Update: Effects of maintenance scheduled for July 13-18 at NWSC

June 11, 2020

Users are reminded that the Cheyenne HPC system will be unavailable for one week in mid-July to allow CISL staff and external contractors to perform power infrastructure repairs at the NCAR-Wyoming Supercomputing Center (NWSC). Some other systems will be unavailable for one day.

The maintenance period will begin Monday, July 13, and Cheyenne is expected to be returned to service by Saturday, July 18. The Casper cluster, GLADE and Campaign Storage file systems, data-access nodes, and HPSS will remain available throughout the week except for Tuesday, July 14. Some maintenance on those systems has been scheduled since our previous announcement. Watch for more details and updates in the Daily Bulletin.
