A Judy array is referred to here as an "SM", rather +// than as a "tree"; having "states", rather than "levels". +// +// Each branch or leaf in the SM decodes a portion ("digit") of the original +// Index; with 256-way branches there are 8 bits per digit. There are 3 kinds +// of branches, called: Linear, Bitmap and Uncompressed, of which the first 2 +// are compressed to contain no NULL entries. +// +// An Uncompressed branch has a 1.0 cache line fill cost to decode 8 bits of +// (digit, part of an Index), but it might contain many NULL entries, and is +// therefore inefficient with memory if lightly populated. +// +// A Linear branch has a ~1.75 cache line fill cost when at maximum population. +// A Bitmap branch has ~2.0 cache line fills. Linear and Bitmap branches are +// converted to Uncompressed branches when the additional memory can be +// amortized with larger populations. Higher-state branches have higher +// priority to be converted. +// +// Linear branches can hold 28 elements (based on detailed analysis) -- thus 28 +// expanses. A Linear branch is converted to a Bitmap branch when the 29th +// expanse is required. +// +// A Bitmap branch could hold 256 expanses, but is forced to convert to an +// Uncompressed branch when 185 expanses are required. Hopefully, it is +// converted before that because of population growth (again, based on detailed +// analysis and heuristics in the code). +// +// A path through the SM terminates to a leaf when the Index (or key) +// population in the expanse below a pointer will fit into 1 or 2 cache lines +// (~31..255 Indexes). A maximum-population Leaf has ~1.5 cache line fill +// cost. +// +// Leaves are sorted arrays of Indexes, where the Index Sizes (IS) are: 0, 1, +// 8, 16, 24, 32, [40, 48, 56, 64] bits. The IS depends on the "density" +// (population/expanse) of the values in the Leaf. Zero bits are possible if +// population == expanse in the SM (that is, a full small expanse). +// +// Elements of a branches are called Judy Pointers (JPs). Each JP object +// points to the next object in the SM, plus, a JP can decode an additional +// 2[6] bytes of an Index, but at the cost of "narrowing" the expanse +// represented by the next object in the SM. A "narrow" JP (one which has +// decode bytes/digits) is a way of skipping states in the SM. +// +// Although counterintuitive, we think a Judy SM is optimal when the Leaves are +// stored at MINIMUM compression (narrowing, or use of Decode bytes). If more +// aggressive compression was used, decompression of a leaf be required to +// insert an index. Additional compression would save a little memory but not +// help performance significantly. + + +#ifdef A_PICTURE_IS_WORTH_1000_WORDS +******************************************************************************* + +JUDY 32-BIT STATE MACHINE (SM) EXAMPLE, FOR INDEX = 0x02040103 + +The Index used in this example is purposely chosen to allow small, simple +examples below; each 1-byte "digit" from the Index has a small numeric value +that fits in one column.
