HIP updates

[MichaelSt98]

• adding arch files for LUMI CCE 16.0.1
• adding col/s as metric for HIP variants

Changes look sane to me, but I'll let @reuterbal check the LUMI configuration before merging. GTG from me though

[reuterbal]

Many thanks. HIP variants work perfectly as expected, and plain SCC still crashes the compiler, as expected.
But the OpenMP flags in the toolchain file aren't working for me as is. I've made a suggestion for a fix that I could build with successfully.

[reuterbal]

Isn't -maxrregcount 64 an NVHPC compiler option? It didn't work for me with CCE.
Also, there's the usual OpenMP library lookup failure that we know from IFS. The following options work, though:

	set( ENABLE_OMP ON CACHE STRING "" )
	set( OpenMP_C_FLAGS "-homp" CACHE STRING "" )
	set( OpenMP_Fortran_FLAGS "-homp -hnoacc -hlist=aimd -maxrregcount 64" CACHE STRING "" )

	# OpenACC FLAGS

	set( ENABLE_ACC ON CACHE STRING "" )
	set( OpenMP_C_FLAGS "-fopenmp" )
	set( OpenMP_CXX_FLAGS "-fopenmp" )
	set( OpenMP_Fortran_FLAGS "-fopenmp" )
	set( OpenMP_C_LIB_NAMES "craymp" )
	set( OpenMP_CXX_LIB_NAMES "craymp" )
	set( OpenMP_Fortran_LIB_NAMES "craymp" )
	set( OpenMP_craymp_LIBRARY "/opt/cray/pe/cce/16.0.1/cce/x86_64/lib/libcraymp.so" )

Thanks! I can confirm that all variants build now.

Unfortunately, the env file still doesn't quite work for me:

1. The import of cray-hdf5/1.12.2.3 is missing, which is required to build without Serialbox
2. somehow, none of the OpenACC or OpenMP offload variants seem to be offloading to GPU.

Would you mind fixing 1 and briefly investigating 2?

[reuterbal]

Thanks for figuring out the missing offload. Still some problems with the env file, at least when I've tried it, but a suggested solution that worked for me.

[MichaelSt98]

Just double-checked your proposed changes and committed them.
Thank you @reuterbal!

[reuterbal]

Perfect, many thanks. Going in
