Fri., 6/12/2026: Savio4_htc nodes are not back online

We would like to share an additional update following our maintenance completion notice. At this time, Savio4_htc nodes are not back online, as we are still working to resolve a network connectivity issue affecting them. Until this is resolved, the affected nodes will remain reserved. We will continue this work on Monday and will send another update as soon as Savio4_htc nodes are returned to service. Thank you for your continued patience and understanding.

Fri., 6/12/2026: June 8 Week-Long Savio Maintenance Is Complete

We’re happy to let you know that the week-long maintenance outage that began on June 8 is now complete, and services have been restored. During this maintenance window, we completed the following major updates: (1) Updated the Lustre OS for the scratch file system. (2) Upgraded Slurm from version 22.05 to 25.05. (3) Applied a kernel security patch to the Rocky 8.10 Linux operating system. (4) Upgraded Open OnDemand from version 3 to 4.0.11. Important: During the Slurm upgrade process, all pending jobs were removed from the queue. If you had pending jobs before the downtime began, please check your job list and resubmit any jobs as needed. We’re excited to bring these improvements online as part of our continued efforts to improve the reliability and stability of the Savio environment. Thank you again for your patience and support!

Planned Outage the week of June 8 for Scratch OS Upgrade

We have scheduled a planned outage affecting the Savio cluster during the week of June 8. DDN recommended this upgrade, and we are undertaking it partly in response to the recent outages many of you have experienced. While this upgrade is not a guaranteed remedy, we believe it is an important and necessary step toward enhancing the system's overall reliability and stability. We appreciate your patience and cooperation as we work to improve the Savio environment.
