[UPDATE] shared-scheduler Degraded Performance

Dear Researchers,

In addition to the previously announced maintenance day activities, we will be migrating the Torque component of shared-sched to a dedicated server to address the recent performance issues. This move should improve the scheduler’s response time to client queries such as qstat, and decrease job submission and start times when compute resources are available. While you do not need to do anything to prepare for this migration, we advise that you make note of any jobs queued at the start of maintenance just in case. As always, please direct any questions or concerns to We thank you for your patience.

Dear Researchers,

At this time the scheduler is functional, although some commands may be slow to respond. We will continue investigating to ascertain the source of these problems, and will update accordingly. Thank you.


We are aware of a significant slowdown in the performance of the shared-scheduler since last week. Initial attempts to resolve the issue towards the end of the week appeared successful, but the problems have restarted and we are continuing our investigation along with scheduler support. We appreciate your patience as we work to restore full functionality to shared-scheduler.
