|Messages for SuperMUC-NG|
Please read https://www.lrz.de/aktuell/ali00938.html for details on a scheduled maintenance starting May 16.
On Monday, April 4, 2022, a new version of the spack-based development and application software stack will be rolled out.
The new spack version will be loaded as default starting April 11, 2022
After that date, you will be still able to switch to the previous spack stack with
> module switch spack spack/21.1.1
We strongly recommend recompiling self-built applications after the roll-out. See also https://doku.lrz.de/display/PUBLIC/Spack+Modules+Release+22.2.1 for details.
Base core frequency of jobs has been set to 2.3GHz. Higher frequencies possible using EAR.
The new hpcreport tool is now available to check job performance and accounting on SuperMUC-NG. Please check out
|Messages for Linux Clusters|
The new version 2022.1.1 of the StarCCM+ CFD solver by Siemens PLM Software has been installed and rolled out on all Linux Clusters (cm2, mpp3, housing systems), the "old" and the "new" RVS systems as well as on SuperMUC-NG. The module system and the documentation have correspondingly been updated.
Due to the observed issues with compute node overcommitment in all 2020.* versions of StarCCM+ with the new updated SLURM scheduler (see here: https://www.lrz.de/aktuell/ali00936.html) the StarCCM+ versions prior to 2021.1.1 have been decommissioned and removed from the module system. The 2022.1.1 version is the new default version of StarCCM+.
There are 4 "new" Remote Visualization (RVS_2021) nodes available. The machines are in production mode. Nodes are operated under Ubuntu OS and NoMachine. Usage is limited to 2 hours and if you need a longer period of time, please file an LRZ Service Request. For more details please refer to the documentation.
Messages for Cloud and other HPC Systems
The work on the LRZ AI Systems to address the recently observed stability issues has been concluded. All users are invited to continue their work. We closely monitor system operation and will provide additional updates if needed. Thank you for your patience and understanding.
We have identified the likely root cause for the ongoing issues with the LRZ AI and MCML Systems following the latest maintenance downtime. We continue work towards a timely resolution and can currently not guarantee uninterrupted & stable system availability. For further details, please see LRZ AI Systems
The LRZ AI and MCML Systems did undergo a maintenance procedure from April 25th to April 27th (both inclusive.) During this period, the system was not available to users. Normal user operation did resume on 2022-04-27 16:30.
