China claims supercomputer crown
« on: November 01, 2010, 06:26:50 am »

China has claimed the top spot on the list of the world's supercomputers.

The title has gone to China's Tianhe-1A supercomputer that is capable of carrying out more than 2.5 thousand trillion calculations a second.

The Tianhe-1A supercomputer is about 50% faster than its closest rival.

To reach such high speeds the machine draws on more than 7,000 graphics processors and 14,000 Intel chips.

The claim to be the fastest machine on the planet has been ratified by the Top 500 Organisation which maintains a list of the most powerful machines.

High power
China's Tianhe-1A (Milky Way) has taken over the top spot from America's XT5 Jaguar at the Oak Ridge National Laboratory (ORNL) in Tennessee that can carry out only 1.75 petaflops. One petaflop is the equivalent of 1,000 trillion calculations per second.

The news about the machine broke just before the publication of the biennial Top 500 Supercomputer list which ranks the world's most powerful machines.

Prof Jack Dongarra from the University of Tennessee, one of the computer scientists who helps to compile the list, said China's claim was legitimate.

"This is all true," he told BBC News. "I was in China last week and talked with the designers, saw the system, and verified the results."

He added: "I would say it's 47% faster than the Oak Ridge National Laboratory's machine, 1.7 Pflops (ORNL system) to 2.5 Pflops (Chinese system)."

Tianhe-1A is unusual in that it unites thousands of Intel processors with thousands of graphics cards made by Nvidia.

The chips inside graphics cards are typically made up of smaller processing units that can carry out a limited set of arithmetical oeprations very quickly. By contrast, Intel processors for desktop machines are typically capable of carrying out much more complicated mathematical operations.

The machine houses its processors in more than 100 fridge-sized cabinets and together these weigh more than 155 tonnes.

Based in China's National Center for Supercomputing in the city of Tianjin, the computer has already started to do work for the local weather service and the National Offshore Oil Corporation.

I wonder what else they use it for? 155 tonnes! I wonder what the portable version looks like.  :lol:

...could you imagine what a group like the blender foundation (or pixar & dreamworks) could do with this monster?

China has the fastest Super Computer that is made with all American technology. It uses Intel XEON's and NVIDIA GPUs both American companies.

I wonder when an American institution will do the same thing and I also wonder when China will begin designing their own high performance chips for there own super computers. For a nation that values independence and has often been outspoken about why they don't need western technology they sure utilise it a lot when it suits them.
