Developed by China's National University of Defense Technology, Tianhe-2 held its No. 1 ranking for the second year with a performance of 33.86 petaflop/s, or quadrillions of calculations per second, on the Linpack benchmark. Linpack ranks systems by the ability to solve a set of linear equations, A x = b, using a dense random matrix A and floating point arithmetic.
The 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. China's Tianhe-1A was the top system in November 2010.
- Titan, a Cray XK7 system installed at the Department of Energy's (DOE) Oak Ridge National Laboratory. It achieved 17.59 Pflop/s and 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. It was first delivered in 2011 and achieved 17.17 Plop/s on the Linpack benchmark, according to the TOP500 release.
- Fujitsu's K computer installed at the RIKEN Advanced Institute for Computational Science in Kobe, Japan, with 10.51 Pflop/s.
- Mira, a BlueGene/Q system installed at DOE's Argonne National Laboratory, with 8.59 Plop/s on the Linpack benchmark.
- Piz Daint, a Cray XC30 system installed at the Swiss National Supercomputing Centre in Lugano, Switzerland, is the most powerful system in Europe. Piz Daint achieved 6.27 Pflop/s and is the most energy efficient system in the TOP10, consuming a total of 2.33 MW and delivering 2.7 Gflops/W.
