Abstract :
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.
