On November 18, the 54th top 500 supercomputing ranking came, and the strongest supercomputing was still the Summit, floating-point performance 200PFLOPS of the United States (2.0 billion times), and the second was the sister Sierra, performance 125PFLOPSof Summit supercomputing, and the Shenwei of China.In total, China still dominates the market with 227 units, while the United States has 118 supercomputing units

Compared with the supercomputing in June, the top 10 of the TOP500 has not changed in fact, ranking and performance have not been upgraded. The top two are supercomputing built by IBM and NVIDIA using power 9 processor and teslak V100 acceleration card, but with different scales. Summit supercomputing has 2.41 million cores, with peak performance reaching 200 pfops and Rmax performance of 148.6 pflos, while the second is Sierra peak performance of 125.7 PFlops, Rmax performance 94.6pflops.

Third, the fourth is China's Shenwei.


In terms of quantity, the number of supercomputing units in China's top 500 has increased by 8 compared with that in June, from 219 to 227, which continues to occupy an advantage in quantity, while the number of units in the United States has increased slightly from 116 in June to 118, but it is still at a historical low level, which is no longer as brave as that in quantity.

However, the U.S. is still not underestimated in terms of supercomputing power. In the end, the U.S. is still far ahead of other countries,118 supercomputing units account for 37.8% of the total computing power, while China only accounts for 31.8%

However, the speed of China's supercomputing catch-up is also accelerating. In June, the share of computing power of both sides was still 38.8% and 29.9%, and the gap is narrowing.

In addition to China and the United States, the number of supercomputing in other countries is much smaller. Japan, the third largest country, has 29, France 18, Germany 16, the Netherlands 15, Ireland 14, Britain 11, and other countries are single digits.

As far as manufacturers are concerned, Lenovo ranks first in the position of 174 TOP500 supercalculations, followed by 71 in the dawn of China, and 65 in the tide.

In terms of chips, 470 supercomputers in the top 500 use Intel's processors. The second is IBM power processor, with a total of 14. However, the first two are both IBM power processors, and three sets of supercomputers use AMD's processors. Two of them are the latest Xiaolong processors.
