=== Overview ===
All nodes will be upgraded to Ubuntu 24.04. We have the software images ready and are currently testing them. The most important testing however comes from our users: please try out if your jobs and your modules still work as expected on Ubuntu 24.04.

New Slurm partitions have been created for Ubuntu 24.04:
* <code>main_24</code> for CPU workloads
* <code>gpu_24</code> for GPU workloads

To use these partitions, add <code>--partition=main_24</code> for CPU jobs and <code>--partition=gpu_24</code> for GPU jobs in your Slurm job submissions. Please test your workflows and report any issues by filing a support ticket with "Ubuntu 24" in the title.

==== Software Environment ====
Anunna uses [[Modules|EasyBuild]] to manage software modules. Most software should work as expected, but some applications may break due to differences between Ubuntu 20.04 and 24.04. This could be due to:
* Changes in system libraries
* Updates in compilers and dependencies
* Removal of outdated packages

We recommend you to test your workflows on the new partitions and verify that all required software modules load and function correctly. If you encounter issues:
