| title | Is there a way to switch back from PMIx to PMI-2 with srun? |
|---|
|
Yes. Simply say unset I_MPI_PMI_LIBRARY and export SLURM_MPI_TYPE=pmi2 before invoking srun. (Be prepared that problems arise from this for binaries linked against Open MPI 5.x.) |

| title | Why do I receive "MPI startup(): Warning: I_MPI_PMI_LIBRARY will be ignored since the hydra process manager was found"? |
|---|
|
This is because we need to define I_MPI_PMI_LIBRARY to ensure that the PMIx interface of srun works also for Intel-MPI. Obviously, you prefer mpirun over srun, and in this case you can manually unset I_MPI_PMI_LIBRARY to avoid this (harmless) warning message. |
