PBS maintenance outage tomorrow

April 20, 2018

Cheyenne system administrators will perform preventative maintenance procedures on the PBS job scheduler tomorrow, Tuesday, April 24, beginning at noon MDT. The maintenance is expected to take approximately one hour to complete.

Most PBS commands will not work during the maintenance outage, including qstat and qsub, and new job submissions will not be possible.

No batch jobs are expected to be lost as a result of the maintenance. 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.

Users will be notified when PBS is returned to service.
