December 2025
The Fall 2025 maintenance window coincides with the campus data center generator test and is scheduled for the week of December 15th. HPC@UCD will be bringing servers down on Monday, December 15th, and they will be made available for use after planned maintenance tasks are completed. During this time, Farm, Franklin, and Hive will be unavailable for use, and all jobs will be stopped.
All Clusters¶
During the maintenance window, the following software items will be updated:
- CVMFS (Software Module Distribution)
- Linux Cgroups
- NVidia GPU drivers
- Open OnDemand
- Slurm
- ZFS
Farm Specific¶
Farm sells hardware and storage with a five-year guarantee. Many Farm hardware components have exceeded their lifecycle and will be retired during the December 2025 maintenance window. At the request of CAES IT, all hardware more than five years old will be retired, and those Slurm partitions will be removed. Additionally, the partition names for the newer hardware will be renamed.
