Thank you Satish and Junchao! I was able to compile PETSc with your configure options + suitesparse and hypre, and then compile my fortran code linking to PETSc. But when I try to run my test run I'm picking up an error at the very beginning:
MPICH ERROR [Rank 0] [job id 01eb3c4a-28a7-4178-aced-512b4fb704c6] [Thu May 2 20:44:26 2024] [x3006c0s19b1n0] - Abort(-1) (rank 0 in comm 0): MPIDI_CRAY_init: GPU_SUPPORT_ENABLED is requested, but GTL library is not linked (Other MPI error) aborting job: MPIDI_CRAY_init: GPU_SUPPORT_ENABLED is requested, but GTL library is not linked It says in the Polaris user guide that: The environment variable MPICH_GPU_SUPPORT_ENABLED=1 needs to be set if your application requires MPI-GPU support whereby the MPI library sends and receives data directly from GPU buffers. In this case, it will be important to have the craype-accel-nvidia80 module loaded both when compiling your application and during runtime to correctly link against a GPU Transport Layer (GTL) MPI library. Otherwise, you'll likely see GPU_SUPPORT_ENABLED is requested, but GTL library is not linked errors during runtime. I tried adding loading this module (also needed to add nvhpc-mixed) in my submission script but I get the same result. I'll get in touch with alcf help on this. ________________________________ From: Satish Balay <[email protected]> Sent: Thursday, May 2, 2024 11:58 AM To: Junchao Zhang <[email protected]> Cc: petsc-users <[email protected]>; Vanella, Marcos (Fed) <[email protected]>; Mueller, Eric V.
