I need an example of a not-too-complicated yet intensive parallel computation in Mathematica. The result of the computation should be known before hand.
I need this to test the capabilities of a cluster. Where can I find examples of intensive parallel computation with known results?
Ideally, the intensiveness of the computation should be modifiable, so that I can run fast examples and long examples.
Downvoters alert: I'm not sure if this is on-topic here. If I see a few comments by different people saying that it isn't, I'll delete it. But please, my fragile reputation would appreciate it if you don't massively downvote this question.
Additional info: The cluster is a single system image cluster with on the order of tens of processors (say 20). By intensive computation I mean something that uses about 30GB's of RAM, and lasts about 1 day of computation. To test hard-drive capabitilities, the test should also I/O with some data of perhaps a couple of GB's that's stored on the drive. That test would satisfy me. It is important that the results be verifiable for correctness, perhaps by knowing the right answer before-hand for comparison.
