New Version of ANSYS 2025.R1 availableToday the new version of the ANSYS software, Vers. 2025.R1 has been installed, tested and made available on CoolMUC-4 and SuperMUC-NG under operating system SLES 15. The new version has been made the new default version for all major ANSYS software components. |

Maintenance SuperMUC-NG Phase 2We have started a planned maintenance period for the phase 2 system. The maintenance of SuperMUC-NG Phase 2 will continue for the whole week. |
| Messages for Linux Clusters |
Maintenance: Change in Slurm configuration on CoolMUC-4Please take note of the following announcement! Although CoolMUC-4 has more powerful CPUs, the system has much less CPU cores and nodes than the predecessor system. The resources are limited. The demand is increasing. We are therefore forced to make changes to the Slurm configuration. This will mainly have an impact on the job processing on the cluster segments "serial" and "cm4". Please refer to Job Processing on the Linux-Cluster for details on the updated cluster configuration. A maintenance was carried out on Friday 21 to apply the changes. The most important changes are:
Users need to do after maintenance:
We strongly recommend that users of the "serial" cluster check whether their workflows can be parallelized, in order to be able to benefit from the parallel cluster segment "cm4". If even "cm4" is insufficient, you may also consider an application for a (test) project on the SuperMUC-NG. Do you need further consulting? Don't hesitate to contact us via Servicedesk or via virtual Zoom meeting in our HPC Lounge. |
Access to the new CoolMUC-4 has been openedIn December 2024 the access to the new CoolMUC-4 (CM4) Linux Cluster has been granted. The CM4 cluster comprises some ~12.000 cores based on Intel® Xeon®Platinum 8480+ (Sapphire Rapids) interconnected by an Infiniband network. Please have a look at the updated documentation before filing a ticket to the LRZ Service Desk. Please mind the changed outline of the module system and the number of 112 CPU cores and 512Gb RAM per compute node on CM4 hardware. |
Remarks on Spack software stack availability and INTEL related modulesPlease note: Since the last maintenance at the end of November 2024 the latest LRZ software stack spack/23.1.0 is set as default on the CoolMUC-4 partitions! The old software stack spack/22.2.1 is still available via the according module. |

The AI Systems (including the MCML system segment) will undergo a maintenance procedure between February 17th and 19th, 2025. On these days, the system will not be available to users. Normal user operation is expected to resume during the course of Wednesday, February 19th. We are currently observing and investigating connection issues to https://login.ai.lrz.de. UPDATE: The issue has been resolved. The AI Systems will be affected by an infrastructure power cut scheduled in November 2024. The following system partitions will become unavailable for 3 days during the specified time frame. We apologise for the inconvenience associated with that. Calendar Week 46, 2024-11-11 - 2024-11-13
The AI Systems (including the MCML system segment) are under maintenance between September 30th and October 2nd, 2024. On these days, the system will not be available to users. Normal user operation is expected to resume during the course of Wednesday, October 2nd. The previously announced scheduled downtime between 2024-09-16 and 2024-09-27 (Calendar Week 38 & 39) has been postponed until further notice. |
The system will remain in user operation up to the scheduled maintenance at the end of September.
