Once again, China dominated a new list of the world's fastest supercomputers, not only taking the top two seats, but also pulling ahead of the United States in the sheer number of systems being used.

According to a biannual ranking of the world's 500 fastest supercomputers, called the Top500 published Monday, China's Sunway TaihuLight maintains the lead as the No. 1 system for the fourth time, with a performance of 93.01 petaflops.

China's Tianhe-2, or Milky Way-2, is still the No. 2 system at 33.86 petaflops. Intel chip-based Tianhe-2 had topped the list for three years until it was displaced in November 2015 by TaihuLight, which was built by entirely using processors designed and made in China.

The No. 3 is Switzerland's Piz Daint, which is also the most powerful supercomputer in Europe. A new system in Japan, called Gyoukou, is the No. 4, pushing Titan, the top U.S system, to the No. 5.

"For the second time in a row there is no system from the U.S. under the TOP3," Top500 said in a statement.

And that's not all. The 50th edition of Top500 ranking also shows that China has overtaken the United States in the total number of ranked systems by a margin of 202 to 144. Just six months ago, the United States. led with 169 systems, and China with 159.

"It is the largest number of supercomputers China has ever claimed on the TOP500 ranking, with the U.S. presence shrinking to its lowest level since the list's inception 25 years ago," Top500 said.

"China now clearly shows a substantially larger number of installations than the United States."

China has also overtaken the United States in aggregate performance as well. The Asian country now claims 35.3 percent of the TOP500 flops, with the United States at second place with 29.8 percent.

The Top500 list is considered one of the most authoritative rankings of the world's supercomputers. It is compiled on the basis of the machines' performance on the Linpack benchmark by experts from the United States and Germany.
