_x, which calculates
+ * x^(2^w)^i - x, putting the result into a gf_general_t * called retval.
+ *
+ * The second is gcd_one, which takes a polynomial of degree n and a second one
+ * of degree n-1, and uses Euclid's algorithm to decide if their GCD == 1.
+ *
+ * These can be made faster (e.g. calculate x^(2^w) once and store it).

+This program takes as input an inputfile, k, m, a coding
+technique, w, and packetsize. It is the companion program
+of encoder.c, which creates k+m files. This program assumes
+that up to m erasures have occurred in the k+m files. It
+reads in the k+m files or marks the file as erased. It then
+recreates the original file and creates a new file with the
+suffix "decoded" with the decoded contents of the file.
+
+This program does not error check command line arguments because
+it is assumed that encoder.c has been called previously with the
+same arguments, and encoder.c does error check.

+Installation Instructions
+*************************
+

+without warranty of any kind.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an

+\`configure' configures Jerasure 2.0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a

+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if

+ i of the survivors vector. I.e. row i of the decoding matrix
+ times dm_ids equals data drive i.

+# SYNOPSIS

+# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])
+#
+# DESCRIPTION
+#
+# Check whether the given FLAG works with the current language's compiler
+# or gives an error. (Warnings, however, are ignored)
+#
+# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
+# success/failure.
+#
+# If EXTRA-FLAGS is defined, it is added to the current language's default
+# flags (e.g. CFLAGS) when the check is done. The check is thus made with
+# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
+# force the compiler to issue an error when a bad flag is given.
+#
+# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
+# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

+# AX_GCC_X86_AVX_XGETBV
+#
+# DESCRIPTION
+#
+# On later x86 processors with AVX SIMD support, with gcc or a compiler
+# that has a compatible syntax for inline assembly instructions, run a
+# small program that executes the xgetbv instruction with input OP. This
+# can be used to detect if the OS supports AVX instruction usage.
+#
+# On output, the values of the eax and edx registers are stored as
+# hexadecimal strings as "eax:edx" in the cache variable
+# ax_cv_gcc_x86_avx_xgetbv.
+#
+# If the xgetbv instruction fails (because you are running a
+# cross-compiler, or because you are not using gcc, or because you are on
+# a processor that doesn't have this instruction),
+# ax_cv_gcc_x86_avx_xgetbv_OP is set to the string "unknown".
+#
+# This macro mainly exists to be used in AX_EXT.

+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
