Framework: psec warning

[ahkumar]

Dear all,

Setup:
I ran into the below warnings on an install, where I have slurm compiled against both pmix v3.2.2 & v4.2.3.
I am using: OpenMPI: 4.1.4 & slurm 22.05.08;

Issue: I don't see this warning if I chose to use --mpi=pmix_v3.

Question:

a) Any idea why do I see this?
b) Wondering if there is a way I can silence this warning?

Thank you!!

`# srun --mpi=pmix_v4 -n1 ./mpi_hello.slurm

A requested component was not found, or was unable to be opened. This
means that this component is either not installed or is unable to be
used on your system (e.g., sometimes this means that shared libraries
that the component requires are unable to be found/loaded). Note that
PMIx stopped checking at the first component that it did not find.

Slurm normally requires the munge library to make the client-server connections. In this case, Slurm and PMIx saw the munge library when built, but the library appears to be missing from the compute nodes where your process is running. You can tell PMIx to ignore that component by adding PMIX_MCA_psec=^munge to your environment.
