Thanks, knighthawk.
To give credit where credit is due, the random number generator was discovered by Pierre L'Ecuyer, Richard Simard, E. Jack Chen, and W. David Kelton.
Knighthawk, check out the ThreadWorker class at
http://iharder.net/macosx/threadworker . If you launch two threads, each to run the math operations, each processor on a DP system should be set to work, and since it's not very RAM intensive, you should see near 100% utilization of both processors.
BTW, do you only update the progress bar every 100,000 iterations or so?
