Ada Cluster Retirement, June 30

Posted at 4/21/2021 10:11am

The Grace cluster will be replacing the Ada cluster as our primary research computing cluster. The Ada cluster will be retired in phases according to the following schedule:

  • On May 17, we will shutdown some of the compute racks in preparation to give them to the designated research groups approved by the VPR.
  • On June 1, we will shutdown the remaining compute racks. The login and data transfer nodes will remain available for retrieving and migrating data.
  • On June 30, the Ada cluster will be completely shutdown. Retrieval and/or migration of data MUST be completed by this date.

Users MUST only migrate data from Ada that will be used for future work on Grace. Any other data not intended for use on Grace that you want to retain MUST be copied to non-HPRC storage. All large quota increase requests over 10TB MUST be submitted by PIs, and will be reviewed and approved by the HPRC director.
