Of course, it's said to run first, but of course, there is still some preparation to be made before you start running.

At least the program needs to be well written.

As for which supercomputer to run on, there is no need to worry.

In recent years, in the world supercomputer rankings, their list of Huaguo seems to have stopped updating, and there has been no new supercomputer on the list, and Sunway Taihu Light has fallen from the first to the seventh position.

It seems that Huaguo's supercomputing technology has come to an end, but in fact, it is not, this is because Huaguo has basically withdrawn from the evaluation of this international supercomputer and no longer participates in the ranking, at least the new supercomputer that the official participated in the construction will basically not participate.

As for the reason, there are different opinions, such as the lack of need to show strength, or the laziness to participate in this kind of foreign-established selection.

Of course, as far as Li Mu knows, not wanting to expose their strength is indeed a major reason, which can also hide their domestic development in chips.

After all, among supercomputing, the most important thing is the chip.

The more advanced the chip, the stronger the supercomputing processor, the higher the computing power, like the supercomputing currently at the top of the list, these supercomputing are counted as one, and the performance of the processor chip can be called the strongest batch in the world, including the process.

The fact that Sunway Taihu Light can still occupy the seventh position with only 28nm process is enough to prove that Huaguo's ability in supercomputer design should not be underestimated.

It is no wonder that some foreign experts speculated that the total computing power of China's supercomputing power was stronger than that of all supercomputing in other countries combined, a few years after China no longer participated in the supercomputing competition.

"This is our supercomputer room."

Under the leadership of Academician Cheng and others, Li Mu entered the underground of this military scientific research base, and at this time he also knew that a supercomputer with very strong performance had been built under this base.

"We named it: Kirin Zhurui."

Zhang Jianping, the management director of this supercomputer, introduced it to Li Mu with a smile.

"Built in 2021, in terms of computing power, Kirin Zhurui's computing power is equivalent to three times that of Shenwei Taihu Light, which is mainly provided to our military scientific research base in East China, and the scope of application is quite wide, in addition to material research, it also includes fluid calculations, such as DNS, mainly in these two directions, and others also take into account some meteorological predictions, we have cooperation with Warwick's Pangu model, and the meteorological prediction is quite accurate."

Listening to Zhang Jianping's words, Li Mu couldn't help but be amazed, "It's amazing, it's actually three times stronger than the light of Shenwei Taihu Lake." ”

"Of course, the light of Shenwei Taihu Lake was built in 2016, and our Qilin Zhurui will be built in 2021, and it will be three times stronger."

Zhang Jianping said with a smile, of course, it can be seen that he is still very confident in supercomputing.

"Oh yes, because of the room-temperature superconductor you have researched, Dean Li, I heard that the above has decided to start developing superconducting chips recently."

"Oh?" Li Mu raised his eyebrows, "I've also heard that there is such a plan, and now it has been confirmed?" ”

"Yes, it's confirmed, and the research on superconducting quantum computers has also begun, and room temperature superconductors are also very helpful for the development of quantum computers."

Zhang Jianping sighed: "I see, after all these projects are realized, we will be the strongest in the world in terms of computers, and we will also be in terms of chips." ”

Once the superconducting chip is born, the existing silicon-based chip system will inevitably suffer a very huge blow, just rely on the superconducting chip do not worry about the problem of heating, when the time comes, the power will be directly full, the frequency will also be full, the 28nm process chip, maybe the computing power is stronger than the same area of the 5nm process chip performance - of course, the only disadvantage of such a chip is probably power consumption.

Li Mu nodded, of course, he didn't get involved in this kind of research, and I believe that other scientific research talents in Huaguo will definitely be able to break through those problems.

Otherwise, even if he joins, he won't be able to do better.

最终，他们来到了一台电脑前，然后开始了测试前的准备。

The use of computer methods to study materials science is also the main method of computational materials science.

After the rise of this research direction of materials science, density functional theory is the theory mainly used by various computational materials scholars.

However, with the advent of the principle of electronic behavior of materials, many scholars in computational materials science have begun to optimize the methods of computational materials based on this new theory.

Of course, since the birth of this new theory is still relatively new, there is no mature application method at that time.

"Haven't you used the principle of electronic behavior of materials yet?"

Li Mu asked after reading the procedures they had written on material analysis.

"It can't be helped, after all, it's only been a long time." On the side, Cheng Guodong spread his hands and said, "To be honest, I have studied it for a while before, but in the end...... You know. ”

李牧摸了摸下巴，忽然发觉周围的人都在看自己，而这些人的目光中，显然都透露着一种——期待。

Anyone with a discerning eye can see that this group of people is expecting him to say, "It doesn't matter, I'll make a move".

He tugged at the corners of his mouth and said, "Okay, then leave it to me." ”

Unexpectedly, this task ended up falling on my head.

Originally, he was still thinking that after he came up with the theory, the rest of the work would be left to the academic community to do it themselves.

"Okay, just wait for your words!"

At that moment, the people around laughed, and Cheng Guodong also patted Li Mu's shoulder and said with a laugh.

Li Mu shook his head helplessly.

Of course, although this task has been given to him, it does not prevent them from running with the old model first.

Soon, I wrote all the programs, and then connected to the supercomputer, and began to use the super computing power of this Kirin Zhurui to calculate.

Time passed quickly.

Until finally, the results came in.

"Hiss~ unbelievable."

A group of people gathered in front of a printed report, and then printed the results of a report of FGH4098-15 running out with the same model, and once the two were compared, they all gasped.

Good guys, they're straight good guys.

In comparison, the new material is about 15% stronger in terms of key properties, such as thermal strength.

Based on this alone, the superiority of this material in the field of aviation far surpasses that of FGH4098-15.

至少，如果让他们选择的话，到时候在WS-22的扇叶材料上面，肯定会选择这个新的材料。

Of course, the premise is that they can synthesize this new material.

As for the performance in other aspects, there is basically no need to say much, the stronger places are stronger, and it can be called the hexagonal god of war in the aviation field.

However, these properties are only analyzed by calculation, and they are certainly not guaranteed to match exactly, but basically, the properties of this new material are definitely better than those of the old material.

"Dean Li, it's really hard work."

Cheng Guodong shook hands with Li Mu heavily, and with this new material, his confidence has increased a lot.

But Li Mu just shook his head and said, "There's no need to thank me now, there is still a little difficulty in really getting this material out." ”

Cheng Guodong's brows also furrowed, nodded and said, "That's true." ”

"This material has higher requirements for the uniformity of the elements, and how to improve the uniformity has greater requirements for the process."

Li Mu said: "Therefore, in the next period of time, we need to work the technology. ”

"Yes, for now, there is still room for improvement in our powder metallurgy process, and we are now considering continuing to develop this process."

"I thought I could try some new processes."

Li Mu touched his chin and said.

"Do you have any ideas?" Cheng Guodong asked.

"A little."

Li Mudao.

He found some inspiration in the synthesis of superconductors at room temperature, and maybe he could give it a try.

"Okay, then let's start from two directions, and then see which of us succeeds first." Cheng Guodong said with a smile.

"No problem."

Li Mu compared "OK".

"Do you have any needs?"

"Funding for the experiment, and the materials needed."

"These are the little things, and we'll get them ready for you." Cheng Guodong nodded.

"Okay, that's it."

Li Mu nodded.

"By the way, how do we name this new material?"

"Hmm...... Then just call FGH5000. ”

……

Naming something, for a material, it is easy to remember, and with the determination of the next work, Li Mu will not stay longer, and once again left this military scientific research base and returned to Sheshan Scientific Research Institute.

The research on the process needs to be solved by the method of design and a large number of experiments.

First of all, according to the old process, that is, the FGH4098 process, the new material is FGH5000 synthesized first, and then compared through various analysis methods.

Facts have proved that even if the old process is used, the performance of the FGH5000 is still better than that of FGH4098-15, but there are not many excellent ones, it can only be said that the comprehensive improvement is estimated to be less than 2%, and then consider the actual improvement of some important performance, such as thermal strength, the increase is less than 1%, and there is naturally no need to expand production.

Obviously, the improvement of the process still plays a decisive role.

"It must be admitted that precipitation hardening powder metallurgy is a very good process method, which is of great help to improve uniformity, but considering the principle of dispersion strengthening......

Sitting at the desk, Li Mu thought about it for an unknown amount of time, and suddenly, his eyes lit up, and then he took out the scratch paper and began to calculate theoretically on it.

After only a moment, he stopped his pen and said, "There you go!" ”

"Considering the FGH5000 formulation, perhaps, I can take granules instead of powders."

"However, the powder is wrapped in metal pellets, and then new particles are injected into it using the principle of dispersion strengthening......"

"Yes, hollow particles are made of aluminum, and then other metal powders are evenly wrapped in proportion, and then hard particles such as nickel, chromium, and cobalt are added to achieve the purpose of diffusion strengthening, and then the method of precipitation hardening is used......"

Of course, just such a fantasy is definitely not enough, it must be combined with theory.

So, Li Mu immediately picked up the pen, and then according to the theory of the principle of electronic behavior of materials, he used the method of calculation to deduce the process he thought of, and in this way, the various details in the process were supplemented and optimized.

Until the end -

"Okay, that's it."

The process he designed was written in detail.

With all the theoretical work completed, Li Mu stood up from his seat and then stretched.

Looking out the window, it was already dark.

Pity.

If there was still some time, he would definitely go to the experiment now.

"But it doesn't matter, have a good rest tonight, and start the experiment tomorrow."

"It will work!"
