China has more than 100 more supercomputers than the United States, according to Top500

China is home to 219 supercomputers worldwide, while the United States has 116, according to the latest report from the Top500. But the two most powerful supercomputers are always Summit and Sierraowned by IBM in the United States.

Supercomputers, huge computing machines, are used in resource-hungry programs such as quantum physics, climate change prediction, engine and aircraft design, reconstruction of the history of the planet. Universe and the examination of the possibility of the explosion of old nuclear weapons.

The Top500 ranking, which ranks the world's best performing computer systems twice a year, is the only petaflop system to feature for the first time in the list.

"The total overall performance of all 500 systems has now risen to 1.56 Exaflops," said Top500.

China took the third and fourth most powerful supercomputer positions, with Sunway TaihuLight and Tianhe-2A (Milky Way-2A). They were developed respectively by the Chinese National Research Center on Engineering and Parallel Computing Technology and by the China National Defense Technology University.

Another American supercomputer took fifth place. Frontera, Texas, is the newest member of the world's top 10. Switzerland, Japan and Germany also house supercomputers ranked in the top 10.

There are 29 of the 500 largest supercomputers in Japan, 19 in France, 18 in the United Kingdom, 14 in Germany, 13 in Ireland and the Netherlands, eight in Canada and five in Singapore.

Intel now provides 96% of all supercomputers, said the Top 500.

In terms of "green" supercomputers, the Shoubu B system in Japan has been rated as the most energy efficient.

the the fastest supercomputer is expected to arrive in the United States in 2021 in the form of a new entrant called Frontier, a $ 600 million machine with Cray and AMD technology.

Frontier should be able to perform 1.5 billion calculations per second, a level called 1.5 exaflops and enough to claim the crown of performance, announced the US Department of Energy in May.

Since, Hewlett Packard Enterprise (HPE) announced the acquisition of Cray and consolidate their supercomputer power.

Cray is responsible for 39 supercomputers on the list, against 40 for HPE. Together, they would outnumber the second-largest manufacturer Inspur, which has 71 supercomputers on the list, but not the first Lenovo, which holds by far the majority, 173.

Monday, Nvidia also unveiled the DGX SuperPOD supercomputer, which will be the 22nd fastest in the world. It will be used to form the algorithms and networks of neurons used for the development of autonomous vehicles.
