IBM reclaims supercomputer lead. IBM's Blue Gene/L , to be delivered this spring to the U.S. Department of Energy's Lawrence Livermore National Laboratory, Calif., took the top spot, with a performance of 70.72 teraflops (trillion floating-point operations per second). Silicon Graphics' Columbia, built for NASA and named after the space shuttle lost in 2003, came in second, at 51.87 teraflops. The two machines displaced Japan's famed Earth Simulator to third place after that 35.86-teraflop computer had reigned supreme for two and a half years.
