Status Report on the HPC

Here is a few updates on the HPC, including the state of accounts, job preemption, and other items.

Slurm Scheduler Issues Resolved

UPDATE 7pm: The HPC issues are resolved. Thanks for your patience.


We are currently experiencing issues on the HPC where Slurm commands are not responding. Our Systems Team is working to restore the service, and we will keep you posted as soon as we resolve the issue.

OpenMPI: Major Memory Leak Bug

UPDATE: Fri, Jul 24 - 9:00pm - We have completed compiling and redeploying the new version of OpenMPI. All systems are now running OpenMPI v1.8.7.


We have just been notified of a major memory leak with OpenMPI v1.8.6 (the current version on the HPC). This is a likely reason that many nodes have been crashing and disrupting jobs on the HPC this week.

HPC Upgrade Complete

The HPC is back online, and the new Slurm scheduler is generally available to all users.

If you experience any issues submitting your jobs, or if you have questions about using Slurm, please let us know: support@rcc.fsu.edu.

You may also want to refer to our online materials listed in our prior announcement.

In addition, we are upgrading the High Performance Computing cluster to RedHat Version 7.1, which includes a new Linux kernel and many other enhancements

Here are the packages, in alphabetical order:
