Hey Marcus,
thank you very much for your quick answer.
I understand that, that I should upgrade DBD first, CTRL second and after
them the Node´s.
It make sense, if you read this Paper - but if you look at the HomePage,
there are no informations about that - so it is confused...
About OpenMPI:
Yes, I understand that SLURM want to disable old versions of
"OpenMPI - Standards", that makes sense.
But I think it was a good idea for SLURM, that they give us these
informations before they
want to disable that, so that we can check it in our
environment.
Best regards
.

HI,
to your first question: I don't know the exact reason, but SchedMD made it
pretty clear, that there is a spcific sequence for updates:
slurmdbd -> slurmctld -> slurmd -> commands See
https://slurm.schedmd.com/SLUG19/Field_Notes_3.pdf (or any of the other
field notes) for details.
So, I'd advise that you don't try it any other way.
for your second question, see https://slurm.schedmd.com/slurm.conf.html:
> MpiParams
> MPI parameters. Used to identify ports used by older versions of

> NOTE: This is require for Cray's PMI.
Best,
Marcus
