Further PBS Pro environment extension in CERIT-SC

CERIT-SC continues with the transfer of conventional computing machines into the new PBS Pro environment (@wagap-pro). In future, we plan to replace whole current old Torque scheduling system with new PBS Pro.

Machines currently available in a PBS Pro environment are labeled by "Pro" in the PBSMon application https://metavo.metacentrum.cz/pbsmon2/nodes/physical

Frontend zuphux.cerit-sc.cz is set (until at least half of the resources is converted) by default to Torque (@wagap) environment. To activate PBSPro @wagap-pro environment, type the following command after loging on the frontend:

    zuphux$ module add pbspro-client  ... set PBSPro environment

and back 

    zuphux$ module rm pbspro-client   ... return Torque environment

Queues available:

Note: Main difference of the PBS Pro:

New select syntax:

qsub -q uv -l select=1:ncpus=48:mem=20gb:scratch_local=20gb -l walltime=1:00:00 skript.sh

Always specify
- walltime in [hh:mm:ss] format
- size and type of the scratch <scratch_local|scratch_ssd|scratch_shared>
