Tokyo, November 1, 2007 – Sony Computer Entertainment Inc. (SCEI) today announced that PLAYSTATION®3 (PS3®) computer entertainment systems, part of Stanford University’s Folding@home™ program, have enabled the distributed computing project to be recognized by Guinness World Records™ as the most powerful distributed computing network in the world. The record was initially set on September 16, 2007 as Folding@home surpassed one petaflop(*1), a computing milestone that has never been reached before by a distributed computing network. In addition to this, the collective efforts of our users have enabled PS3 alone to reach the petaflops mark on September 23, 2007.

The record is a testament to the widespread participation of PS3 users from around the world—currently more than 670,000 unique PS3 users have registered to the Folding@home network, bringing the overall computing power of the program to more than a petaflop. Thanks to PS3’s powerful Cell Broadband Engine™ (Cell/B.E.), scientists will now be able to make greater progress in their studies of protein folding and its link to diseases such as Alzheimer’s, Parkinson’s and certain forms of cancer.
