[COMPLETED] 2024-02-21: Upgrade of the queue system on Colossus

[2024-02-21 17:49 update] All affected jobs have been requeued. 85 jobs had to be cancelled, so please inspect the output of your jobs to see if they're affected.

[2024-02-21 15:45 update] Several jobs that were running at the start of the upgrade did not successfully resume. We're trying to resolve the issue. New jobs are not affected.

[2024-02-21 10:35: update] The upgrade is now done, and seems to have gone well.

[2024-02-21 10:00: update] The upgrade has now started

The queue system on Colossus will be upgraded on Wednesday (February 21) at 10:00.  During the upgrade, running jobs will be suspended, and slurm commands (squeue, sbatch, etc) will not work.  We expect the upgrade to take no more than 20 minutes.
