Compute Farm Reduced Capacity: 23-Aug-2021 to 25-Aug-2021
Starting Monday, 23-Aug-2021 @ 8:00 AM, most CLASSE Compute Farm batch queues will be disabled in advance of a Wilson Lab East Module power outage on Wednesday, 25-Aug-2021. Please note that interactive and CHESS queues are excluded from this two-day pre-outage pause; jobs running in these queues will instead be terminated early morning on Wednesday, 25-Aug-2021, when the East Module power is cut. Power is expected to be restored by midday.
Any terminated jobs can be resubmitted immediately to the "all.q" and "interactive.q" queues for continued processing throughout the power outage. This continuity of service is made possible by two new farm nodes that have been deployed in Wilson 221. However, farm capacity will be severely degraded, so you may need to wait for resources to become available before your job is scheduled.
