Cheyenne batch jobs offline due to network fabric issues

July 5, 2019

The Cheyenne system’s batch nodes were taken offline at 8 a.m. today to allow CISL system administrators to address some network fabric issues that have affected batch job performance this week. The work required a pause of the PBS job scheduler and Cheyenne queues.

Jobs that were still running as of 8 a.m. were killed. Others that were queued but not running before 10:30 p.m. on Thursday do not need to be resubmitted.

CISL will attempt to return the batch nodes to service by midday today. In the meantime, login nodes and the Casper cluster will remain operational. Watch for updates during the day through the Notifier service. Thank you for your patience.
