Sony teamed up with US biologists to make folding@home compatible with the PS3 console.
The project harnesses the capacity of thousands of PCs to examine how the shape of proteins, critical to most biological functions, affect disease.
FAH say a network of PS3's will allow performance similar to supercomputers.
With 10,000 machines joined together the researchers calculate they should be able to do a thousand trillion calculations per second.
If that was achieved it would be nearly four times as fast as the world's most powerful supercomputer, IBM's BlueGene/L System, capable of 280.6 trillion calculations per second.
