'World's Fastest Supercomputer' Crowned in US The Titan
supercomputer at Oak Ridge National Laboratory was crowned the
fastest in the world just a few weeks after its debut. In the
clash of the world's supercomputing titans, a new U.S.
supercomputer named "Titan" is king. The $100-million Titan
seized the No. 1 supercomputer ranking on the Top500 List with a
performance record of 17.59 petaflops per second (quadrillions
of calculations per second). The supercomputer, a Cray XK7
system based at Tennessee's Oak Ridge National Laboratory,
leaped past the former champion, the Sequoia supercomputer at
California's Lawrence Livermore National Laboratory. The top
five supercomputers in the world are: - Titan Cray XK47 at Oak
Ridge National Laboratory (17.59 petaflops/s) - Sequoia
BlueGene/Q at Lawrence Livermore National Laboratory (16.33
petaflops/s) - Fujitsu's K computer at the RIKEN Advanced
Institute for Computational Science in Kobe, Japan (10.51
petaflops/s) - The Mira BlueGene/Q computer at Argonne National
