An I.B.M. machine has reclaimed the title of world's fastest supercomputer, overtaking a Japanese computer that had caused shock waves at United States government agencies when it set a computing speed record in 2002.
... The International Business Machines computer is based on a computing technology, called BlueGene/L, that takes an approach radically different from that used by the Japanese supercomputer, called the Earth Simulator....
The I.B.M. supercomputer has surpassed the Earth Simulator, built by the NEC Corporation, in running the Linpack benchmark, a test program that solves a dense system of mathematical equations. I.B.M. announced yesterday that the Blue Gene/L system had attained a sustained performance of 36.01 trillion calculations per second, or teraflops, eclipsing the top mark of 35.86 teraflops reached in 2002 by the Earth Simulator in Yokohama.
