Messages for all HPC System

A new software stack (spack/23.1.0) is available on the CoolMUC- 2 and SuperMUC-NG. Release Notes of Spack/23.1.0 Software Stack

This software stack provides new versions of compilers, MPI libraries, and most other applications. Also there are significant changes w.r.t module suffixes (specifically MPI and MKL modules) and module interactions (we have added prerequisites of MPI and compilers for high-level packages to adhere to the compatibility in loaded modules in your terminal environment). Please refer to the release notes for detailed changes. 

This software stack is rolled out as a non-default on both machines. You will have to explicitly swap/switch spack modules to access the new software stack. The best way is to purge all loaded modules and load the Spack/23.1.0 like,

$> module purge ; module load spack/23.1.0

Please be aware, 

  • Using the "module purge" command will unload all previously loaded modules from your terminal shell, including automatically loaded ones such as "intel," "intel-mpi," and "intel-mkl." This step is crucial to prevent potential errors that may arise due to lingering modules.

  • In the future, when version 23.1.0 or later versions of the Spack software stack become the default, we will no longer automatically load any modules (e.g., compilers, MPI, and MKL). This change will provide users with a clean environment to begin their work.

We request you to reach out to us for any suggestions and questions. Use the "Spack Software Stack" keyword when you open a ticket at https://servicedesk.lrz.de/en/ql/create/26 .

Week - : Maintenance on Phase 1 and 2. Login nodes, WORK and SCRATCH filesystems will be unavailable. Job processing is interupted

ANSYS version 2024.R2 has been installed on the SuperMUC-NG Phase 1 running under SLES15. The software will not be provided on SuperMUC-NG Phase 2 (Intel Pontevecchio GPU system), since the ANSYS software is so far only supporting NVidia and AMD GPUs.

Messages for Linux Clusters

Please be aware that the CoolMUC-2 system has reached End-of-Life and can only be operated on a best-effort basis.

Week starting : Maintenance of Linux Cluster CANCELLED!

ANSYS version 2024.R2 has been installed on the LRZ Linux Clusters running under SLES15, i.e. the software is available on CoolMUC-2 and CoolMUC-4.
Due to the outdated OS on CoolMUC-3 (SLES12) the software cannot be provided on this older Linux Cluster system anymore.
The software documentation will be updated in due course.

Messages for Compute Cloud and other HPC Systems

The previously announced scheduled downtime between 2024-09-16 and 2024-09-27 (Calendar Week 38 & 39) has been postponed until further notice. (warning) The system will remain in user operation up to the scheduled maintenance at the end of September (see below).

The AI Systems are increasingly showing interruptions of operation. We are aware of the situation, but a full recovery may take some time. UPDATE: The issues have been addressed.

 The AI Systems (including the MCML system segment) will undergo a maintenance procedure 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 AI Systems will be affected by an infrastructure power cut scheduled later this year. Based on current information, the following system partitions will become unavailable during the specified time frames (scope and dates may be subject to change; this notice will be updated as needed).
