[HPC] Maintenance on the HPC Cluster, November 16, 2026

Due to maintenance on the cooling system on November 16, 2026, the HPC cluster will be throttled by approximately 50% as a precautionary measure.

Severity:
Medium
On November 16, 2026, Department 5 will perform maintenance work on the cooling system. The overall impact on the HPC cluster is expected to be minimal. Nevertheless, as a precautionary measure, the number of available nodes will be reduced by approximately 50% from 7:00 a.m. until the maintenance work is complete.
 
Cluster functionality will remain fully intact, but wait times for jobs may increase slightly. This will not affect jobs that are already running.
 
In particular, users who wish to use specific nodes should check their availability. All queues and partitions will remain available.
