    Update to scope of planned maintenance on July 14: CHPC storage administrators will need to reboot storage systems in the General Environment as part of planned maintenance. As a result, home directories, the sys branch (/uufs/chpc.utah.edu/sys/), and virtual machines (VMs) in the General Environment will be briefly unavailable during the planned maintenance window. This outage is necessary to replace fans that have failed in the storage system. If you have questions about the impacts of this outage, please contact the CHPC at helpdesk@chpc.utah.edu.

    The Center for High Performance Computing will have a downtime on Tuesday, July 14, 2026. The downtime will begin at 8:00 a.m. MDT and continue through the afternoon. It will affect high-performance computing clusters (granite, notchpeak, kingspeak, lonepeak, redwood; Open OnDemand) and standalone servers (including narwhal, beehive, and CryoSPARC and ColabFold servers) in the General and Protected Environments. In addition, storage systems in the General Environment will be rebooted during the maintenance window, which will affect access to storage and virtual machines. This downtime is necessary to apply patches and updates to systems following recent operating system vulnerabilities.

    CHPC system administrators will apply updates and reboot systems in a rolling fashion throughout the day on July 14. There will be interruptions to the availability of HPC clusters and standalone servers during this time. CHPC staff will also migrate some internal services and systems, which will briefly affect the availability of metrics reported on the CHPC Portal.

    Network administrators will also update software on network devices in the Protected Environment, though network updates are not expected to cause outages or interruptions. Additionally, storage administrators will update firmware; this, too, should have no effect on availability.

    If you have any questions or concerns about the downtime or its effects, please contact the CHPC at helpdesk@chpc.utah.edu. Thanks for your support while we work to keep research computing resources secure.
