To use X11 in an interactive Torque (PBS) shell, first ssh into the login node from your local machine with the -X or -Y flag:

ssh -X

To route the tunnel to your local machine from a compute node, pass the X flag to qsub as well:

qsub -IX -l nodes=1:ppn=28 -q short

This will enable X11 tunnelling to your local machine.

For users on OSX and Windows, there are X-Window managers that can be installed. Recommendations for OSX include Quartz, while Windows users can install X-ming or Moba X-term on Windows.
