"If you rebuild one from scratch, it's still too risky......"

Tu Jianfeng said.

"There is a risk, but the technical team we recruited from Eagle Sauce is still very experienced, and the risk can be controlled within a certain range, after all, we are about to launch a supercomputer with a speed of 2 billion operations per second, which is specially designed to help with nuclear fusion research. ”

Yang Jie said with a smile.

“......”

Tu Jianfeng and the others all opened their mouths wide-

Huaxing Group has built a set of supercomputers in order to study nuclear fusion technology, and the computing speed is now the world's most powerful supercomputer, which is really a luxury!

A supercomputer with such a high computing speed can process the same amount of data in a day as 6 billion people around the world have to calculate it for more than 90 years.

The computing performance of the supercomputer built by Aihua Technology Group is still 5000 trillion times, but after more than four years, Huaxing Group has increased the computing power of the supercomputer to 40 times!

Inspur Group, a subsidiary of the Chinese Academy of Sciences, also launched a supercomputer with the same performance six months later, and now the two companies have similar technical levels in supercomputers.

It is no wonder that Yang Jie himself studied under Academician Jin Minzhe, and some of the people in the R&D team are still from the National Parallel Computer Research Center, and many of the technologies are of the same origin.

Now the best in China in terms of supercomputers are Inspur Group and Aihua Technology Group Corporation, but Aihua Technology Group Corporation has done a better job in commercialization and has greater influence.

Simulating nuclear fusion requires extremely high computing performance of supercomputers, and the original domestic supercomputers can only simulate more than 10 billion particles at most when conducting nuclear fusion simulations, and it takes at least a few months to simulate a time, and it costs hundreds of thousands of yuan of electricity every day, and it takes tens of millions of dollars to simulate a simulation.

But now Huaxing Group has increased the computing speed of the supercomputer by 40 times, the time of a simulation can be shortened to several hours, and the number of particles that can be simulated can be increased to hundreds of billions, which basically meets the requirements of the "artificial sun" science and engineering.

Inertial confinement nuclear fusion is to compress the two particles of deuterium and tritium, which can produce fusion energy, to only one thousandth of the volume of the liquid of the same mass, confined to a core device similar to the size of peanuts, and then heated to a high temperature of 100 million degrees in nanoseconds without flying apart, in order to produce the fusion energy required for the scientific engineering of "artificial sun". For such extreme reactions, it is difficult for existing experimental detection methods to penetrate deep into the fusion fuel for measurement, and what is even more difficult is that these high-temperature plasmas are very difficult to control, and the plasma not only has a short interaction, but also a long-distance interaction, and its behavior is close to chaos, so it is very difficult to control.

Supercomputers are used to simulate and calculate the motion behavior of these particles to validate the theoretical models established by scientists, and at the same time to verify them through these experimental devices.

In the past, the computing power of supercomputers was not enough, so there was no way to simulate the motion of so many particles, and the computing power of supercomputers in the 80s and 90s was only petascale and quadrillion, which was completely insufficient to simulate nuclear fusion, and the simulated theoretical model of nuclear fusion was not accurate, and it could only be obtained through a large number of experiments to obtain various data to establish the model.

The use of supercomputer simulation, can be step-by-step to simulate each process, study the physical details, the stronger the computing ability, the higher the accuracy of the simulation, the faster the calculation speed, save a lot of time, is conducive to the design of the experimental device and the analysis and understanding of the experimental results, can be said to be a super tool.

There is no doubt that controlled fusion can bring nearly unlimited clean energy, and scientists have made steady progress in this area, but in fact the difficulty of fully controlling nuclear fusion has encountered several very big problems.

The Southwest Institute of Nuclear Industrial Physics now does not have a supercomputer, and the two supercomputer centers built by Huaxing Group Company are mainly used for their own use, and there are many projects applied by the National Supercomputer Center.

This time, Huaxing Group has set up a supercomputer center for nuclear fusion, which is very helpful for domestic nuclear fusion research.

The scientists at home and abroad who are developing "artificial suns" all dream of simulating through supercomputers, and they need supercomputers with higher performance and easier to use.

One of the most serious problems with tokamak devices is how to minimize or fully control the interruption of plasma flow, which requires scientists to be able to build a prediction model that can predict the interruption with 95 percent accuracy within 30 milliseconds before the plasma interruption occurs, so that the control system can adjust in a very short time to avoid the phenomenon of plasma interruption.

This is extremely difficult, only more than a billion times of supercomputers through the simulation of a very accurate software control system and high-precision and high-sensitivity probes for real-time adjustment, and nuclear fusion is very complex, this control system software must have intelligence and extremely high computing speed to be able to quickly and accurately solve complex problems, this can only rely on artificial intelligence deep learning.

The core technology of the stellarator and the tokamak is the same, the advantage is that the controlled plasma has no plasma current, so there is no risk of large rupture at all, and the operation is more stable, but it is also extremely difficult to fully control these unpredictable rampage plasma, and the difficulty is even greater than that of the tokamak, because the requirements of this device are very touching from processing to operation, and it is the configuration of high-end players, but the advantages are also obvious.

As with the tokamaks, it is necessary to build a very accurate mathematical model of the plasma turbulence of nuclear fusion in order to have a more accurate prediction of the impact path of these plasmas, but the stellarator is more difficult.

These two technical routes can't say who is right and who is wrong, it mainly depends on how everyone chooses, and now Eagle Sauce has given up the technical route of the stellar, leaving only two high-end players in Neon Country and Germany.

The technical team recruited by Yang Jie is engaged in the stellar simulator technology route, so it can only plunge headlong into the nuclear fusion technology route of the stellarator.

To this end, he deliberately built a set of special supercomputers for this one, and also applied artificial intelligence technology to speed up the progress of research in this area.
