setup

git clone https://github.com/SCOREC/polyMpmTest.git

build

The following assumes that a valid C and C++ compiler, and cmake, are in your PATH.

CMAKE_INSTALL_PREFIX is the path where the library, headers, and test binary are installed.

kk is the path where kokkos is installed (either GPU or OpenMP based installation).

Set path as export kk=/path/to/kokkos/install

kk_compiler is the path to kokkos compiler Set path as export kk_compiler=/path/to/nvcc_wrapper for GPU build.

Ignore this for OpenMP build

Load necessary modules:

module unuse /opt/scorec/spack/lmod/linux-rhel7-x86_64/Core
module use /opt/scorec/spack/v0154_2/lmod/linux-rhel7-x86_64/Core
module load \
gcc/10.1.0 \
openmpi \
cmake/3.20.0  \
cuda/11.4

Install Kokkos

Clone the repo

git clone https://github.com/Kokkos/kokkos.git

Create a file named installKokkos.sh with the following contents:

bkend=$1
d=buildKokkos${bkend}
omp=""
cuda=""
[[ ${bkend} == "OPENMP" ]] && omp="-DKokkos_ENABLE_OPENMP=on"
[[ ${bkend} == "CUDA" ]] && cuda="-DKokkos_ENABLE_CUDA=on -DKokkos_ENABLE_CUDA_LAMBDA=on"
[[ ${bkend} == "OPENMP_CUDA" ]] && ompcuda="-DKokkos_ENABLE_OPENMP=on -DKokkos_ENABLE_CUDA=on -DKokkos_ENABLE_CUDA_LAMBDA=on"
cmake -S kokkos -B $d \
  -DCMAKE_CXX_COMPILER=g++ \
  -DKokkos_ARCH_TURING75=ON \
  -DBUILD_SHARED_LIBS=ON \
  $omp \
  $cuda \
  $ompcuda \
  -DKokkos_ENABLE_SERIAL=ON \
  -DKokkos_ENABLE_DEBUG=on \
  -DKokkos_ENABLE_TESTS=off \
  -DCMAKE_INSTALL_PREFIX=$d/install
cmake --build $d -j 8 --target install

Make it executable:

chmod +x installKokkos.sh

Install with CUDA backend

./installKokkos.sh CUDA

Install with OpenMP backend

./installKokkos.sh OPENMP

Install with Serial backend

./installKokkos.sh

Building for GPU execution

Create a file named doConfigPolyMpmSheathGpu.sh with the following contents:

bdir=$PWD/build-GPU
cmake -S polyMpmTest -B $bdir \
-DKokkos_DIR=$PWD/buildKokkosCUDA/install/lib64/cmake/Kokkos \
-DCMAKE_CXX_COMPILER=$PWD/buildKokkosCUDA/install/bin/nvcc_wrapper \
-DCMAKE_INSTALL_PREFIX=$bdir/install

Create a file named buildPolyMpmSheathGpu.sh with the following contents:

bdir=$PWD/build-GPU
cmake --build $bdir --target install

Make them executable:

chmod +x doConfigPolyMpmSheathGpu.sh buildPolyMpmSheathGpu.sh

Run the configure script then run the build script:

./doConfigPolyMpmSheathGpu.sh
./buildPolyMpmSheathGpu.sh

To rebuild the code after making some changes:

./buildPolyMpmSheathGpu.sh

Building for CPU execution using OpenMP

Create a file named doConfigPolyMpmSheathOmp.sh with the following contents:

bdir=$PWD/build-omp
cmake -S polyMpmTest -B $bdir \
-DKokkos_DIR=$PWD/buildKokkosOPENMP/install/lib64/cmake/Kokkos \
-DCMAKE_INSTALL_PREFIX=$bdir/install

Create a file named buildPolyMpmSheathOmp.sh with the following contents:

bdir=$PWD/build-omp
cmake --build $bdir --target install

Make them executable:

chmod +x doConfigPolyMpmSheathOmp.sh buildPolyMpmSheathOmp.sh

Run the configure script then run the build script:

./doConfigPolyMpmSheathOmp.sh
./buildPolyMpmSheathOmp.sh

To rebuild the code after making some changes:

./buildPolyMpmSheathOmp.sh

Building for CPU execution using serial backend

Create a file named doConfigPolyMpmSheathSerial.sh with the following contents:

bdir=$PWD/build-omp
cmake -S polyMpmTest -B $bdir \
-DKokkos_DIR=$PWD/buildKokkosSerial/install/lib64/cmake/Kokkos \
-DCMAKE_INSTALL_PREFIX=$bdir/install

Create a file named buildPolyMpmSheathSerial.sh with the following contents:

bdir=$PWD/build-serial
cmake --build $bdir --target install

Make them executable:

chmod +x doConfigPolyMpmSheathSerial.sh buildPolyMpmSheathSerial.sh

Run the configure script then run the build script:

./doConfigPolyMpmSheathSerial.sh
./buildPolyMpmSheathSerial.sh

Run test

Run with [OpenMP|CUDA|Serial]

./build-[omp|GPU|serial]/test/testWachspress
