June 2013

Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, is the world’s new No. 1 system with a performance of 33.86 petaflop/s on the Linpack benchmark, according to the 41stedition of the twice-yearlyTOP500 list of the world’s most powerful supercomputers. The list was announced June 17 during the opening session of the 2013 International Supercomputing Conference in Leipzig, Germany.

Tianhe-2, or Milky Way-2, will be deployed at the National Supercomputer Center in Guangzho, China, by the end of the year. The surprise appearance of Tianhe-2, two years ahead of the expected deployment, marks China’s first return to the No. 1 position since November 2010, when Tianhe-1A was the top system. Tianhe-2 has 16,000 nodes, each with two Intel Xeon IvyBridge processors and three Xeon Phi processors for a combined total of 3,120,000 computing cores. 

Titan, a Cray XK7 system installed at the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory and previously the No. 1 system, is now ranked No. 2. Titan achieved 17.59 petaflop/s on the Linpack benchmark using 261,632 of its NVIDIA K20x accelerator cores. Titan is one of the most energy efficient systems on the list, consuming a total of 8.21 MW and delivering 2,143 Mflops/W.

Sequoia, an IBM BlueGene/Q system installed at DOE’s Lawrence Livermore National Laboratory, also dropped one position and is now the No. 3 system. Sequoia was first delivered in 2011 and has achieved 17.17 petaflop/s on the Linpack benchmark using 1,572,864 cores. Sequoia is also one of the most energy efficient systems on the list, consuming a total of 7.84 MW and delivering 2,176.6 Mflops/W.

Fujitsu’s “K computer” installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan, is now the No. 4 system with a performance of 10.51 Pflop/s on the Linpack benchmark using 705,024 SPARC64 processing cores.

A second BlueGene/Q system, Mira, installed at Argonne National Laboratory is at No. 5 with 8.59 petaflop/s on the Linpack benchmark using 786,432 cores.

Rounding out the Top 10 are the upgraded Stampede at the Texas Advanced Computing Center of the University of Texas, Austin; JUQUEEN at the Forschungszentrum Juelich in Germany (and the most powerful system in Europe); an IBM BlueGene/Q system at Lawrence Livermore National Laboratory; SuperMUC, an IBM iDataplex system installed at Leibniz Rechenzentrum in Germany; and Tianhe-1A at the National Supercomputing Center in Tianjin, China.
