Cheyenne upgrades scheduled for Tuesday, February 21

February 17, 2017
Major upgrades to the Cheyenne system are scheduled for Tuesday, February 21, and will require an all-day system outage starting at 9 a.m. The most significant upgrades will be to the PBS Pro job scheduler and to the program for detecting out-of-memory (OOM) events on batch nodes.

Cheyenne users should be aware that jobs submitted after 8 p.m. Monday will be held until after the system is rebooted Tuesday night. Because of the significant updates to PBS Pro, there is no guarantee that those jobs will survive the system reboot and may need to be resubmitted.
