Since CentOS 7, the Linux Operating System of CLAIX, is outdated, and since CentOS Linux 8 reached End Of Life (EOL), we have to shift to a new Linux distribution.  We have selected Rocky Linux 8.7, which is also Red Hat Enterprise compatible.

Going hand in hand with this change, we also prepared the shift to a new software environment based on EasyBuild and Lmod. These tools are also widely used at other HPC centers. We expect them to improve the user experience and the maintainability from the administrator’s perspective.

However, for you as a user, both changes require that you

(1.) learn how to use the new module system (e.g., names of the modules changed, toolchains, etc.) and

(2.) recompile your software and

(3.) revise and possibly modify your batch scripts accordingly.

Understanding that you need time to prepare for these changes, we will offer support for the old (CentOS 7) and the new (Rocky Linux 8) environment in parallel for a transition period of approx. 7 weeks, ending on April 30th, 2023. During this period, more and more compute nodes will be migrated to the new environment. Consequently, the waiting times for jobs scheduled to run in the old environment might increase over time.

In this online course we will present an overview on the changes.
