HPCC users,
Here is the latest news on the CoE HPC cluster:
Springbreak maintenance:
The HPC Cluster will undergo its regularly scheduled quarterly maintenance after Finals Week, during Springbreak (March 22-26). The following maintenance activities will be performed:
OS updates
BIOS and firmware updates
Infiniband updates
Slurm update and configuration changes
Power redistribution for various compute nodes
Miscellaneous hardware maintenance as needed
Maintenance activities will begin the Monday after Finals week, and the entire cluster will be offline starting Tuesday the 23th at 8am, and will remain offline until Wednesday the 24th at 4pm. After that, maintenance will continue on parts of the cluster throughout the week. Jobs found running on the Univa cluster by Tuesday morning will need to be terminated, and Slurm jobs scheduled to run into that offline period will remain pending with the message “ReqNodeNotAvail, Reserved for maintenance”. If you wish for your Slurm job to start and finish) before the maintenance period begins, you will need to adjust your time limit accordingly, e.g. to change to 2 days do:
scontrol update job {jobid} TimeLimit=2-00:00:00
Alternatively, you can cancel your pending job, adjust your walltime (using the —-time option) and resubmit.
If you have any questions or concerns, let me know.

HPC Manager
