Remote X11/HTTP

You may find yourself wanting to run a GUI or visualization application on one of the clusters and direct the output to the computer in front of you. Some applications, like VisIt, are designed specifically to support this. However, you can often accomplish this with applications that weren't in one of two ways:

  • forwarding the X Window System protocol, X11, or
  • tunneling the HyperText Transfer Protocol, HTTP.

Which method you need to use depends on which protocol your application implements.
