Running Kokkos programs with Cuda

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

Running Kokkos without 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
