====== Revisions to Slurm Configuration v2.1.0 on Caviness ======

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

===== Issues =====

==== Caviness Expansion 2.1 ====

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.

===== Implementation =====

  * 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

===== Impact =====

No downtime is expected to be required.
