[slurm-users] srun and mpirun

[Mahmood Naderan]

Hi,
I see some old posts on the web about performance comparison of srun
vs. mpirun. Is that still an issue? Both the following scripts works
for test programs and surely the performance concerns is not visible
here.

#!/bin/bash
#SBATCH --job-name=hello_mpi
#SBATCH --output=hellompi.log
#SBATCH --ntasks=120
#SBATCH --time=10:00
mpirun mpihello

and

#!/bin/bash
#SBATCH --job-name=hello_mpi
#SBATCH --output=hellompi.log
#SBATCH --ntasks=120
#SBATCH --time=10:00
srun mpihello


Regards,
Mahmood
