Hammer of Technology

Ning Wei glanced at Zhou Zhenghao impatiently, shook his head and said in a muffled voice, "It's your business if you want to help Ning Si pull people, so what's the point for me to say? Are you afraid that Meng Runze is the kind of person who has no idea? I told you a long time ago that how you go after graduation is your own business, and I won't care about you anymore."

"Hey, Director Ning, you're right. We're all your students, why don't you care? That's fine, I'll take the USB flash drive with Xiao Meng first." Zhou Zhenghao shrank his head brazenly, and then Turned around and walked out of Ningwei's office.

Although he acted cowardly, he was very proud of himself.

Because he knows that Ning Wei always speaks very tough words, but in fact he still loves these students very much.Since he made this request on his own initiative, Director Ning would definitely mention it to Meng Runze.

Of course, as to whether it will succeed or not, that's another matter.As Ning Wei said, everyone has their own plans for the future, especially these people, who not only have ideals, but also have strong execution ability.

But Zhou Zhenghao thinks that there is still great hope. They are both seniors, and when choosing a research direction, the two of them are very close, both of them are in the field of chip application. They often have some academic exchanges, and their personal relationship is naturally good. He Of course, it was very clear that Meng Runze had always admired Director Ning, so Director Ning's opinion must have had an impact on Meng Runze.

The most important thing is that the two know the basics. Zhou Zhenghao is very clear that Meng Runze's talent in research is actually higher than his, and he is more persistent in the pursuit of academics.In addition to doing research, he also has ambitions in operations and management.If Meng Runze could be brought to Ning Si, it would be perfect.

Not only is he more hopeful to achieve more achievements in the future, but also with the relationship between the two, if he wants to develop into management in the future, Meng Runze will also be his greatest support.

Although this kind of thing, Director Ning's words are quite useful.But Zhou Zhenghao knew that his own director, Ning, could give them detailed advice and guide them in the academic field.But apart from academic matters, there is a high probability that Director Ning will not make a special statement.

This can be seen from Director Ning's attitude towards things.

Most people in China know that Ning Wei is the youngest academician of the Chinese Academy of Sciences, but most people don't actually know how tough this academician is.

Basically, almost all national-level opening reports related to mathematics, semiconductor chips, and computer algorithms, including youth, general, key, major, outstanding youth, 973, 863, major special projects of the Ministry of Science and Technology, national science and technology support programs, and spark programs , Torch Program, etc., as long as Ning Wei is willing to participate in the review, his opinion can be said to be very important.

Let's put it this way, when a professor at Zhou Zhenghao's alma mater applied for a semiconductor-related national project, he approached him directly, hoping that he could talk to Director Ning and say something good about the project.

In the words of that professor, as long as Director Ning nods and helps to say good things about this kind of project, it can be said that the selection of this project is already half the battle.

The doctoral supervisor of his alma mater came to the capital to invite him to dinner, just so that he could help him speak in front of his tutor.

At that time, Zhou Zhenghao didn't know whether the other senior brothers had received similar invitations, but he just felt extremely embarrassed.

After coming back from the dinner, I talked about this with Meng Runze and realized that everyone had a similar experience. However, since Meng Runze studied at Yanbei University as an undergraduate, most of the time, he didn't need to be so polite and just refused.

I also know that although Director Ning will be nominated as an expert in the judging panel every year in the selection season of this kind of topic, Director Ning firmly refuses every time.

Probably the attitude is not to participate, but to ask, who loves so and so.It's useless for anyone to just keep their heads down and do their own things.

It is said that because of this matter, he even took a picture of the table in Director Tian's office...

However, the matter of patting the table is just hearsay, and no one will really ask if it is true.

But it can generally be seen that Ningwei's attitude towards power is not keen.So he didn't dare to think that Director Ning would speak up for him in this kind of thing, and he might even call him to scold him.

Zhou Zhenghao's guess was right. When he called Meng Runze to complete the copying procedures and returned to school with Director Ning in the car, Ning Wei really talked about the future with Meng Runze.

"Xiao Meng, what are your plans if you graduate successfully next year?"

Meng Runze said without hesitation: "Director Ning, are you in no hurry to graduate? I want to study with you for two more years."

This is absolutely true.

After all, following Ning Wei is very cool no matter how you look at it.Working for a tutor for free?nonexistent……

To put it bluntly, it is necessary to fight for a project with Director Ning.Ningwei is all tasks assigned by students according to their respective topic selections, and all work is rewarding.

In other words, enough money is given.

Ning Weishi has never asked about the state's various subsidies for graduate students and doctoral students.How much should be, how much is, hit the card on time.

The students received cash rewards from the school for posting top magazines, and they all belonged to the students.

During the period, Ning Wei applied for various laboratory expenses in the approval of the school's internal projects. Sometimes the funds for the subject projects have not yet come down.

In short, over the past three years, the students have earned a lot.On average, no less than those senior engineers of large Internet companies, at least buying a smaller house in the capital is enough.

The most important thing is the priority right to use the laboratory, and even help students find a highly cooperative project team when they encounter difficulties. After all, the face is there, and there is no shortage of money.

Not to mention highly targeted guidance...

In other words, as a student of Ningwei, you really only need to do your own research. If you can't get results, you can't find any reason other than self-criticism.

To be honest, the instructor is absolutely amazing in doing this.It's not an exaggeration to say that Meng Runze doesn't mind hanging around for another ten years.

It is a pity that, if you are sincere, in exchange for Ning Wei's scolding: "What are you thinking? You all hurry to graduate, how much time did I waste in order to take you? You all hurry to graduate, I am in a hurry to change the subject!"

------------

371 Don't Care About Those Details

"Change the subject?"

Ning Wei's words made the two students in the car look puzzled, except for the driver in the front row whose face remained unchanged.

Some sudden.

As a leader in China's mathematics, artificial intelligence, intelligent algorithms, and semiconductor fields, and even the undisputed No.1, why change the subject?

Is it because the previous research was too successful?

"Director Ning, which subject should you change to? Don't work on chips and artificial intelligence?" Zhou Zhenghao couldn't help asking.

"No, after I train you, I plan to do research on condensed matter, quantum, field theory, standard model and so on." Ning Wei said with a glance at Zhou Zhenghao.

"Director Ning, are you planning to enter physics?" Meng Runze was stunned and asked subconsciously.

"Well! In the past two years, I have been under pressure. Except for the class Ning, I have not recruited any more students because I want to spare some time to study first, but there are still too many things, and none of you can make people worry. And We can’t let go of the chips either. After our first batch of cpus are produced, this task will be entrusted to you in the future. There are children in Ningban who want to develop in this direction, and you brothers should be more proactive and help me Take them. Make time for me to come out."

Ning Wei seriously told his two favorite students about his plan.

"No, Director Ning, please don't do this. According to the previous plan, we should still be with you for two years." Meng Runze argued.

Ning Wei shook his head and said: "That's what I think. It will definitely be too late next year. If your big thesis is ready in March of the next year, we will have an internal defense. Don't worry, other examiners will be welcome in our direction. I said that you can graduate, but no one dares to say that you can’t. If you are really not ready in March next year, you will all go to Ningsi for an internship, and continue to prepare for the thesis while doing the practice. At the end of October next year, there will be a doctoral graduation assessment. So, you all should work hard."

Contradictions change, there are always people who are eager to graduate early, after all, the age pressure for PhD students is there.But here, under the most ideal teacher-student relationship for students, I really don't want to graduate.

"Okay, Director Ning. But isn't your subject a bit too big?" Although Meng Runze agreed, he still couldn't help asking.

After hearing this, Ning Wei smiled slightly, and explained patiently: "Is it big? Mathematics and physics are inseparable. Especially for your future research on chips, it's okay to say now that the three-dimensional silicon body will break through in the future." When it comes to the 1nm process, don’t you have to deal with physics? Let’s not talk about the complexity, just say that you have followed me to do chip projects in the past two years, which should be very familiar with the working logic of the transistors inside the cpu. There are more transistors, and the moving distance of electrons is correspondingly shortened. The internal movement of electrons spontaneously through the silicon backplane of the transistor channel from negative to positive leads to leakage."

"These leaked currents will cause additional power consumption. With the upgrade of the cpu process, this problem will become more and more serious. Our bottom plate and high plate are only more than ten atoms thick. If there is too much leakage, the insulating layer will be damaged. Thinner, how do you plan to solve these problems in the future? Intel uses high dielectric film and metal gate integrated circuits to solve this problem, and IBM is burying a layer of strong dielectric film on the source and drain to solve the leakage problem, but these are all technology in a two-dimensional environment."

"Be aware that under the three-dimensional channel, the chip will be more sensitive to power consumption. Especially the internal heat generation of a single tube is doubled. You should remember the test done before. Adding more heat dissipation leads will reduce the proportion of the number of transistors passing through the inner wall. Right? This is because our current technology is not too advanced. I have done calculations. When upgrading to the 14nm manufacturing process in the future, the current heat dissipation structure will not be able to adapt, and new technologies are needed to dissipate heat.”

"This requires new materials, new processes, and new technical means to solve these problems, and you need to use broader thinking to solve a series of problems. At that time, many problems are not purely mathematical problems, but more physical problems. .That’s right? So, a true scientist must not only have the depth of knowledge, but also the breadth, and you must always remember this.”

"Although you all know that I have been very low-key these years, some people in the academic world still think that I am a signboard, and some people even brought up the term Ning's scholar. Don't laugh, these are the last time your Dean Yao had dinner. I told it to me when I was there. I was a little uncomfortable listening to it before, but I have figured it out these days. One point, since you have already been labeled as schoolboys, at least you must be worthy of this title in terms of knowledge."

"Finally, let me tell you that what you are doing now is very meaningful and extraordinary regardless of the market reaction in the future. The significance lies in the fact that in the future, we will be able to survive on our knees or change careers and leave. The choice to stand up in the industry. I don’t care what others do, but you are my students and you must always remember that since we are called “scholars” by others, we must have the self-consciousness and pride of “students”, no matter which one we look at in the future In the industry, not only do you have to stand up to make money, but you also have to straighten your chest, understand?"

Probably because it was on the bus back to school, Ning Wei was not afraid of wasting time, and instilled some different thoughts into the two lovers, and rarely talked at length about his own mental journey over the years.

Of course there are reservations.

For example, the pursuit of physics knowledge has little to do with the CPU industry. It is entirely because the inequality that has been confusing him has been circling in his mind more and more frequently recently.If you have to make an analogy, it is probably the purest desire for knowledge, which makes him want to spare more time to do these things.

But for Ning Wei's students, this is also easy to understand.

Although Ning Wei is a mentor, he is not much older than them in terms of age, that is, one or two years old.Ning Wei is only 28 years old this year. It is normal for him to study for a Ph.D. at this age.Calculated according to the normal study age, if you graduate from university at the age of 22, if everything goes well in graduate school, you will have to be 25 to get a master's degree. is a low probability event.

But if you choose to continue to study for a Ph.D., the situation will have to be reversed. Basically, only a few lucky people will graduate on time, and the majority will be delayed.In other words, a normal Ph.D. student is only 28 years old and has only been a Ph.D. student for three years, and he is still in the stage of struggling with a dissertation.And Ning Wei is 28 years old and has been a doctoral supervisor for more than three years. It is not a big deal to change direction at this time.

After all, it took only two years for Ning to complete the master-doctoral studies, and the master's degree was basically skipped directly.For a student who has solved two world-wide mathematical problems at the undergraduate level, there is definitely no embarrassment in the matter of giving proof.

So Director Ning put higher demands on them, and it seems that there is nothing wrong with thinking about it carefully, and he can't think of any reason to object.

"Director Ning...we will definitely work hard."

"Well, that's good, don't be idle during the filming period after returning to school, go and have a good communication with a few senior brothers, such as Xiao Li, Xiao Zhuo, oh, yes, especially with Zhang Ding Xi Duo communicated, his project has made great progress, I watched the latest laboratory report he sent yesterday, and the attached video image, it is really good. Pick a time to visit their laboratory, for the future It will help when you design the CPU."

"Eh? Brother Zhang also made a breakthrough?"

"Haha, you'll find out when you go and have a look." Ning Wei smiled easily. After these people were brought out, he could indeed relax a lot.

……

"Brother Zhang, Director Ning specifically explained that we want to learn from you this time, saying that your research project has made a breakthrough. No, the first thing after Lao Meng and I came back is to treat you to dinner. You can't hide anything from us." At the dinner table, Zhou Zhenghao said to Zhang Dingxi with a smile on his face.

However, Zhang Dingxi obviously didn't appreciate it very much. He glared at Zhou Zhenghao and scolded directly: "Go away, don't do this with me. You two are the most thieves among our group, and the projects you choose can be confused with Director Ning." It is indeed better than us to be told by Ning Dao every day, but if you invite me to dinner and show off, isn't it too much?"

"What's going on? Brother Zhang, if you want to say that, we have to talk about it. Yes, we worked with Director Ning as the CPU, and it is true that we spent longer together. But brother, what does your laboratory say? In order to let you have For a good research environment, Director Ning directly bought hundreds of millions of dollars to set up a laboratory. Your side has high requirements for materials. Director Ning can't wait to let the Institute of New Materials cooperate with you in experiments, help you choose materials, and give them a good research environment. We started with tens of millions of project funds. We haven’t said that Director Ning is biased, and you still have the nerve to say that we are showing off?” Seeing that he was being teased for speaking well, Zhou Zhenghao immediately scolded him.

Although Zhang Dingxi is the oldest among the ten people, everyone called Zhang Ge to show respect.But to be honest, everyone entered school in the same year after all, and their ages are not much different, and they are all arrogant masters, so there is nothing to scruple about arguing.

Zhang Dingxi puffed up his chest, rolled his eyes, and said in a muffled voice: "Hey, why don't you say that you can still go to the research center over there? Don't show off your power in front of me, I'm getting angry these two days! You guys What are you going to see in the lab? Look at my joke! Director Ning provided me with such good resources, and I made the project like this, I want to die!"

Meng Runze, who had been sitting by the side without saying a word, understood what the two were arguing about, and calmly said, "Brother Zhang, isn't it? Mr. Ning was on his way back just now, and he seriously praised you for doing a good job now." Come on. The original words are that your subject has made great progress, and you are doing really well, so we must visit your laboratory and learn about your research progress."

This sentence finally made Zhang Dingxi stop acting like a hedgehog, and asked suspiciously: "Dr. Ning really said that?"

"Nonsense! Otherwise, why do you think that Runze and I invited you to dinner the first time we came to school?" Zhou Zhenghao said angrily.

"I heard you say that just now, and I thought you two were going to show off in front of me! Use my failure to show that your recent cpu project can be successfully taped!" Zhang Dingxi said immediately.

"Are we that bored? No, Brother Zhang, you have high demands on yourself now! Director Ning thinks that you are making good progress, but you still feel dissatisfied? Is this because you want to eat a big fat man all at once?"

"Forget it, I'm too lazy to tell you. In this way, let's stop drinking and go to the laboratory in the afternoon, and I will show you. When the various materials were made separately before, they were all perfect. I'm almost dying of worry. Director Ning probably wants to encourage me through your mouths?"

"Okay, okay, then let's eat something casually, first go to the laboratory to have a look, and we will invite Brother Zhang to a big hotel to eat in the evening!"

"If you can give me some advice and improve the product, I don't want you to invite me. I invite you to the state banquet!"

……

"Okay, Lao Zhang, are you still not satisfied with the effect of this finished product? You still want to make something perfect in one go? Our first tape-out failed!"

"go away!"

"Let's be serious, Brother Zhang, I looked at it. Your gesture recognition is mainly based on the optical flow information method and the skeleton model. You can consider the support vector machine to follow the machine decision forest. Especially for the recognition algorithm, there should be tracking Weighted options, especially in complex light backgrounds, filter out the adverse effects of non-targets on tracking targets."

"Well, this can be considered. My initial idea is to install two infrared-compatible sensing modules at the two t-point positions. After all, if you just blindly join the neural network and extract target features to train the classifier, The robustness is high, and the effect should be good, but the requirements for computing resources are too high, especially the requirements for GPUs are too high."

"I know why Director Ning asked us to take a look at your research. Brother Zhang, don't be afraid, this piece will be supplemented by our chip. This piece can be handed over to a special module for complexity, especially in [-]D mode."

"What about trouble? I was brought by the cluster!"

"Who is making trouble with you! What's wrong with the cluster? You have to consider daily applications and supporting software support. In the early stage, if you really made 3D high-resolution, no matter what GPU you use, it will still be the same! I'm right. And have you never thought that it is because you have been thinking about the clarity of 3D display that the positioning is not accurate during gesture recognition? You have to eat one bite at a time, give up 3D high resolution, and make the spatial positioning accurate first. gone."

"I also think this is the case. If you really want to have a clear requirement for the three-dimensional composition, you can use a special method to achieve it. Use an algorithm to achieve partial filling, and let the cpu smart board take part of it. We must maximize our advantages to the extreme! Anyway, now we don’t want to use your 3D display to compose images inside the chip, and EDA doesn’t support it now! But then again, when the technology matures and the software supports it, this display technology can really save a lot Things. The most important thing is that this can reduce the unit price! Consider the price-performance ratio, Brother Zhang!"

"I also think, Brother Zhang, you have to work hard. Listen to us, the first-generation products don't need to be too mature. You can make a display that surpasses the times. It's useless without software support. Think about it. How touching is the image quality of the VR that just came out? Is there a market for it? Not to mention that you can also do naked-eye VR. Is it better to bring one of those things?"

"Well, let's teach Junior Sister Jingwen in the future, let the Hongmeng system come up with a few players and games that are suitable for this kind of 3D display, and match it with our cpu, which is a proper domestic one. Light, brother Zhang!"

"Nimma, you are enough, is it really good to lower the final parameter requirements of the product?"

"The world's first similar product, let alone the national standard, there is no standard in the world. Of course, this standard can be set by yourself. That's what Director Ning said. Why are you so demanding? The first batch of products made a miracle. Come on, do you still have room for improvement in the future? Director Ning did not say that he would go to 7nm when he was working on a CPU, did he? We are still spinning around at 60nm, so you just want to show off?"

"I……"

"Don't talk about Brother Zhang, I also think what Lao Zhou said is right. Lower the standard, first produce a finished product, and then gradually upgrade the standard. I suggest that you can call Xiao Chen later, so that Ningshe can respond to the new display. model, make an extra piece of software with better adaptability. Brother Zhang, you can’t always rely on Ning Dao to give you money for projects, can you? First see if there is a market, explore the way, and be accepted by the market. Sometimes you don’t want to upgrade, and there are people lining up to spend money begging you to upgrade.”

Zhang Dingxi, who has always adhered to the concept of perfectionism, was finally overwhelmed by Meng Runze's words.

It is true that Director Ning is rich, but he has been investing in this project. Every time he runs out of money, he can only bite the bullet and ask for money. Every time the money is approved, the reply is very immediate.

Although Ning Wei has never talked to Zhang Dingxi about burning money, Zhang Dingxi is really embarrassed. Now every year when Ning Wei treats him to dinner, he is embarrassed to sit next to his mentor...

For people with normal three views, the mentor is too good, isn't it a different kind of pressure?

"Okay, don't talk about it, just do it! If this is the case, you can remove a few light sources and add sensors, so that the layout will be easier to design, the yield rate will be higher in production, and the finished product will be reduced. Around 30.00%."

"That's right. And the same product should be divided into low-end and high-end. In the future, we can develop the high-end route of resolution, scientific research level, work level, and consumer level can be made separately. Although we only do technology, but Also add some market thinking. Xiao Meng, is that what Director Ning said?"

"Old Zhou, I'm sure Director Ning has never said that in front of me!"

"Ahem...Brother Zhang, don't pay attention to these details. I may have misremembered. Xiao Meng was not there when Director Ning said this. Anyway, let me tell you, this decision must be correct!"

372 I want to express my opinion

"Hey, Ke Ke, Dad brought you toys, but you have to tell Dad first, do you miss Dad?"

"I think... I really want to, I really want to..."

"What do you miss dad?"

"What gift do you think Dad will bring me?"

……

As soon as he returned to school, Ning Wei went straight home, and then fell in love with his dear little girl.

Xiao Ning at home has grandpa and grandma watching over him. Jiang finally chose to work in the logistics department of Yanbei University. The school thoughtfully arranged for Jiang a logistics post with little money but fewer tasks. As long as he completes the tasks every day, he can I can go home with my kids.
