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
