Tianhe-I

The Tianhe -1A ( chinese天河 一号, Milky Way -1A ) is a Chinese supercomputer.

With a computing power of 2.56 petaflops (measured by the Linpack benchmark) sparked the Tianhe -1A in November 2010 the U.S. Cray Jaguar (1.76 petaflops ) and then the world's most powerful supercomputers from. In June 2011, this record of four times faster Japanese Fujitsu K computer ( 10.51 petaflops ) was exceeded.

With a power output of about four megawatts he is significantly more energy efficient than its predecessor at the top, the Jaguar at Oak Ridge National Laboratory ( about seven MW).

In June 2012, the Tianhe -1A was considered the fifth- fastest computer system in the world, behind the SuperMUC in Munich ( 2.9 petaflops ). The theoretical maximum output is 4.67 petaflops. The Tianhe -1A NVIDIA Tesla M2050 consists of 7,168 GPGPUs, each with 448 processor cores and 14,336 Intel Xeon X5670 CPUs with six cores. It was developed by the National University of Defense Technology and is available at the National Supercomputing Center in Tianjin. The operating system is a specially customized Linux distribution.

The successor system Tianhe -2 is approximately 13 -fold processing power ( 33.86 petaflops ) since June 2013 the world's most powerful supercomputers.
