Re: [OMPI users] MPI_Init_thread error

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,

When we run command below for call SU2, we get an error message:
