Cheyenne compute nodes returned to service

May 10, 2019

The Cheyenne system’s compute nodes were rebooted, tested, and returned to service shortly after midnight today, a day earlier than planned. Worsening weather conditions in Cheyenne, Wyoming, resulted in some delays to this week’s electrical repair efforts at the NCAR-Wyoming Supercomputing Center (NWSC). However, most of the scheduled repairs and maintenance were completed as planned.

Some unfinished work that affected Cheyenne’s availability was suspended and will be rescheduled to be completed at a later date. CISL thanks everyone for their patience and cooperation during the extensive repair efforts at the NWSC facility this week.
