Simple Mandelbrot fractal generation is good, too. I remember doing an 
MPI Mandelbrot fractal program as a student back in the day. It's really 
useful, because you can visually see the speed up as you add more cores.

A quick google of 'MPI Mandelbrot" showed many interesting hits on this 
topic.
