how to set corenumber on cluster for MATLAB+MPI-fortran parallel jobs

8 views (last 30 days)
Hi,
I have a MATLAB job like this
parfor i = 1:100
system('mpirun -np N fortran_mpi.exe')
end
In case i set parfor corenum for MATLAB as M, and processor number for fortran MPI command as N, I wonder how should I set an optimial SLURM script to submit and run my MATLAB job on cluster. Is this one good? I just set the cpu-per-task as the N*M.
#SBATCH --ntasks=1
#SBATCH --threads-per-core=1
#SBATCH --cpus-per-task=N*M
thanks

I am not too familiar with SLURM but from this question and others I think it looks good.
It appears you might need N*M + 1 to account for a MATLAB client or head worker though.
