Chinese Edge Toward Supercomputer Record
A Chinese supercomputer has been ranked as the world's second-fastest machine, underscoring China's 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 in the latest latest Top500 semiannual ranking of the world's fastest 500 computers.
The newest ranking was made public on Monday (May 31) at the International Supercomputer Conference in Hamburg, Germany. The world's 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.
The United States continues to be the dominant maker of supercomputers, and is the nation with the most machines in the Top500. But China appears intent on challenging American dominance. "I wouldn't be surprised if by the end of this year they surpass the scientific computing power of the E.U. countries combined and have a computer system with an achieved performance to reach the No. 1 position on the top 500," says Jack Dongarra, a computer scientist at the University of Tennessee and one of the researchers who has organized the twice-yearly rankings.
