Debian 12 & new PBS server

Recently we set up a new frontend zenith running on Debian 12 - see Complete list of frontends, their homes and OSs.

At the same time, we are preparing to transfer from PBS Pro to Open PBS.

A new Open PBS server pbs-m1.metacentrum.cz is up and running.

Old PBS Pro servers meta-pbs.metacentrum.cz, cerit-pbs.cerit-sc.cz and elixir-pbs.elixir-czech.cz have been decommissioned and their workload was transferred to pbs-m1.metacentrum.cz.

Elixir users

New queue

Users of the elixir group shall submit their jobs to reserved queue elixircz@pbs-m1.metacentrum.cz, e.g.

qsub -l walltime=1:0:0 -q elixircz@pbs-m1.metacentrum.cz -l select=1:ncpus=1:mem=400mb:scratch_local=400mb

elixir users still have their reserved pool of nodes with separate planning.

Known issues

Python on Debian 12

typing “python” on zenith frontend will get you 3.x.x version of Python
if you need some 2.x.x version of Python, you have to add it through a module (module avail python/)

Missing libraries

Try module add debian11/compat if you run into “library XY: no such file or directory” type of problem.
