Redefining the term vaporware, research scientists at Los Alamos and Lawrence Livermore Labs detonated two computer simulations. ASCI White, the world’s fastest supercomputer, ran the simulations of nuclear explosions. Scientists can now study nuclear weapon replacement components without violating the nuclear test ban, in effect since 1992. Each simulation used more than 6.6 million CPU hours, which would take home machines 1000 years to complete. The data for each experiment was equivalent to 35 times the information available in the Library of Congress.
