A "Gravity Grid" made of an eight-PS3 cluster used in parallel processing mode. Why? To solve an enormously complex astrophysics problem -"what happens when a super-massive black hole, about a million times the mass of our own sun, swallows up a star.""Overall, a single PS3 performs better than the highest-end desktops available and compares to as many as 25 nodes of an IBM Blue Gene supercomputer."
