According to Guinness, the PS3 accounts for about 60% of all teraFLOPS performed!On September 16, 2007, the Folding@Home project officially attained a performance level higher than one petaFLOPS, becoming the first computing system of any kind to do so, although it had briefly peaked above one petaFLOPS in March 2007. In comparison, the fastest supercomputer in the world (as of November 2007, IBM's Blue Gene/L supercomputer) peaks at 478.2 teraFLOPS (1000 teraFLOPS=1 petaFLOP).
So when you're not playing dinner time or when your about to call it a night go fold! On December 19th, Sony updated the Folding@Home client to version 1.3 to allow users to run music stored on their hard drives while contributing. Another feature of the 1.3 update allows users to automatically shut down their console after current work is done or after a limited period of time.
