Ultimate Scholar

Of course, it is said to be a run first, but before starting to run, of course, some preparations must be made.

At least the program needs to be written well.

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

In recent years, in terms of world supercomputing rankings, China’s list seems to have stopped updating. There has been no new supercomputer on the list. Sunway TaihuLight has dropped from the first place to the seventh position. .

It seems that China's supercomputing technology has come to an end, but this is not the case. This is because China has basically withdrawn from this international supercomputing competition and no longer participates in the ranking. At least there are new supercomputers built with official participation. I will no longer participate.

As for the reasons, there are different opinions. For example, there is no need to reveal their strength, or they are too lazy to participate in such foreign-established selections.

Of course, as far as Li Mu knows, not wanting to expose their strength is indeed a major reason, so that they can also hide their domestic chip development.

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

The more advanced the chip, the stronger the supercomputer processor and the higher the computing power. Like the supercomputers currently at the top of the list, each of these supercomputers has the best performance in the world. The strongest batch on the market, including in terms of manufacturing process.

The fact that Sunway TaihuLight can still occupy the seventh position with only a 28nm process is enough to prove that China's capabilities in supercomputer design cannot be underestimated.

It’s no wonder that some foreign experts speculated that the total computing power of China’s supercomputers was stronger than the sum of all supercomputers in other countries a few years after China stopped participating in supercomputing competitions.

"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 only then did he know that a very powerful supercomputer was built just under this base.

"We named it: Qilin Zhurui."

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

"It was built in 2021. In terms of computing power, Kirin Zhurui's computing power is equivalent to three times that of Sunway TaihuLight. It is mainly provided for use by our military scientific research base in East China, and its applicable range can be considered It is quite broad. In addition to material research, it also includes fluid calculations, such as DNS, mainly in these two directions. Others also take into account some meteorological predictions. We cooperate with the Pangu model of Warwick Company. The weather forecast is pretty accurate.”

Listening to Zhang Jianping's words, Li Mu couldn't help but marvel, "It's amazing, it's three times stronger than the Sunway Taihu Light."

"Of course, the Sunway Taihu Light was built in 2016. Our Qilin Zhurui will be built in 2021, so it will only be three times stronger."

Zhang Jianping laughed and said, of course, it can be seen that he is still very confident in supercomputing.

"Oh, by the way, because of the room-temperature superconductor you developed, Dean Li, I heard that the higher-ups have recently decided to start developing superconducting chips."

"Oh?" Li Mu raised his eyebrows, "I have heard that there is such a plan. Now is it confirmed?"

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

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

Once superconducting chips are born, the existing silicon-based chip system will inevitably suffer a huge blow. Just rely on superconducting chips. Don’t worry about the heating problem. When the time comes, the power and frequency will be fully maximized. The 28nm process The computing power of a chip may be higher than that of a 5nm process chip of the same area - of course, the only drawback of such a chip is probably its power consumption.

Li Mu nodded. Of course, he would not get involved in this aspect of research. He believed that other scientific research talents in China would definitely be able to break through those problems.

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

Eventually, they came to a computer and began preparing for the test.

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

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

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

Of course, since this new theory has only been around for a relatively short period of time, there is no mature application method yet.

"The principles of electronic behavior of materials have not been applied yet."

Li Mu asked after reading the program they wrote about material analysis.

"There's no way, after all, it hasn't been that long." On the side, Cheng Guodong spread his hands and said, "To be honest, I have been studying it for a while before, but in the end... you know."

Li Mu touched his chin and suddenly realized that the people around him were looking at him, and there was obviously a kind of expectation in their eyes.

Anyone with a discerning eye can see that these people are expecting him to say "It doesn't matter, I will take action."

He twitched the corners of his lips and said, "Okay, then leave it to me."

Unexpectedly, this task eventually fell on him.

Originally, he thought that after he figured out the theory, the rest of the work would be left to the academic circles.

"Okay, I'm just waiting for your words!"

At that moment, everyone around laughed. Cheng Guodong also patted Li Mu on the 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 using the old model to run it first.

Soon, I wrote all the programs, connected to the supercomputer, and began to use the super computing power of this Kirin Zhu Rui to start calculations.

Time passed quickly.

Until the end, the results came out.

"Hi~ Unbelievable."

A group of people gathered around a printed report, and then printed a report of FGH4098-15 using the same model. Once they compared the two, they all gasped.

Good guys, they're straight up good guys.

According to comparison, this brand-new material is about 15% stronger in various key properties, such as thermal strength.

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

At least, if they were given a choice, they would definitely choose this new material for the WS-22 fan blade material.

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

As for the performance in other aspects, basically needless to say, it is strong in everything that should be stronger. It can be called the hexagonal God of War in the aviation field.

However, these properties are only analyzed through calculations, and there is definitely no guarantee that they will be completely matched. But basically, the various properties of this new material are definitely better than the old materials.

"Dean Li, you have worked really hard."

Cheng Guodong shook hands with Li Mu firmly. With this new material, his confidence became much stronger.

But Li Mu just shook his head and said: "There is no need to thank me now. It is still a little difficult to actually produce this material."

Cheng Guodong also frowned, nodded and said, "That's true."

"This material has high requirements on the uniformity of elements, and how to improve the uniformity also has high requirements on the process."

Li Mu said: "So, in the next period of time, we need to work hard on technology."

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

"I think we can try some new techniques."

Li Mu touched his chin and said.

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

"A little."

Li Mu said.

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

"Okay, then let's start from two directions, and then we'll see who succeeds first." Cheng Guodong said with a smile.

"no problem."

Li Mu gestured "OK".

"Then what do you need?"

"The funds for the experiment, and the materials needed."

"These are all small things, we will prepare them for you." Cheng Guodong nodded.

"Okay, that's it."

Li Mu nodded.

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

"Well... let's just call it FGH5000. "

…

Naming and other things, for a material, it was easy to remember, and as the next work was determined, Li Mu no longer stayed, left the military scientific research base again, and returned to the Sheshan Research Institute.

Research on technology requires design and extensive experiments.

First, the new material, FGH5000, is synthesized based on the old process, that is, the process of FGH4098, and then compared through various analysis methods.

Facts have proved that even if the old process is used, the performance of 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 some important performances are also considered. The actual improvement is not much. For example, in terms of thermal strength, the increase is less than 1%. Naturally, there is no need to expand production.

Obviously, process improvements still play a decisive role.

"It must be admitted that precipitation hardening powder metallurgy is an excellent process and is of great help in improving uniformity. However, considering the principle of dispersion strengthening..."

Sitting at his desk, Li Mu thought about it for an unknown amount of time. Suddenly, his eyes lit up, and he took out a scratch paper and started theoretical calculations on it.

After just a moment, he stopped writing and said, "Yes!"

"Considering the formula of FGH5000, maybe, I can use granules instead of powder."

"However, wrapping the powder with metal particles, and then using the principle of dispersion strengthening, put new particles into it..."

"Yes, use aluminum to make hollow particles, and then evenly wrap other metal powders in proportion, then add nickel, chromium, cobalt and other hard particles to achieve dispersion strengthening, and then use precipitation hardening..."

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 used calculation methods to deduce the process he had thought of based on the theory of electronic behavior of materials. In this way, he supplemented and optimized various details in the process. .

till the end--

"Okay, that's it."

He wrote down the process flow he designed in detail.

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

I looked at the sky outside the window. It was already very dark.

pity.

As long as there is still some time, he will definitely do the experiment now.

"But it doesn't matter. Have a good rest tonight. The experiment will officially start tomorrow."

"It will definitely succeed!"
