We have just been notified by the manufacturer of a critical firmware update that needs to be applied to SeaWulf to ensure we can continue to provide a robust computational environment. Out of an abundance of caution, we are taking an emergency maintenance window, scheduled for ~3 hours from now at 3:30 PM today. This window is expected to last for ~24 hours.
During this maintenance window, all Seawulf login nodes and queues, as well as the storage will NOT be available.
We apologize for this unforeseen development, and thank you for your patience while we apply these critical firmware updates.
