Top 500 list – November 2013

top-500-supercomputersWorld’s No. 1 supercomputer is still Tianhe-2, developed by China’s National University of Defense Technology, with a performance of 33.86 petaflop/s on the Linpack benchmark

Titan, a Cray XK7 system installed at the Department of Energy’s (DOE) Oak Ridge National Laboratory, remains the No. 2 system. It achieved 17.59 Pflop/s on the Linpack benchmark. Titan is one of the most energy efficient systems on the list consuming a total of 8.21 MW and delivering 2.143 gigaflops/W.

Sequoia, an IBM BlueGene/Q system installed at DOE’s Lawrence Livermore National Laboratory, is again the No. 3 system. It was first delivered in 2011 and achieved 17.17 Pflop/s on the Linpack benchmark.

Fujitsu’s K computer installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan, is the No. 4 system with 10.51 Pflop/s on the Linpack benchmark.

Mira, a BlueGene/Q system installed at DOE’s Argonne National Laboratory, is No. 5 with 8.59 petaflops/s on the Linpack benchmark.

The new entry in the TOP10 is at No. 6 –Piz Daint, a Cray XC30 system installed at the Swiss National Supercomputing Centre (CSCS) in Lugano, Switzerland and now the most powerful system in Europe. Piz Daint achieved 6.27 Pflop/s on the Linpack benchmark. Piz Daint is also the most energy efficient system in the TOP10 consuming a total of 2.33 MW and delivering 2.7 Gflops/W.

Rounding out the TOP10 are Stampede at the Texas Advanced Computing Center of the University of Texas, Austin, which slipped to No. 7; a BlueGene/Q system called JUQEEN installed at the Forschungszentrum Juelich in Germany is No. 8; No. 9 is taken by Vulcan, another IBM BlueGene/Q system at Lawrence Livermore National Laboratory; and No. 10 is the third system in Europe, the SuperMUC, installed at Leibniz Rechenzentrum in Germany.

The total combined performance of all 500 systems on the list is 250 Pflop/s. Half of the total performance is achieved by the top 17 systems on the list, with the other half of total performance spread among the remaining 483 systems.
