BlueGene/L to simulate nuke explosions

Leading nuclear scientists with top security clearances will gather next summer at a screening room east of San Francisco and witness the results of the greatest effort ever in supercomputing.

Using a computer doing 360 trillion calculations a second, scientists at Lawrence Livermore National Lab will simulate the explosion of an aging nuclear bomb in three dimensions. The short, highly detailed video produced by the world's fastest computer will attempt to illustrate how missiles dating back to the Nixon administration would perform today.
