The new Chinese supercomputer “Tianhe-2” (“Milky Way-2”) headed by a fresh rating of the top 500 most powerful computer systems in the world.
The performance of this amounts to 33.86 petaflops supercomputer, which is almost twice the maximum performance of the former leader of the October list of Top 500 supercomputer Titan, which has now slipped to second place with 17.59 petaflops.
Previous reincarnation Chinese monster – “Tianhe-1A” – 2.57 petaflops performance made her debut in the ranking of the top 500 for the first place in November 2010.They are still in the rankings, to 10th position. As you can see, the two and a half years, the Chinese computing power has grown into more than 13 times.
The machine is designed and assembled by the Chinese National University of Defense Technology (NUDT). The authorities claim that the supercomputer will be used as “an open platform for research and education.”
Technical details of the design, see here . Briefly, the system consists of 3.12 million cores, including modules 32 thousand Intel Xeon E5-2600 v2 and 48 thousand coprocessors Xeon Phi. All combined in 16 thousand nodes, each of which is set on 88 GB of memory, that is a total of 1.4 petabytes of RAM. All running Kylin Linux.
Energy efficiency “Tianhe-2” is quite high. At its fastest supercomputer consumes 17.8 megawatts of energy. If you turn on the cooling system – 24 megawatts.
