Build and Run on Corona

Download

git clone git@github.com:SCOREC/omega_h.git
cd omega_h
git checkout clang11_hip

Create envCoronaRocm.sh with the following contents:

module load opt
module load rocm/3.6.0
module unload intel

Build for host using Clang11

source envCoronaClang11.sh
mkdir build-omega-clang11
cd !$
cmake ../omega_h \
  -DCMAKE_INSTALL_PREFIX=$PWD/install \
  -DBUILD_SHARED_LIBS=OFF \
  -DOmega_h_USE_HIP=OFF \
  -DOmega_h_USE_Kokkos=OFF \
  -DOmega_h_USE_MPI=OFF \
  -DCMAKE_CXX_COMPILER=/opt/rocm-3.6.0/llvm/bin/clang++ \
  -DOmega_h_CXX_WARNINGS=OFF \
  -DBUILD_TESTING=ON

make -j4
ctest # all tests should pass

Build for GPUs using hipcc

source envCoronaClang11.sh
mkdir build-omega-rocm36
cd !$
rocm=/opt/rocm-3.6.0
export HIP_PATH=$rocm/hip
export CMAKE_PREFIX_PATH=$rocm:$CMAKE_PREFIX_PATH
cmake ../omega_h \
  -DCMAKE_INSTALL_PREFIX=$PWD/install \
  -DBUILD_SHARED_LIBS=OFF \
  -DOmega_h_USE_HIP=ON \
  -DOmega_h_USE_Kokkos=OFF \
  -DCMAKE_CXX_FLAGS="--amdgpu-target=gfx906" \
  -DHIP_PATH=${rocm}/hip \
  -DOmega_h_USE_MPI=OFF \
  -DCMAKE_CXX_COMPILER=hipcc \
  -DOmega_h_CXX_WARNINGS=OFF \
  -DBUILD_TESTING=ON

make
