Many may be aware of the Folding@home project run by Stanford University, but thanks to Sony now they have a Guinness record. This record certifies the Folding@home project as the most powerful distributed computing system, reaching over 1 petaflop (thousand trillion floating point operations per second). In comparison the SETI@home project has only reached 256 teraflops (265 million floating point operations).
What does Sony have to do with the record. Well more than 600,000 PS3 owners have been donating their spare cpu cycles to the project and this along with others donating their PCs spare cycles have netted the project the World Record.
