Over the weekend, a video game system became the heart of the most powerful supercomputer on earth. As I write this, Playstation 3 game consoles all over the world are working together to power through 493 trillion calculations per second in a group effort to find cures for Alzheimer's, Huntington's Disease, Mad Cow Disease, and several forms of cancer. To put that into perspective, IBM’s Blue Gene, considered to be the fastest unclassified supercomputer, reportedly maxes out at 367 trillion calculations per second. And the Playstation 3 cluster is still growing.
The game consoles’ owners have volunteered to run a special software package developed at Stanford by a group called Folding@home. Their task is to simulate protein folding, the process whereby the human body produces new proteins. Alzheimer’s and other diseases appear when human proteins become malformed. Exactly how normal protein production goes bad and eventually leads to these diseases is unknown, because the processes are extremely complicated, and they happen in milliseconds.
So scientists have begun simulating these complex processes via software—but it’s no light-weight task. Most protein folding requires banks of powerful computers and days, if not months, of processing time to simulate just a few seconds of biological reaction. The “distributed computing” approach to tackling big problems isn’t new. Several other projects are working to cure AIDS, study global warming, and even scan the cosmos for extraterrestrial life by dishing their software out over huge networks of computers. But Folding@home is the first to tap the power of the Playstation 3, which, it turns out, is a computational powerhouse.
Stocked with seven processors, all tuned to perform heavy number crunching, the Playstation 3 puts the average single-processor PC to shame. (All that computing power is also using quite a bit of energy, but that’s another story.)
The Playstation 3’s formidable numbers are surely being noticed by the other distributed computing projects, so pretty soon video game consoles could also be predicting the weather, simulating nuclear explosions, or unlocking the origins of the universe. To follow the progress of the Folding@home project, be sure to check in on the regular updates published on their website.
