High Priority Security Updates on Helium and Neon

Due to a high priority security vulnerability (https://access.redhat.com/articles/1332213) the HPC team is in the process of patching compute nodes. This patching will not affect any running jobs but jobs may sit in queue wait longer than normal while nodes are patched and rebooted.

Login nodes will be patched (requires reboot) during the following times:

  • Helium Cluster - Tuesday, February 3rd, 2015 at 10:00AM
  • Neon Cluster - Wednesday, February 4th, 2015 at 10:00AM

We expect each login node will be down for approximately 20 minutes. All active sessions on login nodes will be killed during these updates. Currently running jobs will not be affected by this patching.

If you have concerns about the timing of these updates please contact hpc-sysadmins@iowa.uiowa.edu
