Status and Service Updates

Savio HPC Services are back online except for OOD: Wed, 7/10

The Savio HPC system (with the new Rocky Linux 8 OS installed and implemented), with the exception of the Open OnDemand (OOD) service, has been returned to service and is available to users. We will need more time to configure OOD, so please do not attempt to use OOD at this time. Please note, however, that the Savio documentation has not yet been fully updated to reflect changes due to the new Rocky Linux 8 OS (e.g., changes in the software stack and software module farms, changes in how to compile user code, etc.). Therefore, until the updates in the Savio documentation have been completed, we suggest that Savio users refer to the LBNL Science IT documentation for the Lawrencium HPC system at https://scienceit-docs.lbl.gov/hpc/rocky8-migration/ , https://scienceit-docs.lbl.gov/hpc/software/software-module-farm/ , and https://scienceit-docs.lbl.gov/hpc/software/module-management/ (which is similar to though not exactly the same as Savio) as a temporary guide to some of the changes that have taken place on the Savio system due to the Savio Rocky Linux 8 OS upgrade.

Savio Downtime: Fri, 7/5 - Wed, 7/10

As you know, we have been working on upgrading the Savio operation system to Rocky 8. To complete the OS upgrade, we coordinated with the data center group on campus to combine our work with the long-awaited power work needed at the data center. The joint downtime will start at 5PM on Friday, 7/5. We anticipate to return the services by the end of Wednesday, 7/10. A scheduler reservation is in place to ensure no jobs run after 5PM on Friday, 7/5. If you plan to submit jobs, please request the appropriate wall time to ensure job completion before the downtime. Otherwise, your jobs will wait in the queue until Savio is back online.
