Cell-based "Roadrunner" Tops Elusive Petaflop Mark

prunedude writes "The NY times is reporting that an American military supercomputer, assembled from components originally designed for video game machines, is more than twice as fast as the previous fastest supercomputer, the I.B.M. BlueGene/L. To put the performance of the machine in perspective, Thomas P. D'Agostino, the administrator of the National Nuclear Security Administration, said that if all six billion people on earth used hand calculators and performed calculations 24 hours a day and seven days a week, it would take them 46 years to do what the Roadrunner can in one day."

    probably because most of those people would either try to eat the calculator or sell it for food and medicine

    "There are numerous other scientific and social areas in which the military advances society, with far more practical results than do-gooders in other government or public institutions."

    It's because the military doesn't have the scrutiny and oversight other institutions do, lets face it. Do public institutions besides the miilitary get secret prison's and liscense to do whatever the want? The military is not held back by moral qualms. We've seen this with all sorts of classified documents coming out of the government. The military has budgets that are kept secret. For anyone to claim the 'military helps us' vs public institutions, we'd have to do an analysis. But that would be fairly difficult and politically sensitive, now wouldn't it?
