Aurora will undergo maintenance on Monday, October 13, 2025, starting at 13:00 UTC (8:00 CDT 10/13) and ending at 00:00 UTC on Tuesday, October 14 (19:00 CDT 10/13). During maintenance, the compute image with Intel's User (UMD) and Kernel Mode Drivers (KMD) (Agama 1146.12 / rolling release 2523.12), and oneAPI 2025.2.0, which is currently available in next-eval queue, will be rolled out to the majority of nodes across Aurora.

We will have at least 2048, and up to 2413 nodes, with the current production image in a new queue called 'legacy’,  which will be available to all teams that are unable to run against the new image. Some teams will have higher priority to run in the legacy queue. aurora-uan-000[7-8] will have the current production user environment, although users will not be able log in directly to these UANs and will need to ssh to them after logging in to aurora.alcf.anl.gov.
