China remains supercomputer superpower number 1

China remains supercomputer superpower number one

Fastest computer comes from Guangzhou, China

As supercomputer, the fastest computer of its time be designated. It does not matter on which construction of computer based. A typical feature of a modern supercomputer is its large number of processors that can access shared peripherals and a partially shared memory.

In the list of the fastest supercomputers in the world ranking for the fourth time in a row China's "Tianhe-2" ("Milky Way") to score number one. Built in Guangzhou plant comes on a computing power of 33.86 petaflops (quadrillion floating point operations per second). 

The fastest supercomputer in the world: "Tianhe-2"

Speed Master "Piz Daint" from Switzerland

Europe's fastest computer is in Switzerland. "Piz Daint" in Lugano on the Swiss National Supercomputing Center of the American manufacturer Cray delivers a performance of 6.27 petaflops. Overall, published twice a year list of top 500 lists 130 systems from Europe - in June there were 116.


Most systems in the United States

The United States operate more traditionally by far the most super computer, even if the number of 233 slightly decreased to 231 plants. The countries in Asia still operate 120 supercomputer (132 in June). In addition to the National University of Defense Technology (NUDT) operated "Tianhe-2" also managed the K Computer by Fujitsu in Japan at the Riken Advanced Institute for Computational Science (fourth place) among the top ten.

Only little changes

Overall, there were among the first ten places little change since the last publication of the list of "Top 500" in June. The only new addition is a Cray-plant with a capacity of 3.57 petaflops, which is, according to the editors of the list at an undisclosed location in the United States in the service of the government.

IBM with four systems under Top Ten

IBM had dominated the list of the top 500 for a long time with its systems. In the current issue of American IT specialist and system builders brought four more of its assets in the top ten under. According to a report by "ZDnet" it is currently constructing together with the graphics card manufacturer Nvidia and the semiconductor and network specialist Mellanox on two new supercomputers, which will go into operation in 2017. 

IBM Blue Gene

Next Generation

On behalf of the US Department of Energy are the two systems "Sierra" and "Summit" will be built with a budget of 325 million dollars, it said. For commissioning them to come to a peak power of 100 ("Sierra") and 150 to 300 petaflops ("Summit"). Accordingly, "Sierra" is to be used at the Lawrence Livermore National Laboratory, especially for simulations of nuclear weapons. "Summit" should at Oak Ridge National Laboratory in Tennessee and are used for civil and scientific purposes. 

The TOP500 list was created as a project for the June 1993 meeting in Mannheim, and then updated for the Supercomputing 93 conference held that November. The list goes back to the initiative of the Mannheim computer scientist Hans Meuer, who died in January 2014.
