CoE HPC News, July 17 2023: Future heat waves, new queue and queue limits
by Yelle, Robert Brian 17 Jul '23

17 Jul '23

HPCC users, Here is the latest news regarding the COE HPC cluster: Datacenter cooling issues Over the weekend parts of the cluster had to be shut down due to cooling issues arising from the previous heat wave. The cluster is now operating at full capacity, but be advised that in the future when there is a heat advisory, the cluster will operate at reduced capacity during the weekends, and during the weekdays when necessary. DGX partition limits DGX limits have been lowered again back to 4 GPUs due to high demand. The solution I had in place that was designed to provide greater flexibility did not work out as planned, so I am working on a different solution to this which may involve significant changes to the DGX queues and policies. If anyone has any feedback or suggestions on what they would like to see, feel free to email me. Share partition limits The CPU limit on the share partition is currently capped at 32 CPUs per node. New GPU partition “ampere” A new GPU queue called “ampere” consisting of A40 GPUs has been created and is currently open to all COE users. This queue is in a trial phase for the summer. At present you can reserve up to 2 GPUs and 16 CPUs total which is subject to change based on availability and demand. Give it a shot and if you have any feedback, let me know. More changes… More changes affecting the cluster are on the way this summer, so stay tuned!

CoE HPC News, July 6 2023: Submit-a relocation
by Yelle, Robert Brian 06 Jul '23

06 Jul '23

Cluster users, The cluster is online and near full capacity, including all submit nodes and HPC portal access. Submit-a relocation This morning, submit-b and submit-c were brought down to be relocated. Early next Thursday morning the 13th, I plan to relocate submit-a. This will require that I power off submit-a, which will terminate any srun sessions running on it. For the next week, I will be draining submit-a, which means ssh access will be restricted to existing sessions, so please use submit-b or submit-c for new login and srun sessions. Jobs submitted through sbatch on this node or through the HPC portal will not be affected.
