Seeing errors with custom Slurm configuration - AWS ParallelCluster

Seeing errors with custom Slurm configuration

Starting in AWS ParallelCluster version 3.6.0, you can no longer target single prolog or epilog scripts by including them in a custom Slurm configuration. In AWS ParallelCluster version 3.6.0 and later versions, you must locate custom prolog and epilog scripts in the respective Prolog and Epilog folders. These folders are configured by default to point to:

  • Prolog points to /opt/slurm/etc/scripts/prolog.d/.

  • Epilog points to /opt/slurm/etc/scripts/epilog.d/.

We recommend that you keep the 90_plcuster_health_check_manager prolog script and the 90_pcluster_noop epilog script in place.

Slurm runs the scripts in reverse alphabetical order. Both the Prolog and Epilog folder must contain at least one file. For more information, see Slurmprolog and epilog and Slurm configuration customization.
