Hello, dear developers.
I'm here with another stupid question.
I'm trying to run simulation on a cluster with SLURM and get error: "number of ranks is 1 and number of domains is 14".
As you can see cluster thinks that i give him only 1 cpu and prints this message from every task.
This is how my SLURM script looks:
#!/bin/sh
#SBATCH -n 56
#SBATCH --cpus-per-task 4
#SBATCH -o %j.out
#SBATCH -e %j.err
$MPIRUN python3 c5g7-3d-unrodded.py | tee openmoc.log."SLURM_JOBID"

Could you help me writting this script correctly to run it with MPI?

An important clarification: when I run this model on a PC via mpirun, everything works, so the problem is not in the python file.
