This is freaking amazing. I was checking out some message boards last night at the Folding Forums at Stanford, a group that tracks the Folding at Home application. You know, that's the software that runs on Sony PS3 or PS2 gaming consoles, all linking up over the Internet and using their spare cycles to help the university process vast amounts of Alzheimers research data? To my astonishment, I discovered that a small legion of 13,000 PS3s running the Folding at Home app account for most of the computing power in the project, amounting to about 56 percent (PS3s = 316 measured TFLOPS) of the total.

On average, between the superfast and superslow PCs, 159,033 PCs are only doing about half that much. (151 TFLOPS). Essentially, 13,000 PS3s have just made the Folding at Home Project the fastest distributed computing project on the planet, ever. (I believe it used to be SETI @ Home, which was something like 280 TFLOPS.) This also means the PS3 met Stanford professor Vijay Pande's expected one-month goal in one day. (We'll update this post with confirmation once Dr. Pande gets back to us.)

The project just needs about 18,000 more PS3s participating to make the Folding at Home project the first distributed computing project to hit a Petaflop. To put that into perspective, the Japanese MDGRAPE-3, RIKEN's supercomputer, has about a Petaflop of computing power.

And the potential goes on from there. There are 2 million PS3s in the wild, and over 100 million PS2s shipped thus far. PS3 owners, what are you waiting for? Get the word out to other PS3 owners. Let's help cure Alzheimer's disease.

DISCUSSION

Windows:

159113 active / 151 TFLOPS = approx 0.95 GFLOPS per client

Mac OS X (All):

11417 active / 14 TFLOPS = approx 1.23 GFLOPS per client

Mac OS X (Intel Only):

2704 active / 7 TFLOPS = approx 2.59 GFLOPS per client

Analysis

It would seem that, all-in-all, Mac OS X machines contribute approximately 30% more computing power per active client. I certainly wouldn't have guessed that.

Also impresive: Intel-based Mac OS X machines blow away the Windows average, offering 164% more computing power.

Conclusion:

More Mac users need to be running F@H, especially if they've got an Intel box.
