Fastest computer breaking records

BEIJING - China's Tianhe-1 computer has overtaken China's Nebulae to take the top fast computer spot, according to a new list of the country's top 100 supercomputers released on Thursday.

Back in June, the Nebulae was in second place in the world, after the United States' Jaguar system, while the Tianhe-1 was in a lowly seventh place on the biannual world TOP 500 list.

The Tianhe-1 (Chinese for Milky Way) is in the National Center for Supercomputing, in the port city of Tianjin. It has a sustained computing speed of 2,507 trillion calculations per second. That is 2.507 petaflops per second (PFlop/s), with one petaflop equivalent to 1,000 trillion calculations per second.
