As we all know, with the development of science and technology, the world is becoming more and more dependent on supercomputers, because all high-tech has to be stacked with computing power, and supercomputers are the most powerful computing power.
To take the simplest example, in order to develop its own self-driving technology, Tesla even built a supercomputer of its own, which was once able to rank among the top 10 in the world in terms of performance, and used such a powerful supercomputer to develop algorithms.
On supercomputers, the computing power is tens of trillions per second, and its metric is FLOPS, which measures the number of fluctuating calculations that the CPU can perform per second, while the performance of the fastest supercomputer is measured in exaflops, which refers to 10 billion exaflops.
China's first supercomputer was Tianhe-1, released in 2009, using Intel's CPU and AMD's GPU, with a performance of 1,206 megabits per second, ranking fourth in the world at the time.
Later in 2013, China launched the Tianhe 2 with a performance of 5 per second4.9 billion (5.4 billion.)9pflops), which was the world's fastest supercomputer in 2013. And from 2013 to 2016, it won the TOP500 for 6 consecutive times.
Originally, it was planned to upgrade Tianhe 2 in 2017, but later because China's supercomputer was too strong, the United States was a little worried, and since 2015, Intel and AMD have been banned from selling supercomputing chips to China, so the upgrade has been delayed.
Even later, China began to develop domestic processors to replace Intel's chips, after all, you can't do without Intel's chips, and supercomputers won't do it.
And based on the domestic Shenwei CPU, Shenwei. Taihu Light was released, using a 40960 Shenwei 26010 processor, and its peak performance reached 12500 million exascale seconds (125pflops) has also won the world's first many times.
Recently, the upgraded version of Tianhe 2 was officially released at the 2023 Supercomputing Innovation and Application Conference, named "Tianhe Xingyi", which was released by the National Supercomputing Guangzhou Center.
This generation of supercomputers, abandoning Intel's CPU, uses a domestic processor, up to 1597440,000 cores, so how strong is the performance?
The data shows that its peak performance has reached 620pflops, that is, 6.2 billion billion times, which exceeds the Sunway Taihu Light, and even about 5 times that of the Taihu Light, ranking first among all domestic supercomputers currently announced.
Top 5 of the latest TOP500 super list.
However, compared with the strongest supercomputer in the United States announced by TOP500 some time ago, it is still a little far away, as shown above, the world's No. 1 American frontier, its performance is as high as 1194pflops, which is about 2 times that of Tianhe Xingyi.
If you take Tianhe Xingyi to rank, it can rank second in the world, because it is 585 more than the second-place aurora34pflops to be strong.
