Supercomputer 500 strong explain: Japan 7 years after the strong return

Supercomputer 500 strong explain: Japan 7 years after the strong return Yesterday evening, TOP500. The org organization announced the 37th ranking of the world's top 500 supercomputers. Japan’s K Computer took first place with more than 8 PFlops (8 petaflops per second) performance. After Japan’s Earth Simulator in November 2004, Japan returned to the top of supercomputing for the first time.

The new champion “Kyo” is located at the RIKEN Advanced Computing Research Institute (AICS) in Kobe, Japan. It was built by Fujitsu and uses 68544 SPARC64 VIIIfx processors clocked at 2.0GHz, each with eight cores and a total of 548,352 cores. It is twice the size of other supercomputers, and unlike China's Tianhe No. 1A, which is crowded into the top spot, it does not use GPU acceleration.

The name "King" comes from the Japanese "Kei" (a billion times), which represents the performance target of this supercomputer. The actual maximum performance is 8.162 PFlops (8.162 petaflops) and the peak performance is 8.77363 PFlops. Exceeded the sum of two to six, and the calculation efficiency is astonishing 93.0%. In addition, the total system power consumption of Beijing is 9898.56 kilowatts.

China's Tianhe No. 1 A slipped to No. 2 without any change. Its maximum performance and peak performance were 2.566 PFlops and 4.701 PFlops. We also learned that the exact power consumption was 4040 kilowatts. In contrast, Japan's "King" only consumed 1.45 times more power, and achieved 3.18 times the computational performance. It is one of the highest energy efficiency supercomputing systems.

Other points - For the first time in history, the top ten computing performance has exceeded the 1PFlops mark, but this is also the only 10 PFlops level supercomputers. What is very interesting is that the tenth name was the first American Roadrunner to reach the PFlops level three years ago.

- The top ten countries in the United States still occupy half of the country, Japan and China have two, and France one.

- The second China Tianhe No. 1 A, the fourth Chinese nebula, and the fifth Japanese Tsubame 2.0 all use the NVIDIA Tesla GPU for acceleration, and there are 19 such systems on the entire list.

- The number of supercomputers in China is still growing. Today, it has reached 62, leaving Germany, the United Kingdom, Japan, and France to second place. However, because "Jing" is far ahead, the runner-up belongs to Japan in terms of performance.

-The Intel processor continues to dominate, appearing in 387 supercomputers with a share of 77.4%. The 32nm Westmere Xeon 5600 series processor was used for 169 supercomputers, compared to 56 last year.

- The quad-core processor share has reached 46.2%, while 42.4% of systems use six cores or even more core processors, totaling nearly 90%.

- IBM still ranks first in terms of processor vendors, and Cray continues to lead Fujitsu in second place. The Cray XT system is still very popular among large scientific customers, with three out of the top ten.

The historical change - the top 500 threshold rose to 40.1TFlops, compared to 31.1TFlops six months ago.

- This year's 500th place can be ranked 262th half year ago, and the speed of the upgrade is obviously accelerating.

The -500 combined performance increased to 58.88 PFlops, compared to 43.7 PFlops six months ago and 32.4 PFlops a year ago.

The -500 has an average of 15,550 processor cores, compared with 13,071 a half years ago and 10,267 a year ago.

- The United States continued to lead with 256 units, but it was 18 less than six months ago, followed by 125 in Europe and 103 in Asia, of which the latter increased by 19 units. China increased from 42 to 62 and continued to rule in Asia, while Japan remained unchanged at 26. In Europe, Germany, the United Kingdom, and France are equal in strength, with 30 (+4), 27 (+3), and 25 (-1) respectively.

Power Consumption - It has been confirmed that 29 supercomputers consume more than 1 MW.

- The average energy consumption ratio is 248 MFlops/W, which is significantly higher than 219 MFlops/W six months ago and 195 MFlops/W one year ago.

- "Beijing" ranks first in performance, and the power consumption is also the highest, but energy consumption is better than first-class level.

The average power consumption of the -500 is 543 kilowatts, compared with 447 kilowatts six months ago and 397 kava a year ago.

- The average power consumption of the top ten players is 4.3 megawatts, and the average power consumption is 464 flops/W compared to 3.2 megawatts and 268 MFlops/W six months ago.
