HI Matthias,
It looks like the Open MPI in the containers was not built with PMI1 or PMI2
support, so its defaulting to using PMIx.
You are seeing this error message because the call within Open MPI 4.1.x’s
runtime system to PMIx_Init returned an error.
Namely that there was no PMIx server to co
Thanks Christopher,
This doesn't seem to be related to Open MPI at all except that for our 5.0.0
and newer one has to use PMix to talk to the job launcher.
I built MPICH 4.1 on Perlmutter using the --with-pmix option and see a similar
message from srun --mpi=pmix

HI,
So I’m testing the use of Open MPI 5.0.0 pre-release with the Slurm/PMIx setup
currently on NERSC Perlmutter system.
First off, if I use the PRRte launch system, I don’t see the issue I’m raising
here.
But, many NERSC users prefer to use the srun “native” launch method with
applications co

to determine what that was/is.

Your use of the –with-pmix on the open mpi configure line is important.
Without any args to this configure option open mpi configure will first check

Hi Chris,
What’s happening is that there’s no SLURM_JOBID (my speculation since I don’t
have perms to use –no-alloc) is set, but SLURM_NODELIST may be set, so its
confusing ORTE.
Could you list which SLURM env variables are set in the shell in which your

Hello Angelines,
Do you know how the Open MPI 4.0.3 package was configured and built? That
information would be useful to help diagnose the problem.
Thanks,

Hello Slurm experts,
We have a workflow where we have a script which invoke salloc —noshell and then
launches a series of MPI
jobs using srun with the jobid= option to make use of the reservation we got
from the salloc invocation.
We are needing to do things this way because the script itself ne
Hi Christopher,
We hit some problems at LANL trying to use this SLURm feature.
At the time, I think SchedMD said there would need to be fixes
to the SLURM PMI2 library to get this to work.
What version of SLURM are you using?
