We will upgrade of the SuperMUC-NG Phase 1 (CPU) operating system to SLES15-SP7.
- Starting Saturday 14.03.2026 8:00 we will block the queues of Phase 1 and Phase 2 so all running jobs can finish regularly. SLURM will be upgraded. All queued jobs will be deleted and jobs need to be resubmitted after the maintenance.
- All login nodes will be shutdown with the start of the maintenace on Monday morning. The file systems WORK and SCRATCH will not be accessible during the maintenance. Please gather your data beforehand.
- After the maintenance a new software stack 24.5.0 already available on Phase 2 and the LRZ CoolMUC-4 cluster will become default. The old stack 22.2.1 will be still available, but cannot be supported any longer in case of problems. We will provide an overview of the major changes and guidelines for the transition.
Please follow this message for updates and progress of the maintenance.
