Switching to the new OpenPBS and Debian12

Dear users,

At the beginning of March we first announced the launch of the migration to the new PBSPro -> OpenPBS.

All available computing capacity will be available under a single PBS server pbs-m1.metacentrum.cz. We are continuing with moving the CERIT-SC (cerit-pbs) and ELIXIR CZ (elixir-pbs) clusters under the new PBS server.
The existing PBSPro servers will be decommissioned when the remaining jobs are finished. Please move your jobs already to the new environment, it will make the migration easier and faster for us to complete the move.
At the same time as the migration to the new PBS we are upgrading the OS: Debian11 -> Debian12.

Please use the new OpenPBS environment pbs-m1.metacentrum.cz for your tasks. If you don't want to change anything in your scripts, submit jobs from frontends with Debian12 OS, the queue names will remain the same, only the PBS server (QUEUE_NAME@pbs-m1.metacentrum.cz) will change.

The list of available frontends including the current OS can be found at https://docs.metacentrum.cz/computing/frontends/

About 3/4 of the clusters are now available in the new OpenPBS environment, we are working hard to reinstall the others. We are waiting for the jobs to run out.
Overview of machines with Debian12 feature: https://metavo.metacentrum.cz/pbsmon2/props?property=os%3Ddebian12
You can test whether your job will run in the new OpenPBS environment in the qsub builder: https://metavo.metacentrum.cz/pbsmon2/qsub_pbspro

For up-to-date information on the migration, see the documentation at https://docs.metacentrum.cz/tutorials/debian-12/ (we will update the migration procedure here).
