[slurm-users] MPI_Init_thread error

[Aziz Ogutlu]

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:

/$ srun -p defq --nodes=1 --ntasks-per-node=1 --time=01:00:00 --pty bash -i/
/$ module load su2/7.5.1/
/$ SU2_CFD config.cfg/

/*** An error occurred in MPI_Init_thread/
/*** on a NULL communicator/
/*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,/
/***    and potentially your MPI job)/
/[cnode003.hpc:17534] Local abort before MPI_INIT completed completed 
successfully, but am not able to aggregate error messages, and not able 
to guarantee that all other processes were killed!/
