    Most user-facing systems have been rebooted to address the potential security issue. There may be a small number of outstanding systems, but most users will not encounter service interruptions when such systems are updated. Thank you for your patience and understanding. If you have any questions or concerns, please contact the CHPC at helpdesk@chpc.utah.edu.

    Thank you for your patience with security-related service interruptions on Center for High Performance Computing systems today. All clusters (granite, notchpeak, kingspeak, and lonepeak in the General Environment and redwood in the Protected Environment) have been returned to service by the team at the CHPC. System administrators have also brought virtual machines (VMs) in the Protected Environment back online and are continuing work on VMs in the General Environment. We will continue to provide updates on the status of systems here.

    The Center for High Performance Computing is taking proactive, precautionary measures to mitigate a security issue that requires immediate attention. CHPC staff will reboot systems in a rolling fashion throughout the day. This will result in access and service disruptions. Running jobs and active sessions on CHPC systems, including jobs on compute nodes and sessions on interactive nodes and Open OnDemand, may be lost as systems are rebooted.

    The CHPC will provide additional information and updates throughout the day as services are brought back online. We apologize for the inconvenience and appreciate your patience and support.
