China to Crack Supercomputer Top Ten List

jsse writes "ComputerWorld (Hong Kong) has an article about Chinese Academy of Sciences building a supercomputer which has been shown in benchmark tests to process up to 10 trillion floating-point operations per second (TFLOPS) and is expected to take a spot on the list of the world's ten most powerful supercomputers for the first time. The computer is a cluster of 2,560 Opteron 800 series processors from Advanced Micro Devices Inc. (AMD) contained in 640 nodes of four processors each. AMD has announced the project last year when the cluster was building."
