IN YOUR FACE, EARTH SIMULATOR! USA! USA! IBM's Blue Gene/L tops the list of world's fastest supercomputers, bringing the coveted title back to our shores for the first time in three years. IBM's bad boy can make 70.72 trillion calculations per second, almost twice as many as NEC's girly man Earth Simulator. Meanwhile, my four-year old Dell desktop sadly did not make the list, probably slowed by all the Lindsey Lohan nipple slips shots clogging my Web cache.
