    The community MySQL server is still being migrated to a new server. We also continue to troubleshoot issues with the older VM farm, which still runs a few VMs, which should be available but may be less responsive. We will update on the progress again tomorrow. Thank you for your understanding.

    We have released HPC clusters and jobs should now start running. All services should now be functional, apart from the MySQL database server and associated websites. Work on this will continue with expected release sometime tomorrow (December 18). Thank you for your patience.

    If you notice issues with anything other than MySQL and websites, please let us know at helpdesk@chpc.utah.edu.

    As of approximately 10:45 p.m. on December 16, storage systems, the CHPC website, and standalone servers (such as biochemistry cryo-EM servers) are functional. Network issues on the morning on December 17, however, have affected access to CHPC resources. CHPC staff are working to resolve issues.

    Remaining services, including virtual machines (VMs) and HPC clusters, are still under maintenance. We anticipate having systems functional today (December 17).

    A downtime on December 16 and 17 will affect all CHPC resources, including clusters (redwood, granite, notchpeak, kingspeak, and lonepeak), standalone servers, virtual machines (VMs), and storage. This downtime is necessary to replace core network infrastructure. Reservations on the computing clusters have been put in place to ensure jobs will complete prior this downtime. Systems will be brought up on December 17 as the network replacement and any related system administration work is completed. An announcement will be made as resources are made available.
