Announcements

June 25, 2025

Due to recent high temperatures, a portion of the SeaWulf compute nodes has been taken offline to prevent data center overheating. Most affected jobs have been requeued, but we recommend checking your job status and resubmitting if needed. The compute nodes will be brought back online over the next few days, as weather permits.  All login nodes remain available.

Thank you for your understanding as we take these necessary precautions to protect the system.
