PlayStation 3 helps Folding@home with further disease research

Aside from powering some of this holiday season’s most impressive games and providing playback of high-definition movies, the Cell Broadband Engine is also exceptionally adept at medical and scientific applications requiring massive amounts of floating-point computational power.
Since joining Stanford University’s Folding@home program in March, the PlayStation 3 has led all processors in sheer productivity numbers. It should come as no surprise that Sony announced this week that PlayStation 3 consoles all over the world have helped the Folding@home project to reach a petaflop, a milestone never before reached on a distributed computing network.
"The recent inclusion of PS3 as part of the Folding@home program has afforded our research group with computing power that goes far beyond what we initially hoped," said Vijay Pande, Associate Professor of Chemistry at Stanford University and Folding@home project lead. "Thanks to PS3, we are now essentially able to fast-forward several aspects of our research by a decade, which will greatly help us make more discoveries and advancements in our studies of several different diseases."
"When we introduced PS3, we knew its incredible processing power would allow for a great deal of innovation and creativity," said Jack Tretton, president and CEO of SCEA. "It's extremely rewarding to see that the scientific community has found a way to harness PS3 technology for humanitarian purposes and we continue to be amazed at what gamers and the Folding@home community have been able to accomplish in such a short amount of time."
The Folding@home program runs simulations in protein folding, helping scientists understand – and hopefully curing – diseases such as Alzheimer's, Parkinson's and certain forms of cancer. That’s not all the PS3’s CPU is able to do for the medical community, though, as the Cell Broadband Engine is also helping doctors at Mayo Clinic with medical imaging.

RE: This is a great use of technology

I didn't downvote you but i argue that a PS3 can do any kind of calculation that an X86 machine can.

There are no types of calculations that a Turing machine can't do, it's just a matter of how much time you need to accomplish that.

And i stand 200% behind that.

That said, GPUs weren't a complete Turing machine until recently. Today you can accomplish on the GPU anything you can on your x86 CPU. These projects are called GPGPU.

Some freaks made an software audio effect processor, and audio acceleration using the GPU...

it's just a matter of how much time you need to accomplish that.
And with that disclaimer, you've given part of the reason why the PS3 is less versatile for FAH calculations than a standard CPU. GPU's are even less versatile than the PS3.
A Pentium mmx rig is a Turing machine, but that doesn't mean it is FAH-capable.
The CPU client can perform all types of FAH calculations, while the PS3 is more limited, and the mighty GPU client is very much architecturally restricted in the types of FAH calculations it can perform... subtle arguments aside.

Discussions at FAH go into greater detail as to why the GPU and PS3 clients are limited in scope, despite their awesome power.
