Revisions to Slurm Configuration v2.1.0 on Caviness

This document summarizes alterations to the Slurm job scheduler configuration on the Caviness cluster.

A new rack (r04) has been added to the Caviness cluster. Nodes in the new rack must be integrated into the Slurm configuration for job scheduling.

• The Slurm nodes.conf file will be modified to include r04.
• The Slurm partitions.conf file will be modified to:
  • Adjust node assignments for existing workgroups who purchased node(s) in r04
  • Add new workgroups who purchased node(s) in r04
• The Slurm topology.conf file will be modified to include OPA switches/HFIs in r04
  • The /opt/shared/slurm/add-ons/bin/opa2slurm utility (written by IT-RCI staff) will be used to automatically map the OPA network

No downtime is expected to be required.
