Use the spack package manager to load the desired combination of Kokkos, gcc, and Cuda
spack load kokkos%gcc@12 +cuda
Enter the desired example or problem folder and run:
KOKKOS_DEVICES=Cuda make
This sets up all of the sources files.
To run the final executables:
LD_LIBRARY_PATH=$(spack location -i cuda@12)/lib64 ./program_name.cuda
To use without Cuda, you will want to load the Cuda-less Kokkos packages
spack load kokkos%gcc@12 ~cuda
Run these inside the desired example or problem
KOKKOS_DEVICES=OpenMP make
./program_name.host
Do the above steps for, but also load OpenMPI with,
spack load [email protected]%gcc@=8.5.0 arch=linux-rocky8-x86_64_v3
Make as normal
To run MPI+Kokkos
mpirun -n 2 ./prog.host
