Marc Sarraute 8f8345b34a Manage GPU markers with compilation flag rather than input param 
GPU markers, such as NVTX (NVIDIA) or ROCtx (AMD) are meant to be used
for profiling purposes, along specific profiling tools (Nsight Systems,
Radeon profiler, Perfetto UI...).
As such, they are mostly used for development or benchmarking purposes
and aren't of any use for the end-user of ABINIT.

This commit changes the way one enables GPU Markers:
- input parameter "gpu_use_nvtx" is removed
- configure option "with_gpu_markers/--with-gpu-markers" is added
- CMake option "-DABINIT_ENABLE_GPU_MARKERS" is added

The way GPU markers were handled in ABINIT code doesn't change as this
feature was already hidden and protected by define HAVE_GPU_MARKERS.

Marc Sarraute 12f7e84425 Setup rocFFT at linalg_init 
We perform this init step here for the same reason as rocBLAS, that is
to not spend abnormal time on the first step when FFT is call for the
first time.

Marc Sarraute 72ca782322 [amdhip] CMake: add support for AMD HIP, Cray and LLVM

Marc Sarraute 263390046b Replace HAVE_GPU_NVTX_V3 with HAVE_GPU_MARKERS to generalize with other markers 2023-11-14 19:08:19 +01:00
Marc Sarraute d932a5283d cmake: replace "-fast" flag from CXX flags when using NVHPC 
CMake takes this flag in Release configuration and Kokkos uses it
through nvcc_wrapper that pass it to g++ which doesn't recognize this
flag and trigger an error.
"-fast" is usually "-O2" + extra flags so replacing it with "-O2" should
affect performance to much.

Marc Sarraute 1edbcd7cc7 Add support for OpenMP GPU offload flags in CMake 
For now, OpenMP GPU offload is always enabled if compiler succeeds the
test for checking OpenMP 5 compliance.

CMake doesn't have support for OpenMP target flags yet, hence I
copy-pasted a function that handles the job for many compilers through
only NVHPC is actually ABINIT-proofed for now.
