	Since every PVM process essentially behaves as a normal UNIX process,
(almost?) anything you can do in a normal process, you can do in a PVM
process. I recently took a parallel programming course here where we had
to write a wave simulation using PVM. I chose to incorporate an X Windows
interface into the application to show each iteration of the alogrithm.
The animation works fine. The only inconvenience of programming such an
application as the one above is that all of the display data must be
present on the host that is actually generating the display, meaning
possible large amounts of network communication.
