Benchmark collection to test task affinity implementation presented during IWOMP 2018

1. List of benchmarks tested

The following benchmarks have been tested with and without affinity extenstion for the OpenMP task construct.

  • ./stream
    • STREAM version that uses tasks instead of work sharing construct
  • ./bots/omp-tasks/sort
    • Parallel merge sort algorithm from bots benchmark suite
  • ./bots/omp-tasks/health
    • health benchmark from bots benchmark suite
  • ./sparse_CG/tasking
    • CG solver that uses SPMXV

2. How to compile and run

2.1 Clone repository that contains the customized runtime and switch to branch task-affinity

git clone git@github.com:jklinkenberg/openmp.git
cd openmp  
git checkout task-affinity

2.2 Move back to folder that contains openmp repo and clone this repository now

cd ..
git clone git@github.com:jklinkenberg/task-affinity-codes.git
cd task-affinity-codes

2.3 Set the following environment variables. Then build the runtime

export RUNTIME_AFF_REL_DIR=$(pwd)/runtime_affinity_rel
export RUNTIME_AFF_DEB_DIR=$(pwd)/runtime_affinity_deb
make

2.4 Set your C compiler either to intel or clang (Should be a compiler that is compatible with LLVM OpenMP runtime)

export CC=icc

2.5 Move to desired benchmark folder, e.g., stream and execute fast run, that will compare llvm basline with affinity versions

cd stream
sh fast_run.sh
