Preface
CentOS 7 has reached its end of life. For this reason the operating system (OS) of Lise's CPU partition will be updated to Rocky Linux 9. This affects all login and compute nodes equipped with Intel Xeon Cascade Lake processors ("clx" for short). Lise's GPU partitions ("a100" and "pvc") are not affected.
...
The OS migration phase starts with two 2 login nodes and 112 compute nodes already running Rocky Linux 9 for testing, while the other nodes remain available under CentOS 7. After an initial testing period, a major fraction of nodes will be switched to Rocky Linux 9 to allow for general job production under the new OS. In the last step, the few nodes still under CentOS 7 will be converted to Rocky Linux 9, too. During the migration phase the use of Rocky Linux 9 "clx" compute nodes will be free of charge.

What remains unchanged
node hardware and node names
communication network (Intel Omnipath)
file systems (HOME, WORK, PERM) and disk quotas
environment modules system (still based on Tcl, a.k.a. “Tmod”)
access credentials (user IDs, SSH keys) and project IDs
charge rates and CPU time accounting (early migrators' jobs are free of charge)
