Riding the wind of rebirth

Of course, supercomputers can also be used to solve nonlinear problems such as meteorological research and weather forecasting, atomic energy and nuclear reaction research, geophysical research, and earthquake analysis. However, because of the computing principles, when they deal with these problems, it is like using arithmetic to solve difficult equations, relying on hard calculations.

It can be done, but the algorithm design is complex, the calculation is huge, and it takes a long time.

Now Xiaozhi has surpassed Sugon-1000A in vector calculation, which is not its strong point. It has to be said that this is a miracle.

"It's normal to have such progress." Mai Xiaomiao looked at the numbers on the screen. "Because in our matrix computing power structure, the ability of a single-point computing unit is not high. It is a concept of comprehensive computing power. The ultimate super computing result is actually mainly due to the result transmission and mutual influence between computing power units."

"That is to say, the computing power of neurons themselves is not the focus of our system. We can make up for its weakness by using a huge number of them."

"This result can only be achieved through data exchange between a large number of computing units. Therefore, the speed of network exchange directly determines the computing efficiency of our system."

"The switches we used before were Motorola switches. After the first upgrade, we switched to 04 switches. Due to protocol limitations, a switch can only connect up to 255 nodes. We also have to consider the cost, which is quite restrictive when building a neural network."

"Now that we have switched to Ethereum FC, this limitation has been completely broken. We can use the expansion method of the Ethereum network to arbitrarily expand computing resources and achieve flexible resource allocation."

His hands were clacking at the keyboard, lines of code were scrolling on the screen, and Mai Xiaomiao commented as he typed: "Before, our network speed relied on a 20M switch for connection, but now it has been upgraded directly to 200M, which has improved the performance tenfold. It has also improved our Xiaozhi's vector computing by six times, which is not an exaggeration."

"Xiao Miao, what are you doing now?" Zhou Zhi couldn't help but ask when he saw Mai Xiaomiao typing code frantically.

"I'm rebuilding the system's dynamic balance and adjusting the core code." Mai Xiaomiao said, "We'll rerun the Navy uncle's cavitation model later to see how long it takes to get the results."

"It seems that the results of Xiaozhi's Go games are different every time, right?" Zhou Zhi had never paid much attention to this issue before, until one day he suddenly thought of a situation, that is, why every game of Go played by Xiaozhi is different. Even if he sometimes deliberately lets others use the same method, Xiaozhi's response method will also change, and ultimately lead to a variety of games.

"Yes, the calculation result given by Xiaozhi is not the optimal linear result, but the best way in terms of probability. Such probability not only includes the judgment of the current chess game, but also includes its learning results at different stages and its judgment of the subsequent chess game trends." Mai Xiaomiao explained with a smile: "Every time Xiaozhi plays a game of chess, it will learn new experience. It will no longer be the Xiaozhi before the game. So when it plays the same game again, its steps may be different from before."

"This seems to be different from the smart chess player currently being developed by the Go Institute and Samsung in South Korea?"

"Of course it's different. It's different from the intelligent chess players and IBM's Deep Blue. Although Deep Blue has been able to challenge top chess players, its thinking algorithm is still set, not autonomous."

Everyone stopped talking, and the only sound in the room was the clacking of keyboards. After a while, Elder Yu asked carefully, "Xiao Miao, is it an overkill for Xiao Zhi to use the model from the Ship Power Research Institute?"

"Well... I guess so." Mai Xiaomiao was honest and straightforward: "The model originally only used a small part of the computing power and was completed in the computing black box. It would be great if it could be used for more complex situations."

"How about we contact the Fengyun satellite team and see if we can use their deduction model to do a calculation?"

Meteorological simulation and weather forecasting are difficult problems all over the world. The saying that a butterfly flapping its wings in the Western Hemisphere can cause a storm on the sea in the Eastern Hemisphere refers to the complexity of meteorological simulation and the probabilistic discreteness of nonlinear motion trajectories.

Of course, as long as the data vector dimensions are sufficient and the computer is powerful enough, it can be deduced in theory. However, due to its unique discrete probability characteristics, the further the sample time is in the deduction, the greater the probability of the difference between the deduced result and the actual result will be.

In other words, the estimate may be reliable for one or two days, but the accuracy will start to deteriorate after three or four days. After a week, just listen to it for fun and don't take it seriously.

In order to obtain vector data of the largest dimension, powerful countries have launched satellites into space, established meteorological satellite business monitoring systems, and used remote sensing technology to monitor the earth from space.

In order to deal with the common enemy of all mankind, major natural disasters, an organization called the International Charter for Major Disasters was even established. Capable countries work together to implement a shift system and arrange satellites on duty.

Because every country puts its own interests first, meteorological satellites are generally deployed over their own countries to monitor weather changes within one-third or one-half of the earth within their own country. For example, China's current Fengyun-1A polar-orbiting meteorological satellite and Fengyun-2A geostationary orbit satellite will only observe typhoons around China and the eastern Pacific and Indian Oceans, and do not have the leisure to watch the tornadoes unique to North America on the other side of the earth.

The spy satellites of other countries are close to the earth and orbit around the earth. They are different from weather satellites.

Therefore, China, the United States and Russia actually each have their own surveillance areas, and when added together they can just monitor the entire earth and schedule duties, and the results can be shared by the whole world. This is basically the best cooperative project of human civilization so far.

After listening to Mr. Yu’s introduction, Zhou Zhi realized that there were so many interesting stories about meteorological satellites, and he couldn’t help but listen with great interest.

"Alright!" After Mai Xiaomiao entered the last line of code, he pressed Enter to compile it, then copied it to the specified directory and called it. Soon the numbers on the screen began to jump again. Although there was not much change in the peak value of the calculation data this time, the numbers below the peak value suddenly dropped sharply.

"What does this mean?" Li Laosan was anxious: "Why did all the performance drop? Is there something wrong?" (End of this chapter)
