CCR staff strive to maintain up-to-date and secure resources for the UB community.  In order to do this we plan monthly maintenance periods for the UB-HPC and faculty clusters.  These clusters are offline on the last Tuesday of every month for maintenance, unless otherwise noted.  Downtime starts at 7am and is usually completed by 5pm.  Jobs are held in the UB-HPC queue unless otherwise noted by CCR beforehand.  The faculty cluster allows jobs to run right up until the downtime.  Any running jobs are killed when the downtime starts.  If you're a faculty cluster user that does not want your job to be killed, please make sure to only request a wall time that allows your job to complete prior to 7am on downtime days.


Other services experience maintenance downtimes several times a year.
