Today, at the opening session of the 2013 International Supercomputing Conference in Leipzig, Germany, the latest update (the 41st version) to the Top 500 list of supercomputers was announced, and a new Chinese system, the Tianhe-2, has taken first place honors. The system achieved performance of 33.86 petaflops per second (3.386 × 1016 floating point operations per second) on the LINPACK benchmark; the Tianhe-2 (in English, Milky Way-2) will be deployed at the National Supercomputer Center in Guangzho, China, by the end of the year. The system has 16,000 nodes, each with multiple Intel processors, for a total of 3,120,000 processor cores.
The Titan system at Oak Ridge National Laboratory, ranked number 1 in the November, 2012 list, and the Sequoia system, at the Lawrence Livermore National Laboratory, previously ranked number 2, have both moved down one place, to number 2 and number 3, respectively. The two system are still noteworthy as being among the most energy-efficient in use. Titan delivers 2,143 Megaflops/Watt, and Sequoia 2,031.6 Megaflops/Watt.
The total capacity of the list has continued to grow quickly.
The last system on the newest list was listed at position 322 in the previous TOP500 just six months ago. The total combined performance of all 500 systems has grown to 223 petaflop/sec, compared to 162 petaflop/sec six months ago and 123 petaflop/sec one year ago.
