Description
Suggestion Description
Hello,
During some experiments with MPICH, we found out that the run_rochpl wrapper only supports Open MPI, slurm or flux. The following lines are responsible for this :
https://github.com/ROCm/rocHPL/blob/d76d0c3ba9a75ff40a782a33d69760e3d9c7ed1f/scripts/run_rochpl.in#L196-L214
We implemented a small patch that adds support for MPICH and MVAPICH :
Fell free to add it.
You could even integrate other launcher (see for instance what's done in hpcbind from kokkos :https://github.com/kokkos/kokkos/blob/develop/bin/hpcbind#L93-L121)
Best,
Antoine.

Research direction
Start in scripts/run_rochpl.in at lines 196-214 and review the attached mpisupport.patch for the proposed MPICH and MVAPICH handling. Compare the launcher selection approach with kokkos/bin/hpcbind, then verify that run_rochpl supports the added launchers while retaining Open MPI, Slurm, and Flux support.
