[slurm-users] PMIX and slurm failure (and fix).

[Artem Polyakov]

Thank you Bill.

Can you provide anonymized Slurm.conf (I mainly interested in auth
setting), srun launch error and config.log where you saw libssl mention.

Being PMIx plugin developer I’m not aware about any explicit dependencies
from libssl in Slurm. Only thing I can think of would be authentication
service that can be either munge or libssl. But this is a generic service
and one would notice it elsewhere if not with PMIx.

It might be a dependency of PMIx library, though I’d guess that it should
be able to work without it.
