We are approaching our annual maintenance period, which coincides with the MGHPCC’s data center maintenance shutdown. Unity, including login access and storage, will be offline from Monday, May 20th at 9 am Eastern through Friday, May 24th for necessary maintenance and upgrades. We appreciate your patience during this disruption and will work to restore Unity access as quickly as possible following network restoration Friday afternoon.
We encourage users to plan accordingly. Keep in mind that your job will not start if the time limit overlaps the start of maintenance. You can use the -t
flag with Slurm to set a time limit that shortens your job to fit into the acceptable window. For example, to restrict your job to 2 days and 12 hours, you can add -t 2-12:00:00
. In addition, you can add --deadline=2024-05-20
to your job so it will remove itself from the queue if it won’t run in time for the maintenance. We will be purging the queues during maintenance, so anything queued will not run after the reservation is lifted. You will receive a follow up email once Unity is back online and ready for use again.
We invite you to join us on our Unity User Community Slack where you can get the most up-to-date information and chat with the Unity team. Sign up with your University credentials to join. If you’re unable to join automatically with your University email, please send a ticket to hpc@umass.edu for a direct invite.
