Scheduled Maintenance on Milgram

As a reminder, scheduled maintenance will be performed on Milgram beginning Monday, June 3, 2019, at 8:00 am. Maintenance is expected to be completed by the end of day, Wednesday, June 5, 2019. During this time, logins will be disabled, and Milgram’s storage will not be available. We ask that you logoff the system prior to the start of the maintenance, after saving your work and closing any interactive applications.An email notification will be sent when the maintenance has been completed, and the cluster is available.

As the maintenance window approaches, the Slurm scheduler will not start any job if the job’s requested wallclock time extends past the start of the maintenance period (8:00 am on June 3, 2019). If you run squeue, such jobs will show as pending jobs with the reason “ReqNodeNotAvail”. (If your job can actually be completed in less time than you requested, you may be able to avoid this by making sure that you request the appropriate time limit using “-t” or “–time”.) Held jobs will automatically return to active status after the maintenance period, at which time they will run in normal priority order.

If you have questions, comments, or concerns, please contact us at hpc@yale.edu.

Sincerely,

Paul Gluhosky
