The top student must be diligent

After all, it’s hard not to be happy with such a large amount of business coming just at the beginning of the new year.

At this time, Xiao Yi continued to ask: "Manager Yu, my situation has changed now, and I plan to expand a batch of 3 million servers."

Upon hearing what Xiao Yi said, Manager Yu's eyes lit up and he clapped his hands and said, "Of course it's no problem! I'll arrange it right away!"

"Mr. Xiao, it's a coincidence that you're here. Our business has just opened this year, and a batch of servers just happened to be shipped over. Otherwise, you might have to wait for a while."

Xiao Yi smiled: "Then I'll bother Manager Yu."

"No trouble, no trouble." Manager Yu waved his hand, but then he asked: "But having said that, I would like to ask, Mr. Xiao, what did you buy this server for? These 5 million servers are not enough "

"Of course, if it's not convenient for you to say it, forget it."

Xiao Yi waved his hand: "It's not inconvenient. The main thing is that we have developed a mining software, mainly for users. It will be officially open for download in the next period of time. The usage of this software will increase a lot. A 5 million server cluster may not be enough.”

"Is it actually mining software? It does take up a lot of space." Manager Yu was surprised, then he thought about it and said, "Then I only have two suggestions, buy more server clusters, this As for the space required, another suggestion is to cooperate with some other server companies, such as data centers, they have server hosting related business, you just need to ensure the security of the software algorithm. "

"Data center?" Xiao Yi thought for a moment: "I understand, thank you for your suggestion."

"Of course, another possibility is that your software is really popular and attracts investment from other companies. In this case, you can select companies that can help you on the server for financing." Manager Yu Said: "I just heard you mention 200,000 mining machines on the phone. It should be referring to 200,000 mining machines, right? If that is the case, then your software is amazing, and the valuation is worth it at least. Hundreds of millions.”

Xiao Yi was stunned when he heard what the other party said.

He had never considered financing before.

But now that I think about it, after all, it is an innovation and entrepreneurship, and financing is indeed a normal method.

At this time, Xu Ming and Liu Chao came back. After hearing their conversation, Xu Ming said: "Brother Xiao, if you ask our senior sister for help with this kind of thing, she will definitely have a way."

Liu Chao also nodded: "Yes, our senior sister has a wide network of contacts. She seemed to have said before that she has an acquaintance who is working on some kind of data center, and she is thinking about when to get a server from that acquaintance."

As a result, when Cao Cao Cao Cao arrived, a voice came in: "What are you talking about? What do I want to cook?"

Xu Ming and Liu Chao were immediately frightened. When they turned around, they saw Luo Mingya coming over.

Okay, okay, I didn't mean to say bad things just now. They have been cleaning the house in the past few days.

"Sister, why are you here?"

"Didn't you say that the server that Junior Brother Xiao bought has arrived? I'll come over to see when we can use it." Luo Mingya said.

Manager Yu next to him smiled and said: "It will be available soon. Once these servers are configured and formed into a cluster, it will be ready."

Luo Mingya nodded, and then she turned to look at Xu Ming and Liu Qun.

"What did you just say I could do to help Xiao Yi?"

Xu Ming and Liu Qun looked at Xiao Yi again.

Xiao Yi told what happened just now.

"This matter..." Luo Mingya thought for a moment, then nodded: "I can really help with this. My brother is in the data center. If you ask him to cooperate, there will be no problem. His data center It’s just in Jinling, not too far away.”

Xu Ming said: "Huijing is great. It's actually in the capital of our province. It's okay."

Everyone laughed. As we all know, Jinling is the capital of their Hui Province, and is nicknamed Hui Jing.

"I'll give him a call directly. It just so happens that his data center hasn't been built for a long time. If there is business coming, he will probably be happy."

Then, Luo Mingya took out her mobile phone and made a call.

Soon, the call came through.

"Luo Mingchuan, come to my school and introduce a business to you."

Listening to the way Luo Mingya talked to his brother, Xu Ming and the others showed expressions of no surprise.

Well, no surprise!

Soon, Luo Mingya hung up the phone, turned to Xiao Yi and said, "Okay, my brother will probably arrive this afternoon."

Xiao Yi immediately smiled and said: "Thank you very much!"

Liu Chao next to him asked curiously: "Sister, since your brother is engaged in data center, why don't we directly ask him for help?"

Luo Mingya waved his hand and said: "The data center is just a data center, not a computing center, and there is no high-performance computing. Our research mainly requires stronger computing power. If you really want to ask him for help, then I will It’s better to go to another calculation center to calculate it faster.”

"That means you have to queue up to use a supercomputer. Otherwise, I would definitely use a supercomputer."

Liu Chao nodded in realization.

Next, they waited for the masters to install the server and then turned on the server directly.

"Let's try running for a while now, Junior Brother Xiao, is that okay?"

Luo Mingya turned to ask Xiao Yi.

"Of course, no problem." Xiao Yi said.

"Okay, thank you."

Luo Mingya nodded, then she took out her laptop, connected to the server, opened their algorithm, and started running.

The server cluster worth 5 million started running, and all the computing power was mobilized to start calculating this algorithm model.

Their algorithm was deeply optimized based on Xiao Yi's example a few days ago, and now its utilization efficiency of computing resources has also been improved.

In this way, as time passed, the results finally came out.

Looking at the final simulated results, Luo Mingya raised her eyebrows and began to analyze.

"Yes, by comparing the TDOS and PDOS of 2H/3R and 2H and 3R mixed states, it can be observed that the d orbital of W is the main allowed occupied and unoccupied state near the Fermi energy, which is consistent with the relevant DFT research based on the bulk crystal structure of MoS2."

"In addition, the DOS and band structure of 2H and 2H/3R polytypes also show that the minimum of the conduction band CB is located at the same point in the Brillouin zone, between the K point and the Γ point, and the maximum of the valence band VB of the 2H polytype occurs at the Γ point, while for the mixed 2H/3R polytype..."

"It seems that our work some time ago was not in vain."

She smiled with satisfaction.

"But the problem is..." At this time, she frowned slightly again: "In the case of spin-orbit coupling, we cannot correctly describe the energy loss spectrum, and the calculated value and experimental value seem to be quite different."

"This problem is a little difficult to deal with."

Xu Ming and the others looked at each other, even the invincible senior sister felt that it was difficult to deal with?

However, Xiao Yi said at this time: "Just double the number of required bands."

"After all, in order to correctly calculate the bulk plasmon peaks appearing in the energy loss region, more bands need to be merged into the joint state density calculation, which is consistent with the concept of plasmons."

Luo Mingya was stunned, "Double the number of bands? Plasmons..."

After a moment, her eyes lit up: "You're right!"

"Try it now!"

Then she began to adjust the parameters on the computer.

After the parameters were adjusted, it ran again, and the final result immediately made the calculated value and the experimental value not far apart!

"Oh my god, Xiao Shen, how did you see it?"

Xu Ming and Liu Chao next to him shouted.

Here it comes again!

The problem that their senior sister didn't associate with for a while, but Xiao Yi saw it right away!

If their big world is a god, then is Xiao Shen the god among gods?

Xiao Yi smiled and waved his hands, saying modestly: "Nothing, I just happened to read some books these two days, and I understand a little bit about this."

"In addition, I have two suggestions. Since the purpose of our topic involves the optoelectronic properties of two-dimensional materials, I think we can do doping simulations to calculate the effects of different doping elements and concentrations on the electronic structure of the material, so that we can predict which doping elements can optimize the optoelectronic properties of the material."

"This is the first suggestion. The second suggestion is to use molecular dynamics simulation to study the stability of materials at different temperatures and pressures and predict their thermodynamic properties. In addition, mechanical properties simulation can be performed to understand the elastic modulus and fracture toughness of the material."

"All of these can help us screen out the most promising material combinations."

After Xiao Yi's suggestions, Xu Ming and the others were not shouting, but shocked.

You have only studied for a few days?

How do you understand it so well?

"Xiao Shen, did you turn it on?"

"It's turned on if it's not turned off?"

Xiao Yi asked back.

I haven't turned it off since I turned it on. What makes you say I turned it on?

Chapter 142 I'll do it

Luo Mingya didn't know how many times Xiao Yi had shocked her.

But no matter what, his suggestions did make Luo Mingya think carefully.

Use doping simulation and molecular dynamics analysis?

And mechanical simulation...

His ideas can really help their research, but...

There are also certain problems in using these simulations. Luo Mingya said: "Your suggestions are all good, but there is a problem now. We have to think about how to conduct these simulations. After all, they take a certain amount of time, and to be honest, I haven't been studying computational materials science for long, only half a year, so I don't know much about the aspects you mentioned."

"There is someone in our research group who can provide help, but... it's basically impossible to get her to move."
