It's running at 'petaflop' speed. That's geek speak for a thousand trillion calculations per second.
Still not quite as fast as the Almighty, but pretty impressive.
The petaflop barrier, which has been the golden ring of supercomputing since the teraflop barrier was broken 11 years ago, is a goal that many companies, including Cray Inc., Hewlett-Packard Co., Sun Microsystems Inc. and SGI, all have been shooting for. IBM beat them to the punch but the other contenders are still at its heels. Now IBM is on to the next goal, creating an exascale system.
