'make test' hangs vasp 6.4.3 nvhpc_omp_acc

[jaime_gutierrez]

Hello,

I've previously successfully compiled vasp 6.4.2 on an HPC cluster with nvhpc_omp_acc as well as nvhpc_omp where the 'make test' have passed.

I am now running into an issue with a new build of version 6.4.3 where the compilation completes, but the 'make test' hangs indefinitely, always at the same spot. I've attached the makefile.include as well as the stdout of the complilation and the 'make test'.

Best Regards,
Jaime

Hello,

nvhpc-24.9 + openmpi-3.3.10 is not a validated toolchain.
Can you please choose one from our validated toolchains.

Also, I suggest running with the same number of MPI ranks than GPUs available. This will improve performance and you get rid of following message while running vasp:

Code: Select all

 WARNING: INIT_ACC: several MPI-ranks need to share a GPU, which is not
     supported by NCCL. The use of NCCL will be switched off. To avoid this,
     reduce the number of MPI-ranks: #-of-ranks <= #-of-GPUs (on every node!).
