Benchmarks

The features benchmarked for performance tracking are tested on multiple platforms and instructions to perform standard build and tests are gathered here as they are common to all benchmarks. If a particular kernel needs specific settings to be benchmarked, it will be specified on the kernel benchmark page.

KNL setup (Bowman)

1. Set up Kokkos

You can use the latest version of Kokkos. The experiments of the paper "Multi-threaded Sparse Matrix-Matrix Multiplication for Many-Core and GPU Architectures" uses kokkos-version: 2.04.04

mkdir $HOME/kokkoskernels_spgemm_benchmark
cd $HOME/kokkoskernels_spgemm_benchmark
git clone [email protected]:kokkos/kokkos.git

2. Get KokkosKernels

cd $HOME/kokkoskernels_spgemm_benchmark
git clone [email protected]:kokkos/kokkos-kernels.git

Currently KokkosKernels-spgemm updates are not on the master branch yet (12/20/2017). Checkout the develop branch.

cd $HOME/kokkoskernels_spgemm_benchmark/kokkos-kernels
git checkout develop

3. Update the compileKokkosKernels.sh located at example/buildlib.

cd $HOME/kokkoskernels_spgemm_benchmark/kokkos-kernels/example/buildlib
vi compileKokkosKernels.sh

Below is the example of compileKokkosKernels.sh for KNLs.

KOKKOS_PATH=${HOME}/kokkoskernels_spgemm_benchmark/kokkos #path to kokkos source
KOKKOSKERNELS_SCALARS='double' #we only need double
KOKKOSKERNELS_LAYOUTS=LayoutLeft #the layout types to instantiate.
KOKKOSKERNELS_ORDINALS=int #ordinal types to instantiate
KOKKOSKERNELS_OFFSETS=int #offset types to instantiate
KOKKOSKERNELS_PATH=${HOME}/kokkoskernels_spgemm_benchmark/kokkos-kernels #path to kokkos-kernels top directory.
KOKKOSKERNELS_OPTIONS=eti-only #options for kokkoskernels  
CXXFLAGS="-Wall -pedantic -Werror -O3 -g -Wshadow -Wsign-compare -Wignored-qualifiers -Wempty-body -Wclobbered -Wuninitialized"
CXX=icpc
KOKKOS_DEVICES=OpenMP #we only need openmp execution space.
KOKKOS_ARCHS=KNL        #!!!!!!!!!!!!!!!!!!specify the architecture for compilation!!!!!!!!!!!!!!!!!!!
KOKKOSKERNELS_TPLS=mkl #if you want to be able to run mkl functionalities as well. otherwise place "".

../../scripts/generate_makefile.bash --kokkoskernels-path=${KOKKOSKERNELS_PATH} --with-scalars=${KOKKOSKERNELS_SCALARS} --with-ordinals=${KOKKOSKERNELS_ORDINALS} --with-offsets=${KOKKOSKERNELS_OFFSETS} --kokkos-path=${KOKKOS_PATH} --with-devices=${KOKKOS_DEVICES} --arch=${KOKKOS_ARCHS} --compiler=${CXX} --with-options=${KOKKOSKERNELS_OPTIONS}  --cxxflags="${CXXFLAGS}" --with-tpls=${KOKKOSKERNELS_TPLS}

Set the compiler. If you use mkl, export the mkl path.

module load intel/compilers/18.0.128
export MKL_PATH=/home/projects/x86-64-knl/intel/beta/pstudio/2018-B1/compilers_and_libraries_2018.0.061/linux/mkl/

4. Compile KokkosKernels.

cd $HOME/kokkoskernels_spgemm_benchmark/kokkos-kernels/example/buildlib
./compileKokkosKernels.sh
make build-test -j
