Messages for all HPC System

The new version of the CFD solver software StarCCM+ by Siemens PLM (Vers. 2502.0001 = 20.02.008 = 2025.1.1) has been installed, tested and rolled out on CoolMUC-4 and SuperMUC-NG Phase 1.
The documentation has been updated in due course: https://doku.lrz.de/siemens-plm-on-hpc-systems-10746502.html

Messages for Linux Clusters

Intro of the CoolMUC-4 Linux Cluster

In December 2024 the Linux Cluster CoolMUC-4 (CM4) has been introduced. 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 modules

Please 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.
Important Note 1: The naming conventions for INTEL related modules (Compiler, MPI, MKL) in both Spack software stacks differ from each other, so that users eventually need to update their SLURM scripts accordingly.
Important Note 2: On CM4 the Intel related modules are no longer preloaded as default modules. Users are self-responsible for loading required Intel compiler, Intel MPI and Intel MKL modules in their corresponding SLURM scripts. Various versions and flavours of these modules are provided through the Spack software stacks.

Messages for Compute Cloud and other HPC Systems

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.
