The Negishi cluster will be unavailable Wednesday, June 21, 2023 from 8:00am - 5:00pm EDT for scheduled maintenance. The cluster will return to full production by Wednesday, June 21st, 2023 at 5:00pm EDT.

During this time, Negishi will have the operating system patched and maintenance updates and tuning performed on its InfiniBand network fabric. In addition, more compute nodes will be incorporated into the cluster, bringing it to full design specification and increasing standby capacity approximately two-fold.

Any Slurm jobs which request a walltime which would take them past Wednesday, June 21st, 2023 at 8:00am EDT will not start and will remain in the queue until after the maintenance is completed.
