Cheyenne compute nodes down due to power outage

July 23, 2019

A power outage this morning at the NCAR-Wyoming Supercomputing Center (NWSC) brought down the Cheyenne system's compute nodes. Cheyenne batch jobs that were running when the outage occurred were lost. Power has been restored to NWSC but its ongoing stability is uncertain at this time.

The Cheyenne login nodes, Casper cluster, GLADE file system, and HPSS remain up and available to users. Watch for updates during the day through the Notifier service.
