Cheaha compute nodes located at the Technology Innovation Center on campus will be undergoing maintenance from June 16-22, resulting in reduced CPU and GPU capacity during those days, as well as reduced memory limits for jobs. Please plan Research Computing needs around the maintenance window.
Cloud.rc (OpenStack) and Cheaha nodes within DC Blox will be undergoing maintenance during the week of April 21, 2025. Cloud.rc and Cheaha "amperenodes,” "pascalnodes,” and "intel-dcb" partitions will be inaccessible during maintenance. Note this means all GPU nodes will be inaccessible. Planned growth requires us to move hardware within the DC BLOX data center. Please plan your Research Computing needs around this maintenance window. If you need additional assistance, please reply to this email or reach out to support@listserv.uab.edu.
Note
This window applies only to researchers using GPFS5.
We will be performing upgrades on the GPFS5 storage system to optimize stability. During this process, researchers on the GPFS5 side will be unable to login via SSH, and Open OnDemand (https://rc.uab.edu) will appear unresponsive.
The maintenance window is scheduled for the morning of Tuesday, September 16, 2025, from 6:00 AM through 6:00 PM. We expect the process to take no more than 12 hours. We will restore service as soon as work is complete.
