Power outage - Panne électrique


Some Graham nodes will be shut down starting 05/02/2022 6:50 AM until noon (approximately 5 hours) to permit electrical work.

During this time, these nodes will be unavailable to run jobs, so you may notice a decrease in cluster throughput.  A reservation is in place which will prevent new jobs from starting on affected nodes, but it's possible some long-running jobs may be killed.

We do not expect this to affect login or DTN nodes, jobs running on unaffected nodes, or storage.
