Unfortunately, the Hummingbird maintenance window will be extended for another few days due to the complexity of the maintenance and the intervening holiday weekend. We made great progress, but there is still work to do. So far, we have performed the following major improvements:

• External backup of all core operating system files (not user files)
• Hummingbird has been upgraded to Alma Linux 9
• Infiniband and BeeGFS drivers have been updated
• Newest version OpenHPC has been installed and configured (HPC management software)
• Most base packages for the login node have been installed

Remaining work:

• Network changes pending verification
• Node provisioning images are still under construction
• Software modules reconstruction pending
• Partition rebalancing / queue reconfigurations (we may possibly defer to a later time)
• Verify cluster operations (after the above is completed)

While we expect the work to go smoothly, we cannot at this time give a definitive time and date for the restoration to full functionality. We will be posting regular updates to this email list as well as to the Hummingbird Slack channel and website (as appropriate).

Please feel free to contact us at hummingbird@ucsc.edu should you have any questions or concerns. We look forward to a new and improved Hummingbird soon!
