The HPC compute and data storage systems hosted at the NCAR-Wyoming Supercomputing Center were powered down this morning for the facility’s scheduled maintenance downtime. As announced previously, this maintenance window will allow CISL staff and contractors to perform critical updates to the facility’s power infrastructure in preparation for the arrival of the new Derecho system later this year.
The Casper cluster, GLADE file systems, Campaign Storage, JupyterHub, HPSS, Stratus, Quasar, and Cheyenne’s login nodes are expected to return to service by Thursday, July 29. Cheyenne’s compute nodes will remain unavailable throughout the service period, which is expected to last through Monday, August 2.
Users will be kept apprised daily on the status of the maintenance through the Daily Bulletin and the Notifier service.
