A computer built by Chinese firm Dawning Information Industry is expected to be one of the world's 10 most powerful supercomputers.

The TC4000A is a cluster of 2,560 Opteron 800 series processors from Advanced Micro Devices (AMD) contained in 640 nodes of four processors each.

The computer, which was built earlier this year for the Chinese Academy of Sciences, has been shown in benchmark tests to process up to 10 trillion floating-point operations per second (TFlops), according to Patrick Wang, associate vice-president of Tyan Computer, which provided the motherboards used in the computer.

That level of performance would rank the TC4000A the ninth most powerful computer in the world, based on the existing ranking of the world's top 500 supercomputers maintained by the US National Energy Research Scientific Computing Centre, the University of Tennessee and the University of Mannheim.

The highest-ranked Chinese supercomputer so far is Lenovo Group's DeepComp 6200, which is also owned by the Chinese Academy of Sciences. The Itanium 2-based DeepComp 1800 ranks 14th on the list of the top 500 supercomputers.
