Running jobs on our servers

• You cannot run jobs directly on the head node or computre 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 an interactive 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

• If you need to run MPI jobs, please advise the system administrator so that the necessary security access can be enabled for your login.
