FAS Research Computing - Notishistorik

The MGHPCC Holyoke data center will be performing power work on May 21st -23rd. This work will take out one half (or one 'side') of the power capacity for certain rows/racks including our compute rows. Because of our power draw, one side is not enough power to keep each full rack running.

As such, we will be adding a reservation to idle half the nodes in the partitions listed below. A reservation will cause nodes to drain as jobs complete and stop scheduling new jobs on those nodes if they cannot be completed before the outage. This will allow us to idle and power down those nodes prior to the work and avoid potential blackout/brownout on those racks.

This will mean that these partitions will be up and available, but that half the nodes from each will be down (assuming an even number of nodes).

This work is part of an on-going power capacity upgrade at MGHPCC. We expect this will be the last power work needed and the facility will then provide enough additional power for future expansion as well adding overhead for the current load.

Starfish will be under maintenance Friday March 21, 2025 5pm-7pm

Starfish will be inaccessible during this period.

OOD will be updated to include a Metrics page, reachable from the Help menu

• Audience: Affects all production Open OnDemand nodes on FASSE and Cannon

• Impact: There will be minimal impact to users. Some users may encounter an error on the dashboard. Simply refresh the page a few times and the error should go away.

Logins and jobs on OOD should not be affected during this maintenance.
