Dear Loris, thank you for your clarification. You are right. It seems that I have phrased my question somewhat misleadingly. For our next cluster we will switch from Moab/Torque to Slurm and have to adapt the documentation and example batch scripts for the users. Therefore, I wonder if and why we should recommend (or maybe even urge) our users to use srun instead of mpirun/mpiexec in their batch scripts for MPI jobs. > I suspect the question, which I also have, is more like: > > "What difference does it make whether I use 'srun' or 'mpirun' within > a batch file started with 'sbatch'." That's exactly the question I wanted to ask. Thanks again.
