NWSC maintenance and systems downtimes update

July 14, 2020

All work scheduled for Monday at the NCAR-Wyoming Supercomputing Center (NWSC) was completed on time and without incident. Nortek engineers and CISL’s Cheyenne Admin Support Group completed repairs on several of Cheyenne’s cooling distribution units. CISL’s Infrastructure Support Group Cheyenne and external contractors began this week’s repair efforts on the facility’s power infrastructure. CISL HPC systems engineers updated critical system software stack components and HPE completed replacements of 11 of the 16 identified faulty manifolds.

The Casper cluster, GLADE and Campaign Storage file systems, HPSS, data-access nodes, and remote access services FastX and VNC will be unavailable today from 7 a.m. until approximately 7 p.m. CISL’s pre-production implementation of JupyterHub will be available after Cheyenne is restored to service later this week.

Cheyenne is expected to be returned to service on Saturday, July 18. Watch for regular updates in CISL’s Daily Bulletin and Notifier service.
