I think they found all the prime numbers already :)))

To impress friends check out (parallel rendering):


I believe seti at home and folding at home can use clusters (google for them)

Then there is also parallel genetic algorithms. some coding needed
but an interesting use for extra cycles.


There are others, google around. If you want to learn about
MPI, check out this tutorial (or grab one of the MPI books):
Or, for more general information, check out
