Thanks Christopher,
No worries!
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
That's right, these messages are coming from PMIx code rather than MPI.
I too noticed that if I set PMIX_DEBUG=1 the chatter from srun stops.
Yeah, it looks like setting PMIX_DEBUG to anything (I tried "hello") stops these messages from being emitted.
Slurm RPMs with that patch will go on to Perlmutter in the Thursday maintenance.
All the best, Chris -- Chris Samuel : http://www.csamuel.org/ : Berkeley, CA, USA
