Also, be sure to audit your epilog and prolog scripts to make sure they won't cause harm when running in parallel with another SLURM instance. Be careful if you are using SLURM cgroups support, as cgroups created for each parallel instance of SLURM will exist in the same namespace, and that may cause unexpected issues. mark > >> >> Thanks, >> >> >> >> Howard Gieselman >> >>
