New cluster
 

So I've just finished installing a new cluster here at work, and was told that I should just test it out and mess around with it some.

But I really have no idea what would be a test of it's computer power (16nodes @ at total of 50Ghz processing power).


Note that I don't have graphical support on these machines, and they're running the Rocks 3.2.0 distro (Basically Redhat linux).


So my question is, if you had a cluster, what would you do with it?

Calculate some VERY large prime numbers. There are programs to do it, but I don't remember the URL for it.
Also SETI@Home would work too.
