Reminder: Cheyenne compute nodes down May 6-11 during NWSC electrical repairs

May 10, 2019

NCAR HPC system users are reminded of the scheduled downtime for Cheyenne’s compute nodes Monday, May 6, through Saturday, May 11, while extensive electrical repairs take place at the NCAR-Wyoming Supercomputing Center. Cheyenne’s login nodes, the Casper cluster, and GLADE will remain available on UPS power. HPSS is scheduled to be down briefly for electrical recabling on Monday, May 6, from 7 a.m. to 1 p.m. MDT but otherwise is expected to be available during the week.

A major Cheyenne operating system update also is being planned and will require an extended downtime, most likely in late June or early July. Details will be announced in the Daily Bulletin when the dates are set.
