Chinese Supercomputer Is Ranked Worlds Second-Fastest
A Chinese supercomputer has been ranked as the worlds second-fastest machine, surpassing European and Japanese systems and underscoring Chinas aggressive commitment to science and technology. The Dawning Nebulae, based at the National Supercomputing Center in Shenzhen, China, has achieved a sustained computing speed of 1.27 petaflops the equivalent of one thousand trillion mathematical operations a second in the latest semiannual ranking of the worlds fastest 500 computers.
The Chinese machine is actually now ranked as the worlds fastest in terms of theoretical peak performance, but that is considered a less significant measure than the actual computing speed achieved on a standardized computing test. The worlds fastest computer remains the Cray Jaguar supercomputer, based at the Oak Ridge National Laboratory in Tennessee. Last November it was measured at 1.75 petaflops. In the previous years ranking, the Chinese had the fifth-fastest computer, a system that was based at a National Supercomputing Center in Tianjin, China. That machine has now dropped to seventh place.
