[Tetralith-users] Tetralith available

[Mats Kronberg]

Dear Tetralith users,

You can now login to Tetralith again.

The downtime became slightly longer than announced due to some
unexpected problems we ran into.

Rocky Linux 9 is now the default operating system in Tetralith. What
this means: if you login to tetralith.nsc.liu.se you now end up on a
login node running Rocky Linux 9 ("EL9"), and jobs you submit from there
will start on compute nodes running EL9.

If you have not already done so, we strongly encourage you to start
testing your jobs on and then running them on the EL9 compute nodes.

Compute nodes with the old operating system CentOS 7 will only be
available until January 8th 08:00 CET. You can use these by logging into
tetralith-el7.nsc.liu.se and submitting jobs from there.

If this is confusing or news to you, please read
