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.

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 M
