Some applications may require a Graphical User Interface (GUI), or are interactive programs which are resource-intensive (such as CPU or RAM).

These may include applications such as:

• matlab
• fluent/ansys
• dl_poly
• gams
• gaussian
• spm
• stata
• octave
• plink
• R/perl/python/ruby scripts which are resource-heavy

Where to Run

Rather than running these applications on the headnode, where they may use excessive resources, you must run them on a compute node.

How to Run

You must request an interactive allocation through the queuing system.

Interactive resources which use GUI interfaces can be executed from a Linux or Mac OSX or Windows desktop. It is done using X-forwarding over an SSH tunnel.

The following pages detail the procedures for these operating systems:
