First 3D Simulations of Complete Nuclear Detonations

jhiv writes: "The National Nuclear Security Administration (NNSA) reports that 'Los Alamos and Lawrence Livermore national laboratories have completed the first full-system three-dimensional simulations of a nuclear weapon's explosion'. The simulations are two of the largest computer simulations ever attempted, each taking weeks to complete on the ASCI White supercomputer. The Los Alamos team used the ASCI Blue Mountain supercomputer to visualize the results. Additional coverage can be found in this story in the Albuquerque Journal."

ASCII doesn't work! (all the time)

Looks like the ASCII computers have a significant amount of downtime - Was a reliability analysis ever done? Checkpointing the nuclear simulations takes 50% runtime. ASCII is an $800 million white elephant nuclear dud simulator. Uncle George W. may have to unsign Uncle Billy's Test Ban Treaty, but then again Afganistan is a better test site than Yucca Flats....
