World’s Fastest Supercomputers Titan and then Sequoia
From
The 40th edition of the twice-yearly TOP500 List of the world’s top supercomputers was released today (Nov. 12, 2012). The Oak Ridge National Laboratory Titan, a Cray XK7 system, achieved 17.59 Petaflop/s (quadrillions of calculations per second) on the Linpack benchmark. Titan has 560,640 processors, including 261,632 NVIDIA K20x accelerator cores.
In claiming the top spot, Titan knocked Lawrence Livermore National Laboratory’s Sequoia out of No. 1 and into second place. Sequoia, an IBM BlueGene/Q system, was No. 1 in June 2012 with an impressive 16.32 Petaflop/s on the Linpack benchmark. With 1,572,864 cores, Sequoia is the first system with one million or more cores.
Rounding out the top five systems are Fujitsu’s K computer installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan (No. 3); a BlueGene/Q system named Mira at Argonne National Laboratory (No. 4); and a BlueGene/Q system named JUQUEEN at the Forschungszentrum Juelich in Germany (No. 5), which was upgraded and is now the most powerful system in Europe.
