Brief PBS maintenance outage scheduled Tuesday, February 5

January 30, 2019

CISL system administrators will update the PBS workload management server at noon MST on Tuesday, February 5. The update is expected to take less than 60 minutes to complete. The new version of PBS, 18.2.3, provides performance and stability improvements and a number of important bug fixes.

Most PBS commands, including qstat, will not work during the update, and new Cheyenne job submissions will not be possible. Jobs that are executing when the maintenance begins will continue to run without interruption. Jobs that are queued for execution or in a hold state will remain in those states until PBS is returned to service. Access to Cheyenne’s login nodes will not be interrupted.
