The Chinese supercomputer ‘Tianhe-2′ got recognition as the world’s fastest computer based on a survey results announced on Monday. It works double the speed of the U.S. Energy Department’s Titan machine which now ranks second.
This super computer developed by the National University of Defense Technology has once again proved the dominance of China in the field of science and technology. China is trying hard to join the global technology elite group that consists of United States, Europe and Japan.
Tianhe-2 machine has the ability to provide sustained computing of 33.86 petaflops per second. This is equivalent to 33,860 trillion calculations per second. Titan machine has a speed of just 17.59 petaflops per second. Most of the Tianhe-2′s parts are developed in China, except for its main processors, which are designed by US firm Intel.
Tianhe-2 means Milky Way-2 in English.It is the second time that China is winning such a title as Tianhe-2′s predecessor, Tianhe-1 has already ranked as the world’s fastest in November 2010. It was then replaced by Titan machine and now China has regained it’s lost position. This is a great achievement for China and many tech experts appreciate the effort taken by China to maintain it’s supremacy.
Tianhe-2 is composed of 16,000 nodes; each node uses two Intel Xeon Ivy Bridge processors and three Xeon Phi processors for a total of 3.12 million computing cores. The survey pointed out that five of the world’s 10 fastest computers are installed in the US, with the two in China, two in Germany and one in Japan.
“Most of the features of the system were developed in China, and they are only using Intel for the main compute part,” TOP 500 editor Jack Dongarra, who toured the Tianhe-2 facility in May, mentioned in a news release. “That is, the interconnect, operating system, front-end processors and software are mainly Chinese.”
The supercomputers on the Top 500 list, which is produced twice a year, are rated based on their performance in a benchmark test conducted by experts from Germany and the United States.
As a country, the U.S. dominates the Top 500, with 252 of the supercomputers on the list. China, with 66 systems, and Japan, with 30 systems, are second and third. In the top 25 list, the U.S. government’s nine supercomputers hold a place.These machines are used for modelling weather systems, simulating nuclear explosions and designing jetliners. Tianhe-2 will be unveiled at the National Supercomputer Center in Guangzho, China, by the end of this year.
