# Need to load additional rocm module to build with hip
#
# module load rocm/5.1.0
#
# We use Cray Programming Environment, Cray compilers, Cray-mpich.
# To enable GPU-aware MPI, one has to also set this runtime environment variable
#
# export MPICH_GPU_SUPPORT_ENABLED=1
#
# Additional note: "craype-accel-amd-gfx90a" module is recommended for
# "OpenMP offload" or "GPU enabled MPI". It requires "--with-openmp" option.
# [otherwise building c examples gives link errors (when fortran bindings are enabled)]
# Alternative is to use "-lmpi_gtl_hsa" as used below.
