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

https://doku.lrz.de/display/PUBLIC/HPC+Report

Messages for Cloud and other HPC Systems

We have observed and addressed an issue with the LRZ AI Systems that concerned some running user jobs. As of now, newly started jobs should not be affected anymore. 
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.
