Hans Jørgen Aa. Jensen informed me that IBM colleagues at the Summit workshop recommended to change -qsmp
to -qsmp=omp
in CMAKE_Fortran_COMPILER_ID
. If you want to also enable the new OpenMP 4.5+ features to off-load to a GPU from OpenMP in XL Fortran, one should specify "-qsmp=omp -qoffload".

I think we should for the moment keep the -qoffload
as an extra flag.
