Running Graphical Applications

We do not recommend running graphical applications. They have to be run interactively, and a human must be around to logout when the job is finished. However, we realize some users need to run graphical applications.

UNIX systems use the X Window System for graphical applications. In order to forward graphics to your local screen, you’ll need an X Window client installed. Linux distributions should already have one. Mac OS X users should download and install XQuartz.

Please follow the guide below to run your graphical application:
ssh -X hpcwoods (Or otherwise connect to hpcwoods with X Forwarding enabled)
ssh -X maple
qsub -IX -lncpus=1 -lmem=5gb

Note that the resources requested in the last command should be tailored to your application and the data you’re running through your application. The more resources you request, the more careful you should be about stopping the interactive job when not actively using it.

You can easily test X forwarding with the xeyes or xclock command.
