  • You cannot run jobs directly on the head node or servers, you should use the Torque / PBS queue environment to run your jobs.
    • If for some exceptional reason you need to run a job directly on one of the servers (e.g. a job using a Linux GUI environment, please discuss your needs with our system administrator (johann.swart at up.ac.za).
  • If you need a terminal session on one of the servers (e.g. to compile code, setup jobs, test jobs), you can do this by using the qsub interactive mode, for example:
> qsub -I q=queue_name -l nodes=1:ppn=1 -l walltime=01:00:00
