The new ANSYS Release 2025.R2 has been installed, tested and rolled-out on SuperMUC-NG Phase 1 and CoolMUC-4. ANSYS 2025.R2 has been made the new default ANSYS Release on those systems and the LRZ documentation has been updated in due course. |
The new Siemens PLM Release of StarCCM+ 2025.3.1 (= 2510.0001 = v20.06.010) has been installed, tested and rolled-out on SuperMUC-NG Phase 1 and CoolMUC-4. StarCCM+ 2025.3.1 has been made the new default StarCCM+ Release on those systems and the LRZ documentation has been updated in due course. Older versions of StarCCM+ with version numbers 2024.x.1 and 2025.x.1, x=1,2,(3) remain concurrently available on the LRZ HPC systems until the first 2026.1.1 release in the next year (April 2026). |

All (LRZ and MCML) DGX systems had to be powered off. This message will be updated as as new information becomes available. The AI Systems (including the BayernKI and MCML system segments) will undergo a maintenance procedure between September 8th and 10th, 2025. On these days, the system will not be available to users. Normal user operation is expected to resume during the course of Wednesday, September 10th. The LRZ AI Systems have to undergo a short maintenance early next week. For this, the system will be drained over the weekend and start-up of new jobs will be delayed until after the maintenance. We expect the actual downtime to not exceed more than 10 minutes. The AI Systems (including the BayernKI and MCML system segments) will undergo a maintenance procedure between May 19th and 21st, 2025. On these days, the system will not be available to users. Normal user operation is expected to resume during the course of Wednesday, May 21st. |
