[Global Network Technology Reporter Chen Jian] China now surpasses the United States and has the world’s top 500 fastest supercomputers. According to the latest Super500 Top500 survey, China has 202 of these supercomputers, compared with 143 US elections.
The United States is currently defeated for the first time in the biennial Top 500 study, but it is still in second place, but it has reached its lowest level in 25 years. The third place is Japan, with 35 stations, and Germany is ranked fourth with 20 stations. It is worth noting that in the previous survey announced in June this year, the United States still had 169 supercomputers ahead of 160 in China.
Studies show that the increase in investment in supercomputers is the main reason why China surpasses the United States. China’s investment in supercomputer R&D has increased. China’s R&D expenditures account for about 20% of global R&D expenditures.
A supercomputer is a very large computer. Has a strong ability to calculate and process data, the main features of high speed and large capacity, with a variety of external and peripheral devices and a rich, highly functional software system. Often refers to a computer consisting of hundreds of thousands or even more processors (machines) capable of computing large and complex subjects that cannot be accomplished by ordinary PCs and servers for performing specialized, computationally intensive tasks. .
For example, current supercomputers are widely used in climate change research, nuclear weapon simulation, petroleum exploration, weather forecasting, DNA sequencing, and simulation of biomolecules.
Supercomputers usually measure performance in petaflops (petodes per second). At present, China’s fastest supercomputer, Shenwei Taihuguang, has maintained the fastest speed in the world at 93 petaflops. The United States ranked fifth in the Titans world, with a maximum performance of 17.63 petaflops.
The author of the list said that the latest data also shows that China has surpassed the United States in overall performance, accounting for 35.4% of the total processing capacity, compared with 29.6% in the United States. One of the co-founders of the survey, Erich Strohmaier, told the BBC that many Chinese systems were created to make money. The owners rented out their processing capacity to local and international companies.
He added: "There are two reasons for pursuing the performance ranking of supercomputers. First, just as the United States has always been in a leading position in the past, this is a prestige that a country leads in scientific research and development. Another point is supercomputers. Primarily for scientific exploration and national security, such as these systems are used for calculations related to weapons systems."
Water-cooled capacitor is supercapacitor is a capacitor with a capacity of thousands of farads.According to the principle of capacitor, capacitance depends on the distance between the electrode and electrode surface area, in order to get such a large capacitance, as far as possible to narrow the distance between the super capacitor electrode, electrode surface area increased, therefore, through the theory of electric double layer and porous activated carbon electrode.
