最新top500出炉,Cray Titan登顶

Advanced reports that Oak Ridge National Laboratory was fielding the world’s fastest supercomputer were proven correct when the 40th edition of the twice-yearly TOP500 List of the world’s top supercomputers was released today (Nov. 12, 2012). Titan, a Cray XK7 system installed at Oak Ridge, 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.

The other new system in the Top 10 is Stampede, a Dell PowerEdge C8220 system installed at the Texas Advanced Computing Center at the University of Texas in Austin. It uses the brand new Intel Xeon Phi processors (previously known as MIC) to achieve its 2.6 Petaflop/s.

In all there are 23 systems with Petaflop/s performance on the latest list, just four-and-a-half years after the debut of Roadrunner, the world’s first Petaflop/s supercomputer.
