Livermore Labs Blowing Up Atomic Bombs
"Using a computer doing 360 trillion calculations a second, scientists at Lawrence Livermore National Lab will simulate the explosion of an ageing nuclear bomb in three dimensions. <>In a room about half the size of a football field, BlueGene/L is a series of interconnected six-foot (1.8 meters)- high racks holding 16 modules, each packed with massive computing power. The first part of BlueGene, built by IBM, became operational in mid-December at 90 trillion calculations a second; the rest should be ready by April. Even at its ultimate 360 trillion calculations a second speed, the simulation will take two to four months, lab officials say. This same calculation would have taken 60,000 years if done on technology available a decade ago."
