MC2 Post 829 The King Is China's New World's Fastest Computer

World's Fastest Supercomputer 
Makes Debut in China

China has knocked the US off the Top Spot with the unveiling of a the most powerful 
Supercomputer in the world.


Now fully operational, it has set a new performance record of 2.507 petaflops, as measured by the LINPACK benchmark. It combines massively parallel GPUs with multi-core CPUs, and is based on 7,168 Nvidia Tesla M2050 GPUs and 14,336 CPUs.

The announcement marks the end of the US' dominance in supercomputing. The record was previously held by the AMD Opteron-based Cray XT5 Jaguar at the Oak Ridge National Laboratory.

As well as cutting down on size, the use of GPUs cuts the system's power requirements dramatically. While a 2.507 petaflop system built entirely with CPUs would consume over 12MW, Tianhe-1A consumes only 4.04MW.
