Original Post:

We will have rolling reboots of Pitzer cluster including login and compute nodes, starting from Feb 03, 2021. The rolling reboot is to update BIOS for urgent security updates as well as memory bug fixes. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. User will also expect a ~10 minute outage of login nodes at about 9AM Feb 05, 2021.

We apologize for any inconvenience this may cause you. Please contact if you have any questions.
