# dmclock
This repository contains C++ 11 code that implements the dmclock
distributed quality of service algorithm. See __mClock: Handling
Throughput Variability for Hypervisor IO Scheduling__ by Gulati,
Merchant, and Varman for a description of the algorithm.
## Running cmake
When running cmake, set the build type with either:
-DCMAKE_BUILD_TYPE=Debug
-DCMAKE_BUILD_TYPE=Release
To turn on profiling, run cmake with an additional:
-DPROFILE=yes
## Running make
### Building the dmclock library
The `make` command builds a library libdmclock.a. That plus the header
files in the src directory allow one to use the implementation in
their code.
### Building unit tests
The `make dmclock-tests` command builds unit tests.
### Building simulations
The `make dmclock-sims` command builds two simulations -- *dmc_sim*
and *ssched_sim* -- which incorporate, respectively, the dmclock
priority queue or a very simple scheduler for comparison. Other
priority queue implementations could be added in the future.
## dmclock API
To be written....
