There are MinNodes and MaxNodes settings that can be defined for each partition listed in slurm.conf [1]. Set both to 1 and you should end up with the non-MPI partitions you want.

Sometimes CPU>1 jobs are scheduled to run on more than one node (which would be fine for MPI jobs of course...) Is it possible to automatically set "--nodes=1" for all jobs outside of the "mpi" partition (that we setup for message passing jobs)? Thank you, Manuel -- Dr. Manuel Holtgrewe, Dipl.-Inform.
