Hi Howard,
I tried to compile OpenMPI 4.1.5. When I looked configure script's help
page there was no --with-pmi2 parameter.

HI Aziz,
Did you include –with-pmi2 on your Open MPI configure line?

Hi Gilles,
Thank you for your response.
When I run srun --mpi=list, I get only pmi2.
When I run command with --mpi=pmi2 parameter, I got same error.
OpenMPI automatically support slurm after 4.x version.

Aziz,
When using direct run (e.g. srun), OpenMPI has to interact with SLURM.
This is typically achieved via PMI2 or PMIx
You can
srun --mpi=list
to list the available options on your system
if PMIx is available, you can
srun --mpi=pmix ...
if only PMI2 is available, you need to make sure Open MPI was
built with SLURM support (e.g. configure --with-slurm ...)
and then
srun --mpi=pmi2 ...
Cheers,
Gilles

Hi there all,
We're using Slurm 21.08 on Redhat 7.9 HPC cluster with OpenMPI
4.0.3 + gcc 8.5.0.
When we run command below for call SU2, we get an error message:
