1、Add the “made in China” tag to yet another product: the worlds fastest supercomputer.Chinas Tianhe-1 has a computing speed of 2,507 trillion calculations a second, which makes it the fastest computer in the world. It is also 40 percent faster than the worlds second fastest supercomputer, Cray XT5 Ja
2、guar, in the US, housed at a national laboratory in Tennessee, according to the New York Times. Jack Dongarra, a University of Tennessee computer scientist who puts together the official supercomputer rankings, told NYT that the Chinese supercomputer “blows away the existing number one machine”.Buil
3、ding the fastest supercomputer has become a source of national pride, as these machines are valued for their ability to solve problems in areas like defense, energy and science. These problems are related to national interests. Supercomputing technology is also found in business. Oil and gas compani
4、es use supercomputers to find oil and gas. Wall Street traders use them for super quick automated trades. P&G even uses supercomputers to make sure that Pringles (品客薯片) can be put into cans without breaking. Obviously, research centers with large supercomputers are magnets (磁铁) for top scientific ta
5、lent. This adds extra significance to the machines theyre more than just huge calculators. Chinas new supercomputer will be used to speed up greatly large-scale scientific computations, such as hurricane and tsunami modeling, cancer research, car design and even studying the formation of stars.In 20
6、08, two US scientists put together a step-by-step guide on how to build a supercomputer using PlayStation 3 video-game consoles. Modern supercomputers are built by combining thousands of small computer servers and using software to turn them into one large computer. Really, any organization with eno
7、ugh material and technology can create a fast machine. The Chinese system follows that model by linking thousands upon thousands of computer servers. But the secret sauce behind the system and the technological achievement is Chinas own networking technology. “That technology was built by them,” Don

9、 greater than that of the US, but there is still a long way to go before we get there.”Passage outline Supporting detailsChina has developed the worlds fastest supercomputer.Chinas Tianhe-1 has a high computing speed, 71_ it the fastest computer in the world.72_ to Jack Dongarra, the Chinese superco
