Caviness

The Caviness cluster was built in late 2018 according to a rolling upgradeable design strategy. Like previous community clusters, over time additional nodes will be added. But starting in the sixth year of its life, nodes exiting their warranty period will be replaced and the infrastructure surrounding them reused.

The larger amount of reusable infrastructure is afforded by the Open Compute Project (OCP) design of the cluster. Penguin Computing's Tundra design uses centralized DC power conversion in the racks to make node sleds as small and efficient as possible. Remove the old sleds and insert the new.

Many Engineering research groups own capacity in Caviness. UD IT maintains its own Caviness documentation; on this site you will find summaries specific to:

• logging in to the cluster
• compute resources present in the cluster
• storage resources available to you, when to use them, and how, including:
  • your personal home directory
  • workgroup storage available to members of a workgroup
  • high-speed shared Lustre scratch storage
• using VALET to manage your environment
