Further nodes available in the PBSPro experimental environment

Further nodes available in the PBSPro experimental environment

Most of computing nodes and some frontends has been moved from Torqure scheduling system (@arien) to PBS Pro (@arien-pro) environment.

In future, we plan to replace whole current old Torque scheduling system with new PBS Professional, so we highly recommend you to start to use the PBSPro right now.

Please note:

• PBSPro server: arien-pro.ics.muni.cz (server is not directly accessible)
• Frontends: tarkil.grid.cesnet.cz, alfrid.meta.zcu.cz, nymha.zcu.cz (further frontends will be available soon)
  
• GPU cluster is accessible via dedicated gpu@arien-pro.ics.muni.cz and gpu_long@arien-pro.ics.muni.cz queues
• PBS Pro comes with new qsub syntax "select" which differs in major aspects from old Torque syntax -- request for job with two processors on each of 3 chunks (nodes), 1 GB of RAM, 1 GB of local scratch, 1 hour walltime, 1 licence for Matlab: 

  •   qsub -l select=3:ncpus=2:mem=1gb:scratch_local=1gb -l walltime=1:00:00 -l matlab=1 skript.sh

• Scratch requirement must be stated individually. When requesting scratch, it is necessary to specify its type. There is no default type of scratch! (scratch_local=1gb)!!!

• Qsub assembler for PBSPro and other information from PBSPro were integrated to PBSMon: https://metavo.metacentrum.cz/en/state/personal
• Documentation for new scheduling system PBS Professional can be found at wiki https://wiki.metacentrum.cz/wiki/PBS_Professional
