New Top 500 Supercomputer List - Jaguar Chases Roadrunner, but Can’t Grab Top Spot on Latest List of World’s TOP500 Supercomputers
The 32nd edition of the closely watched list of the world’s TOP500 supercomputers has just been issued, with the 1.105 petaflop/s IBM supercomputer at Los Alamos National Laboratory holding on to the top spot it first achieved in June 2008.
The Los Alamos system, nicknamed Roadrunner, was slightly enhanced since June and narrowly fended off a challenge by the Cray XT5 supercomputer at Oak Ridge National Laboratory called Jaguar. The system, only the second to break the petaflop/s barrier, posted a top performance of 1.059 petaflop/s in running the Linpack benchmark application. One petaflop/s represents one quadrillion floating point operations per second.
