Chinese supercomputer twice as fast as closest US rival
China’s showpiece Tianhe-2 computer is almost twice as fast as its nearest rival, according to a new ranking. But the simple benchmark used to rate the powerful “research and education tool” may not effectively measure the supercomputer’s true usefulness.
Tianhe-2, which means ‘Milkyway 2,’ can execute 33.86 petaflops per second. This is equivalent to 33,863 trillion calculations per second. The device, which uses US-designed Intel microchips, was turned on earlier this year and is being run by Guangzhou’s city government.
The internationally recognized Top500 ranking, which is twice-yearly compiled by scientists at the University of Mannheim, gives computers a specific type of mathematical equation which allows for direct comparison, known as the ‘Linpack benchmark.’
China’s National University of Defense Technology (NUDT) says that Tianhe-2 was developed for government security applications, various simulations, and analysis. Packed with 16,000 computer nodes, it has 3,120,000 cores. The total CPU plus coprocessor memory is 1,375 terabytes.
The interconnect system, operating system, front-end processors, and software were all developed by Chinese scientists. The system is the most energy-efficient configuration in the top 10, with 2.33 megawatts consumption of power that delivers 2.7 Gigaflops-per-watt of performance.
"The major challenge is for China to develop the computing chip technology so it can build the whole computer with Chinese parts. Application software also presents a great challenge," Jack Dongarra, professor at the University of Tennessee and Top500 editor, told Xinhua.
Tianhe-2, to be officially launched at the end of this year, is designed as a "research and education" tool. It can be used in a variety of China’s commercial industries and in a number of research fields that need to process a lot of raw data, such as physics.
The $390 million mega-system can multitask and is able to operate traffic lights, predict earthquakes, be used in pharmaceutical and car industries, and create movie special effects, Xinhua reports.
Tianhe’s nearest rival, the two-year-old Titan at the Oak Ridge National Laboratory, has a capacity of 17.59 petaflops per second.
"The Tianhe-2 is a very powerful computing system," Dongarra said. "It has almost two times the performance of the number 2 system, Titan. I wouldn't be surprised if it was in the number 1 position for another year."
Despite being far behind – and also with no record-breaking supercomputers in the pipeline for the next couple of years – the US can still console itself with five places in the top 10, and with 265 in the top 500. China is in second place with 63 supercomputers in the top 500.
According to the updated list, the combined performance of all 500 systems is 250 petaflops per second. The top 17 systems on the list are responsible for half of the total performance, with the other half sharing the total performance between 483 systems.
Europe appears to be falling behind, with 102 computers on the list – 10 less than six months ago. Russia’s leading supercomputer, located at Moscow State University, and is ranked 37th.
But the scientists behind the project are increasingly aware that a theoretical benchmark is a poor reflection of the usefulness of supercomputers in solving specific tasks for which they are constructed, and in no way measure whether a supercomputer is being used productively.
"A very simple benchmark, like the Linpack, cannot reflect the reality of how many real application perform on today's complex computer systems," said Erich Strohmaier, one of the authors of the Top500.
"More representative benchmarks have to be much more complex in their coding, their execution and how many aspects of their performance need to be recorded and published. This makes understanding their behavior more difficult.”

World's fastest supercomputer starts formal operations
English.news.cn 2013-11-20 19:33:04
GUANGZHOU, Nov. 20 (Xinhua) -- The world's fastest supercomputer, the Tianhe-2, began formal operations on Wednesday at the National Supercomputing Center in Guangzhou in south China.
The supercomputer, capable of performing 33.86 petaflops per second (Pflop/s), was at the top of a Top 500 list ranking the world's fastest supercomputers, which was released at the SC13 supercomputing conference in Denver on Nov. 18.
Developed by the National University of Defense Technology in June, the supercomputer was shipped to Guangzhou, capital of Guangdong Province, in September and installed and tested for more than a month, according to sources with the supercomputing center.
Tianhe-2, which means "Milky Way-2" in English, has been successfully tested in various applications, such as weather forecast, commercial airplane design, and gene sequencing, the center said.
It is almost twice as fast as the next computer on the list, the U.S. Department of Energy's Titan, which has a performance of 17.59 Pflop/s.

Wait until we roll out the Godson 3B1500 cpu in our supercomputer. It has great potential in the high-end server due to its unique chip MIPS-base architecture that reduce instructions and is less complex, leading to better theoretical performance efficiency than X86 base Intel.
We just need to shrink the chip size to the latest 22 nanometers but possibly catching up to Intel's 14 nanometer technology by the end of 2020s.

How China make use of these supercomputers isn't any of your concern. Don't act as a sour loser, you almost sounded like India know how to make the best use of it. I sense jealousy in your post lol

Some countries are enthusiastic about their inventions, they boast their things infront to world to show that they are progressing fast.
you are not supposed to tell me what concerns me and how I should act.....its none of your business and this is not your CCP mouthpiece.....if u cant dont ve techincal answer, keep shut and get lost....dont ever quote me to talk non sense like sour loser....if I start it my way, only Mod can save your arse!..u get me chindi chor?

Feeling personal attacked? If you can't take it don't start it in the first place. IF you are allowed to criticize China's performance so can we respond to your personal attacks.
did you get my first comment at first place? go and read it again...and then come back...i reiterate...u dont need to tell me how I shud act....if u dont ve the techincal answer, get lost or keep quoting for ur 2 cents....in that case u wont even deserve my response....
