heh, we did that a year ago, and we made (well, fixed the slurm one) a
qsub wrapper to avoid having to document this and retraining our users.

Hi Jürgen,
we set in our modules the variables $MPIEXEC and $FLAGS_MPI_BATCH and
documented these.
This way, by changing the workloadmanagement system or the MPI or

For my two-cents I would recommend using srun. While mpirun "works" I've
seen strange behavior especially if you are using task affinity and core
binding. Even weirder with hybrid codes that use threads and MPI.
Using srun resolves these issues as it integrates more tightly with the

over `mpirun ./my_mpi_program´? For me, both seem to do exactly the

no, the issue is whether your mpirun is slurm-aware or not.
you can get exactly the same behavior, if you link with slurm hooks.
the main thing is that slurm communicates the resources for
Hello Slurm user,

launch 1000s of jobs.
I also ran 'scontrol reconfig' and even r
