Running programs remotely through ssh is great with Linux or Mac OS X with the –X flag. Not quite as easy with Windows. I lean on PUTTY for my ssh, which of course does not come with an X Server. Xming will piggy back with Putty to run an X Server on windows and allow you to remote the application with the –X flag. The application has worked great for running GUIs off the HPC through ssh.
