HPC group schedules regular maintenances every 3 months to update system software and to perform other tasks that require a downtime.

The date of the next maintenance is listed in the message of the day displayed at login (when ssh-ing to the cluster).

Note: Queued jobs will not start if they cannot complete before the maintenance begins. In the output of the squeue command the reason for those jobs will state (ReqNodeNotAvail, Reserved for maintenance) . The jobs will start after the scheduled outage completes.
