[slurm-users] Intel MPI startup

They (Intel) told me to use PMI-1. We set I_MPI_PMI_LIBRARY=<path_to_slurm_libs>/libpmi.so and it works fine, but if we set

I_MPI_PMI_LIBRARY=<path_to_slurm_libs>/libpmi2.so it fails to start. I have not gone down the road of doing anything with PMIx yet. Waiting for it to mature a little more.

Intel has supposedly supported PMI-2 since their 2017 release and that
is what SchedMD suggested we use in a recent bug report to them, but I
found that it no longer works in Intel MPI 2019. I opened a bug report
with Intel on what appears to be an undocumented regression and all I
got after several back and forths was that PMI-2 is not supported in
Intel MPI 2019.

Is that because they've moved to PMIx exclusively now?

All the best,
