Two-factor authentication will become mandatory on SuperMUC-NG and Linux Cluster as of September 18, 2023! Please refer to the official 2FA announcement!
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,
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 .

SuperMUC-NG: Maintenance finished. Back in operation.
: Please see https://status.lrz.de/affected/h%C3%B6chstleistungsrechner/ for a scheduled maintenance starting on September 4.
|Messages for Linux Clusters|
See https://status.lrz.de/issues/linux-cluster/2023-09-25_maintenance/ for the current maintenance on HPDA and CoolMUC4 clusters.
After a failure in the LRZ cooling infrastructure (see https://status.lrz.de/issues/linux-cluster/2023-09-13-cooling-failure/ ) all Linux cluster systems are now back in normal operation.
Messages for Compute Cloud and other HPC Systems
The LRZ AI Systems (including the MCML system segment) did undergo a maintenance procedure between July 24th and 25th, 2023. On these days, the system was not be available to users (until ~11:30, 2023-07-25).
