System downtimes scheduled for Tuesday, July 10

July 6, 2018

The Cheyenne, Geyser, and Caldera clusters and the GLADE file system will be unavailable on Tuesday, July 10, starting at approximately 7 a.m. MDT to allow CISL staff to update key system software components. The downtime is expected to last until approximately 6 p.m. but every effort will be made to return the system to service as soon as possible. The updates include installing the latest version of the PBS scheduler, changes to /glade/p/ described in today’s Daily Bulletin, and completing GLADE’s transition to GPFS 5.

A system reservation will prevent batch jobs from executing after 7 a.m. All batch queues will be suspended and the cluster’s login nodes will be unavailable throughout the update period. All batch jobs and interactive processes that are still executing when the outage begins will be killed.

CISL will inform users through the Notifier service when all of the systems are restored.
