"I would rather think that this child... is still thinking clearly!"

"yes."

"By the way, why did the media over there suddenly make such an announcement? Are they trying to flatter me?"

"It's not even a big deal. The main thing is that Ning Wei scares me. It's probably to show goodwill."

“Unleash kindness?”

"Yes, the previous incident made some media more passive. Several large companies fell into a relatively passive situation in terms of products due to the sudden exposure of vulnerability issues. This also made many people dissatisfied. CNN fired the online media within a week Two senior managers at the director level of the department responded to Facebook and Twitter’s joint efforts to block the official accounts of state media. As for other media, they were probably also notified.”

"Huh... It seems that the future is already dominated by young people. By the way, I heard that he is currently researching desktop-level CPU products?"

"Yes, Huawei has specially set up Ningsi Laboratory to cooperate. In addition, China Micro Precision Holdings Group, through its subsidiary Tianbang Technology, cooperated with Huawei's 2012 Laboratory, each investing 50% to establish Silicon Times Technology Co., Ltd. The company aims to develop master control chips for smart cars; Huaqiang Software, Galaxy Baize, and Huawei Euler have joined forces with the Intelligent Frontier Central Laboratory to create a domestic full-coverage operating system ecosystem. In addition..."

"Stop, there is no need to report on these commercial market cooperation for the time being. We will wait until they have negotiated and actually achieved results. All departments will do a good job in guiding and provide sufficient support in accordance with the proposed policies. As for the media, It’s better to just sit back and rest, as a saying goes well, we don’t need others to affirm the achievements of our scientific and technological workers, the most important thing is to provide workers on the front line of scientific research a quiet environment to do research.”

"OK!"

"By the way, the little guy is going to be elected as an academician, right? What does the committee mean?"

"Most of them agree, and those who have reservations are not allowed to mention it. After all, Ning Wei's achievements are there, and the big names in the academic world who have not spoken out for a long time have spoken out in private to support him. .”

"Well, I'm sorry to mention it! You can help me talk to everyone at the next meeting. Don't be stubborn. Age is not the only way to do scientific research. The younger generation can produce results, and there is a channel for exceptional promotion. A good thing. Not only Ning Wei, but also other young people must dare to promote if they can make the same results. As long as young people have made outstanding contributions in China's medium and long-term science and technology development plan, they still have to shoulder the burden. "

"yes!"

"Since there is no problem with the evaluation of academicians this year, let's go one step further. As an academic committee member, at the level of Xiao Ning, no one should be able to make some scientific research suggestions and provide some academic consultation and evaluation in the areas he is good at. Opinions, right? Moreover, the committee has younger blood, which can also have a positive significance for the reform and development of the scientific research system. We need to listen more to the voices of young scientific researchers and understand their ideas and difficulties."

"Okay, I will communicate your suggestions to the academic committee as soon as possible."

"Well, that's it for now, next topic."

…

"...This kind of design feels like it will make the instruction set bloated. I think we still have to solve this problem through other means. For example, Apple M1 uses ARM reduced instruction set. Its benefits are obvious, such as high efficiency and good flexibility. Developers can deploy and implement highly customized functions more flexibly, and the execution efficiency of the software and the low power consumption of the CPU can be maximized."

"But everyone should note that the disadvantage of the simplified instruction set is that after it is streamlined, it is difficult to achieve universal applicability. A high degree of customization will greatly increase the cost of adaptability for future market development. Unless everyone has the energy to Design different CPUs for all devices to meet China's differentiated market needs. So the idea of ​​this instruction set is to take the middle value between X86 and ARM."

“On the one hand, we must pursue high performance and high versatility, and must be open enough to be accepted by the market; on the other hand, although we can appropriately give up the high-customization features of the simplified instruction set, we must retain its single-core execution efficiency, and at the same time We still have to make a choice between the two. I dare not say that this instruction set is the most perfect, but I feel that under the current conditions, we have done our best to take into account both.”

"I named this instruction set Njsy instruction set. I hope everyone can read the complete code of these instruction sets as soon as possible. Next, I will put forward some personal ideas on the chip architecture and design. First of all, everyone is considering the CPU design plan. At this time, we must fully consider the technical characteristics of three-dimensional silicon silicon tubes. At the three-dimensional level, we can carry out SOC layout more elegantly and maximize the three-dimensional advantages."

"My suggestion is that in addition to the first, second, and third-level cache, we should design a unified memory bank so that some key information does not need to be serially communicated through the motherboard connection, and data exchange is completed directly in the unified memory bank, once To solve the problem of delay and limited access bandwidth; take advantage of three-dimensional advantages to stack different cores and caches on different three-dimensional levels to ensure exchanges between cores, cores and caches, and cores and memory at one time speed, while GPU cores and CPU cores share memory."

"Secondly, integrate neural network computing and bionic chips into the chip, and give it a dedicated computing channel and level. I have already reflected this in the design of the instruction set..."

…

Ning Wei was facing the screen and explaining his ideas and requirements to Ning Si's core combat team bit by bit.

Throughout October and November, after working day and night, my own instruction set was finally released.

Although it has not been tested in practice, the entire instruction set system has been subjected to various digital simulations for several days in March, which proves the scientific nature of this instruction set.

Of course, for Ningsi Lab and its partners, everyone is probably still feeling confused...

Mainly it's too fast.

For these core personnel, of course everyone knows that Ningwei only spoke in mid-September under the influence of various factors to support the research of independent instruction sets, rather than building instruction sets for new chips by purchasing or cooperating with open source platforms.

After making the decision, it is said that Ningwei started designing the instruction set, and Huawei began to set up the Ningsi laboratory. As of the end of November, in two and a half months, the Ningsi laboratory has only been completed for about a month, and the core Many members of the team come from within the laboratory for support.

If you go through social recruitment and poach people, this time is obviously not enough, and school recruitment is even more impossible. Without several years of work experience, it is impossible to be directly assigned to such a department that directly produces results.

Being able to complete the formation of the core team of Ningsi Lab in more than a month is thanks to a lot of help from partners.

However, everyone had just spent a month getting along, and when everyone began to prepare for a big fight with some of the instruction set ideas that Ning Wei had provided before, this meeting made everyone's eyes widen.

This person actually completed the instruction set single-handedly?

No, it can’t be said that it is done alone. After all, there is still the full support of the March Intelligent Platform. But really speaking, the authority given to Ningsi by the March Intelligent Platform is also very high. At least compared to other projects in the laboratory, Ningsi Laboratory The submitted calculation requests and numerical simulation tasks can often be prioritized. If the calculation requests and numerical simulation tasks are repetitive, even if they are rejected by the system, the recent calculation results will be provided simultaneously as a reference.

So everyone is very confident.

I have already shouted the slogan that I must assist Professor Ning in half a year to complete the architecture and compiler of the new instruction set.

Really, this is a slogan used internally to promote chicken blood!

Of course, the instruction set here is for the design of a new three-dimensional silicon silicon tube CPU, but unlike those glamorous products that have mostly been eliminated by the market, the entire instruction set and compiler must demonstrate excellent performance and have the same The difference between the popular instruction sets on the market is that the underlying design is always better than the instruction sets that have been tested by the market in some aspects, so half a year is not a particularly exaggerated time.

Similarly, everyone also needs this time to adapt to the rhythm, and at the same time, we have to wait for the complete tool chain from minimalist EDA...

However, I never expected that while everyone was shouting slogans loudly, Ning Wei had already completed the instruction set independently. Half a year? It doesn't exist. It only took about two months and nine days to complete the calculation...

So the auxiliary work may turn into learning and understanding.

At this time, everyone probably experienced the feeling of when Yu Xingwei assisted Ning Wei in designing the turbulence algorithm.

When he was gearing up to show off his skills, he finished everything first.

Even at this stage, the minimalist EDA design tool for large three-dimensional silicon through-silicon tubes is still under intense production, and the current version of the tool chain is not complete enough.

This probably leaves enough study time for everyone...

For the researchers at Ningsi Laboratory, the mood is probably extremely complicated.

Of course, it will definitely be extremely pleasant for Huawei and its partners.

The faster the R\u0026D speed, the less money is invested. If nothing else, there are more than 700 front-line R\u0026D personnel in Ningsi Laboratory, plus nearly 1,000 logistics, administrative, financial and other personnel. .

Purchasing various insurances and employee benefits requires an average monthly expenditure of 40K per person, which amounts to 40 million in expenses per month. Completing the set tasks half a year ahead of schedule means that 240 million in R\u0026D costs can be saved in terms of human resources alone.

From this point we can see the value of Ningwei.

Of course, from Ning Wei's perspective, there was nothing he could do.

He could ignore the entire CPU production and design chain behind the three-dimensional silicon silicon tube, but he was fully responsible for the initial chip instruction set and architecture design. And in the short term, this matter really cannot be completely handed over to others.

But he is still very busy in both the short and medium term.

First of all, next September he will officially take charge of his direct Ph.D. students, which first requires him to spare some of his energy.

Secondly, in September, the child in Ning's class will be a sophomore. Although he does not need to directly take over as a substitute teacher, he has to start paying attention to the children's results. After all, in the sophomore stage, there are competitions to participate in. Yanbei University targets outstanding students. His scientific research training plan has also officially begun, and he has to find a way to give more guidance to his proud disciples...

In addition, he must also participate in some activities at the end of the year.

In mid-November, the list of additional academicians, which has been brewing for half a year, has been officially announced. Ning Wei is among them, selected as the youngest academician of mathematics in China. In Tian Yanzhen’s words, with the title of academician above his head, he will attend some meetings in the future. It definitely can’t be pushed away.

At the same time, Ning Wei was also directly selected as a researcher at the Institute of Mathematics and Systems Science under the Chinese Academy of Sciences. The purpose of the institute is to solve major mathematical problems in China's strategic needs, so he couldn't refuse. Although there are no tasks assigned to him yet, everyone knows that Ning Wei is currently working on an instruction set project, and there will definitely be more in the future.

In addition, Ning Wei also received a notice. The Academic Committee of the Chinese Academy of Sciences has begun discussions to recruit Ning Wei as a formal member...

Lu Changbin was probably the happiest when he heard the news.

After all, in the future, whether you want to get support for various project selections or whether you want to get national key laboratories, outstanding youths, Yangtze River Scholars, various scientific research awards, etc., you will inevitably have to deal with the experts of the academic committee.

Ning Wei became a member of the academic committee, coupled with his own influence and achievements, and if combined with Tian Yanzhen's influence, basically no one would openly oppose his opinions in the fields he is good at.

But in fact, Ning Wei is not very interested in reviewing other people's projects. Because of the principle of appropriate rights and responsibilities, if he wants to review other people's projects, he will have to spend more time and energy to understand those projects, and then give his own evaluation. This requires some allocation of energy.

So Ning Wei originally wanted to refuse, but Lao Tian had a deep talk with Ning Wei and hinted that Ning Wei could play a great role in this position. For example, it saves a lot of money that may be wasted. Because he is still young and independent in scientific research, he does not need to give anyone face, which allows him to give pertinent opinions to a large extent.

Especially since his joining the committee this time has been strongly recommended by many big guys who silently support him behind the scenes, Ning Wei should seize this opportunity.

Director Tian came to persuade him personally, which meant that he could not refuse.

In addition, next month the March Award will be announced for the first time, and he wants to stand up; at the end of the year, many units have sent invitations to him for cooperation, hoping that he can make an appearance. The most important thing is that he originally He plans to have a basic understanding of various theories at the physics level this year and determine the best entry point for research. However, the progress is still very slow. Let alone choosing the best entry point, the fragmented time is not even enough for him to complete the research. Let’s briefly review the entire physical system.

This is very heart-wrenching.

It would be hard for him to wait until school starts next September and still hide in the laboratory to study physics knowledge. It would not sound good if word got out.

Think about it, with a group of direct Ph.D. students who are sincerely learning mathematics from him, and with a high salary, they still worry about choosing an entry point for physics research every day, which is somewhat embarrassing.

But if we can figure out the entry point for research before then, and preferably produce some results, we will feel much more confident.

So Ning Wei is also very sad. In order to get the instruction set and compiler, he works almost day and night. Both Liu Wei and Jiang can testify to this, especially Liu Wei. After all, it is not convenient for Jiang to prove these things. thing……

In addition, Ning Wei also plans to complete the wedding ceremony with classmate Jiang in June next year. Although classmate Jiang means to keep everything simple, Ning Wei still feels that he should give classmate Jiang a decent wedding. After all, he has no plans to get married. Married twice. According to the ideas of Ning's father and Ning's mother, this wedding banquet will have to be held three times. The hometowns of Ning Wei and Jiang are definitely indispensable, but Ning Wei's main activities are now in the capital, so it is not easy to omit them here.

Things pile up one after another, which indeed makes time seem particularly precious.

Just like now, the work on the instruction set has finally been completed temporarily. The next stage of chip design work has not officially begun, and a bunch of things have come to the door.

"Really, Brother Liu, it would be great if one minute could be turned into 120 seconds in the past two years. The time is too long. By the way, can you help me postpone the meeting at the Academy of Sciences next week?"

"This summary meeting should be postponed, but I will definitely have to attend the work planning meeting in January next year and the congress in May."

"Let's talk about next year. The list of the March Smart Awards will be announced next month. My idea is that the awards ceremony will also be scheduled for March next year."

"Professor Ning, these questions are easy to answer. You'd better decide where to spend the New Year this year?"

"Just stay in the capital. I'm a bit busy this year. I'll waste time when I go back. I think this year will be over."

"Well, that's okay, I can make arrangements later."

…

Now, in addition to Liu Wei's duties as bodyguard and driver, Liu Wei is becoming more and more like a secretary.

After all, this area is relatively easy to use. Liu Wei can help Ning Wei to reject meetings that he does not want to attend more efficiently. If Liu Wei is not able to reject meetings efficiently, it is probably a meeting that Ning Wei should attend. .

From Liu Wei's attitude, he can quickly select and plan the itinerary. Naturally, he should make good use of it. In addition, if he wants to travel far away, Liu Wei will be required to arrange the transportation to connect the itinerary, so this is not too much.

As for what Ning Wei usually studies, Liu Wei doesn't care.

"Take it harder this year. Let's finish everything and wait until next year's New Year to relax. By the way, according to your customs, should you go to the man's house or the woman's house in the first year of marriage?"

"Professor Ning, there are a lot of things to do at the end of every year. I estimate that your duties will increase next year and you will only be busier. To be honest, I think you should forget about customs and bring both families directly to the capital next year to celebrate the New Year. , is the right thing to do.”

After hearing this, Ning Wei subconsciously looked up at Liu Wei. Suddenly, he felt that the computer in front of him no longer smelled good...
