On July 16th, from 9am to 5pm, we will be running maintenance on our systems. We will briefly shut down the login nodes, and it may be necessary to shut down the /hpc/* file systems at short notice - we apologize in advance for any disruption caused.
You may find your HPC jobs are not running because they are waiting on the reservations that are in place for Wednesday. You can still get jobs to run by submitting them with the wallclock time set to something that terminates before 9am Wednesday.
