The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 156: A share of the pie, a burst of inspiration (please subscribe)

On the evening of January 15, 1980, in the teachers' dormitory building of Harbin Institute of Technology, Wang Duoyu was reading at home, and Zhu Ling was helping to make tea.

After a meeting a few days ago, Diao Pai Electric Bicycle Company quickly started battery production.

However, Wang Duoyu does not need to deal with these matters. Harbin Institute of Technology has relevant management talents who will assist in solving this problem.

The sales of lead-acid batteries were led by Associate Professor Shang Zhongmin, who traveled around the country with his team to sell the products door-to-door.

One thing that is beyond doubt is that the product quality of lead-acid batteries is very good and its application range is very wide.

Among similar products today, Diao brand lead-acid batteries are second to none in terms of product quality, safety, and stability.

As a university, Harbin Institute of Technology has no shortage of talents. In addition, under the current background of economic development, the thinking of many people has begun to change.

Everything must be based on money!

Wang Duoyu just told Professor Shang Zhongmin and others about the many advantages of lead-acid batteries at the meeting, which actually explained its selling points.

With the abilities of Shang Zhongmin and his colleagues, I believe they can bring back a lot of orders for Diao Pai Electric Bicycle Company.

After this incident, Wang Duoyu talked with Xin Zhouping, Zhang Jichuan, Fan Baojiang and others about the progress of technological innovation in the three major sectors: motors, batteries, and electronic control systems.

If Diao Pai electric bicycles want to become a hit, they must come up with a flagship product that will make consumers want to buy it.

Secondly, costs must be reduced while ensuring that product quality does not decline. Otherwise, the price will be too high and it will be useless.

On the other hand, electric bicycles are not just for home use. Some people want to seek excitement, so Diao Pai Electric Bicycles can also produce some relatively expensive bicycles.

Such a bicycle must be fast enough, the battery must be stable enough, the electronic control system must be flexible enough, and the electric bicycle manufactured must be safe enough.

In addition, related technologies can also be further developed in the three major sectors of motors, batteries and electronic control systems.

For example, for batteries, we can also develop lithium-ion batteries, nickel-metal hydride batteries, etc.

Therefore, the research and development of electric bicycles is endless.

At present, Diao Pai electric bicycles have sufficient scientific research funds to support the scientific research work of Zhang Jichuan and others, so there is no need to worry about this at all.

In short, if you spend as much money as you can, you will definitely be able to produce more technologies and better products.

After Wang Duoyu finished drawing the pie in the sky, he escaped.

The next day, Zhu Ling came to Harbin Institute of Technology from Beijing to visit Wang Duoyu. She said she came to see him, but in fact she was avoiding her parents' Tang Monk chanting.

Wang Duoyu is happy to see this happen.

"More fish, more tea."

Zhu Ling prepared tea and poured a cup for Wang Duoyu.

When the latter was about to pick it up, there was a loud bang outside. It was the explosion that scared them both.

The teacup in Zhu Ling's hand fell directly to the ground, and the boiling hot tea splashed everywhere. Wang Duoyu was quick-witted and immediately pulled her aside to help her check if she was burned.

After confirming that both of them were fine, Zhu Ling still looked out the door with lingering fear, her pretty face pale.
"Could something have happened?"

Wang Duoyu said with a gloomy expression:

"I'm not sure. You wait at home. I'll go out and take a look."

Soon, he came outside and saw many teachers coming out of the corridor. Because it was the weekend, many teachers stayed in the dormitory building.

After confirming that the accident was not in this building but outside, Wang Duoyu had to go home and wait for news.

At this time, there would naturally be relevant school leaders to deal with the matter. He was just a mathematics professor, and he couldn't help with something like an explosion, so he didn't go and join in the fun and cause trouble.

Not long after, Wang Duoyu and the others found out the details.

It turned out that a new employee in the new factory next door used a gas tank to cook, and the gas tank exploded due to improper use, resulting in three people being seriously injured and four people being slightly injured.

It is not yet known whether the three seriously injured people can survive, as they have been sent to the hospital for emergency treatment.

"A gas tank exploded?"

After Wang Duoyu learned about this, he looked strange. How could such a thing actually happen?

In the 1960s and 1970s, gas cylinders and gas tanks began to be promoted across the country, but the penetration rate was very low.

In cities like Bingcheng, the majority of households still burn coal or firewood, while in big cities like Beijing, as early as 1979, there were already 670,000 households using gas cylinders.

As a university, it is normal for Harbin Institute of Technology to use gas cylinders.

Inside the factory, the project had just started and the management was rather chaotic. In addition, firewood and coal were not so convenient to obtain. Moreover, it was already January, so it was not so easy to temporarily transfer so much coal or firewood.

The Diao Pai electric bicycle battery project recruited more than 200 people in a short period of time. After training, these people will produce batteries.

As a result, the problem occurred before the battery production even started.

That evening, Liu Deben convened a meeting of relevant persons in charge overnight, and some school leaders participated in this safety production meeting.

The next day, Wang Duoyu came to the teaching building of the Department of Computational Mathematics and worked on his plan.

He did not go to see the gas tank explosion site yesterday evening, nor did he ask Xin Zhouping and others about the situation because they must be very busy now.

In the middle of the morning, Wang Duoyu called Lin Dehong.

"Boss, I have a plan to make money. Would you like to listen to it?"

"Of course I have to. You're at Harbin Institute of Technology right now, right? Okay, wait for me for forty-five minutes, I'll be there soon!"

Lin Dehong was very happy. He didn't expect Wang Duoyu to come up with a solution so quickly, so he couldn't wait to run to Harbin Institute of Technology to find Wang Duoyu.

He said it would take forty-five minutes, but he showed up downstairs of the teaching building in half an hour.

In the office, when Lin Dehong saw Wang Duoyu, he didn't even say hello and directly asked what the plan was.
Upon hearing this, Wang Duoyu handed the pages of paper next to him to the other party.

"Gas cannonballs?"

After reading it, Lin Dehong suddenly said depressedly:
"Comrade Wang Duoyu, what kind of plan is this? What's the point? No matter how good the gas tank shells are, they need people to use them. If we make them, who will we sell them to?"

Hearing this, Wang Duoyu said with a smile:
"Have you forgotten the battlefield in the Middle East? There's an oil crisis going on there right now."

At the end of 1978, drastic changes took place in the world's second largest oil exporter. The moderate King Pahlavi stepped down, and then the second oil crisis broke out.

Because at that time, there was already a war in the Middle East, and it was a very brutal war.

Throughout 1979, global oil production plummeted from 5.8 million barrels per day to a few hundred thousand barrels, while oil prices soared from US$13 per barrel to US$35 today.

Not to mention the rising oil prices, let’s just talk about the current chaotic situation in the Middle East. Both the United States and the Polar Bear Empire have made a lot of money.

Isn't it normal for us to participate and get a piece of the pie?

After Wang Duoyu finished speaking, Lin Dehong frowned and said hesitantly:

"We have no legitimate reason to do something like this, and if it were discovered, it would easily cause huge trouble. I'm afraid the higher-ups wouldn't agree at all."

Wang Duoyu laughed when he heard this:

"If you're scared, then don't do anything. Even if you go home to farm, you'll still encounter natural disasters and man-made disasters. What do you think, leader?"

Lin Dehong immediately glared at the other person and said angrily:

"Do I need you to lecture me on these matters? I want to ask you for a solution, not to cause trouble for me. Do you understand?"

So infuriating!

However, Wang Duoyu rolled his eyes and gave the other person a blank look:
"Leader, don't we have so many confidentiality regulations? Do you think they're just for show? When we produce these gas cylinder shells, won't you have them produced according to foreign standards? There are so many strategies like the Thirty-Six Stratagems and Sun Tzu's Art of War. Why not now or when?"

"And with so many talented people in your unit, I just can't believe you can't secretly transport these gas canisters and shells to the Middle East battlefield, away from everyone's sight."

"The Americans can even graze cattle across the ocean, but we can't even do this?"

If something could be completed smoothly in the original time and space, how could it be impossible to complete it in this time and space?
Wang Duoyu discovered that Lin Dehong was just too lazy to think about it, and the latter wished that Wang Duoyu could make the plan perfect.

In this way, after Lin Dehong gets the plan, he can execute it directly.

It’s a nice thought, but Wang Duoyu sneered at it.

He is mainly responsible for drafting the plan, how to implement it, what problems may be encountered during the implementation process, and how to solve these problems. That is not something he can interfere with.

We can't let him, a man who only knows how to write, go to the Middle East to do business with others, right?
joke!

"Oh, right, I remember you told me before that the troops were getting a new set of equipment. In the 1950s and 1960s, they switched to the Type 56 family barrel. All those previous International brand firearms were left to molder in the warehouse. Now they've updated their equipment with some improved Type 78 automatic rifles, and they've also laid off some staff."

"Can these guns be shipped to the Middle East and sold there first? If you find it difficult to ship them there, you can always bid for them from abroad. I believe many people are willing to take this risk."

When Lin Dehong heard Wang Duoyu's suggestion, his eyes suddenly lit up.

This is excellent advice!
Not to mention other units, just take Lin Dehong's current unit as an example. The warehouse is filled with a lot of old International brand firearms such as the Type 38 rifle. These things are antiques left over from the Anti-Japanese War, the War of Liberation, the Peninsular War, and the Plateau War.

They are literally just piled up in the warehouse and getting moldy, and no one wants them.

The leaders above are very troubled. What should they do with these guns? After thinking about it for so many years, they still haven't solved this problem.

To be honest, Wang Duoyu’s suggestion is really perfect.

"Come on, Duoyu, come with me. I'll take you to meet my boss. I believe your plan will definitely make him very happy."

Lin Dehong stood up and was about to take Wang Duoyu away, but the latter helplessly shook off his hand.

"Boss, I've already given you the plan. You can take it and report it to the boss. You don't need to bring mine."

"No, I'm bringing you along today because I actually have another mission. I think the boss has already arranged a reward for you, the pistol design project."

After hearing this, Wang Duoyu stopped being so pretentious, but he still went back to the school infirmary to talk to Zhu Ling about this matter.

When Zhu Ling came to Harbin Institute of Technology, the only things she could do, besides meeting with Wang Duoyu, was to communicate with the doctors in the school clinic.

In any case, it was impossible for her to stay with Wang Duoyu in the Computational Mathematics Department building.

Lin Dehong brought Wang Duoyu to the school clinic, which was quite busy. Yesterday's gas tank explosion had caused many students' ears to ring.

Especially in the dormitory closest to the factory building next door, the window glass was broken and some students suffered minor injuries.

Only then did Lin Dehong understand why Wang Duoyu drafted such a plan. It turned out that the explosion at the factory inspired his idea.

Sure enough, the thinking of a genius is different from that of ordinary people.

When ordinary people hear about a gas tank explosion, their first reaction is to stay away from it, and their second reaction is to gossip about the casualties and losses.

But geniuses can associate and extend things like this, and their thoughts can run wild.

After explaining the situation to Zhu Ling, Wang Duoyu asked her to go to the cafeteria to eat lunch by herself and he would come back later.

Watching Wang Duoyu and the others leave, Zhu Ling's eyes darkened slightly, and she pondered a question in her mind: Is it really okay to keep using contraception?

She has not forgotten her dream of becoming an actress. Although she now works at the Institute of Health, her heart is with Han while her body is in Cao's camp.

Since she wants to be an actress, she definitely cannot do anything like getting pregnant which may cause her figure to go out of shape.

Moreover, she has a face that represents peace and prosperity, and her figure is quite plump, not the skinny type.

Considering her mother's current figure, it will be almost impossible for her to lose weight once she gives birth.

Because she simply doesn't have that kind of perseverance, and then her dream of becoming an actress will be shattered.

But now Wang Duoyu's career is getting better and better. Perhaps it won't be long before his leader will take the initiative to ask him about having children.

What if someone finds out that she has been on contraception, and even Wang Duoyu finds out about it? Wouldn’t that be terrible?

Ugh!
Sorrow!

On the other side, Wang Duoyu and Lin Dehong had already arrived at a unit and met the latter's leader Lu Yangui.

Lu Yangui greeted Wang Duoyu very enthusiastically. After Lin Dehong briefly reported on the gas tank ammunition plan and the plan for cleaning moldy firearms, he looked at Wang Duoyu with sharp eyes and said:

"Comrade Duoyu, your plan is very good. It can be regarded as solving a problem that we are worried about. However, this matter still needs more consideration and may not be implemented so quickly."

In order to ensure that everything goes smoothly, we must act cautiously and not act rashly just because of the plan proposed by Wang Duoyu.

Even so, this is ultimately a very good direction, and as Wang Duoyu said, the Middle East today is in chaos, with various forces fighting and attacking each other.

Moreover, Europe is facing economic recession due to rising oil prices. How can it care about the mess in the Middle East at this time?

So under such circumstances, directly intervening in the affairs of the Middle East will definitely not work.

But what if we do it in secret and sell some weapons?

Can those moldy International brand weapons be wholesaled to those Middle Eastern guys, for example, by weight?

Wang Duoyu said a few humble words, but Lu Yangui continued to talk about the matter and asked him to elaborate.

But how could Wang Duoyu know so much?

He doesn't even know what the current situation is in the Middle East, so he can't just rely on blind guesses, right?
The reason why he knew about the oil crisis was because of foreigners like Chen Xingshen, as well as the magazines and newspapers that Harbin Institute of Technology asked China Resources to purchase from abroad. Otherwise, Wang Duoyu would not have been able to understand foreign information.

Lu Yangui immediately said that he would ask Lin Dehong to take the relevant information to Harbin Institute of Technology in a while so that Wang Duoyu could take a look at it when he had time.

Then Lu Yangui talked about the pistol designed by Wang Duoyu before, and said that the pistol was very good, whether in terms of stability, accuracy or size.

In May last year, Wang Duoyu designed a pistol the size of an adult's palm based on the Type 84 pistol, weighing only 380 grams.

Eight months had passed before Lu Yangui brought up the matter. It was unknown whether it was because he was busy fighting the Southern Monkeys, or because the pistol was not that important, so he brought it up only now.

But no matter what, Wang Duoyu was very happy, after all, this pistol was not shelved.

After meeting the leader, we had a meal together and then went to the award ceremony.
The belated reward did not surprise Wang Duoyu very much, because just like before, it was an honorary reward and a cash reward.

The second-class medal of honor was unexpected but reasonable, but the reward of one hundred yuan was a bit of a surprise to him.

For Wang Duoyu, the cash reward of RMB 100 did not seem to make him very happy. He just felt that leaders like Lu Yangui were rarely generous.

This was also only a small-scale internal award, and not many people knew about it. This is the second medal of honor that Wang Duoyu has received, which is a great thing.

After returning to Harbin Institute of Technology, Wang Duoyu did not share this joy with Zhu Ling because it needed to be kept confidential and the fewer people who knew about it, the better.

Zhu Ling asked him a lot of questions about the army. After all, he was taken to the army so often, so of course she was a little curious.

Unfortunately, most of the requests were rejected due to confidentiality, and Zhu Ling had no way of finding out more details.

Although she was depressed, Zhu Ling had to understand.

A few days later, Zhu Ling, who had spent a week at Harbin Institute of Technology, returned to Beijing.

Wang Duoyu sent another mathematical paper to "Science China·Mathematics", but the next day after he sent it out, Rong Guangxia came to find him.

"Duoyu, how about you help me look at this paper?"

Rong Guangxia's ability is not bad, and his mathematical talent is decent, but Wang Duoyu did not expect that Rong Guangxia was the second student in that batch of students to master the Poincare conjecture in four-dimensional space, and also used the mathematical tools in the paper to verify a small problem in the Milnor conjecture.

After reading the entire paper, he found no problems. However, since Rong Guangxia asked him to help review it, he certainly would not just take a quick look.

Wang Duoyu spent half a day carefully reviewing the paper. After confirming that there were no problems, he said to Rong Guangxia:

"Laorong, no problem. You can submit this paper to the Annals of Mathematics. I will write a letter to the editor-in-chief of the Annals of Mathematics and ask them to pay attention to your paper."

Rong Guangxia obviously hadn't reacted to Zhao Mancang's words. At the desk not far away, Yang Xiuhua and Su Zhenghuai had already stood up and asked in surprise:
"Professor Wang, can his paper be published in the Annals of Mathematics?"

Su Zhenghuai and Yang Xiuhua were of course very surprised, because this was the top American journal "Annals of Mathematics"!

There are not many papers that can be published in each issue. Last year, only 20 to 30 papers were published. Sometimes, only more than 10 papers can be published in a year. It is really better to have nothing than to have something of poor quality!

However, after reviewing it, Wang Duoyu recommended Rong Guangxia to submit the paper to the "Annals of Mathematics" and took the initiative to recommend it to the latter. This shows that Rong Guangxia's paper on proving the Milnor conjecture is of very high quality.

The Milnor formula in arithmetic geometry originates from differential geometry and was first proposed by John Milnor.

Pierre Deligne proposed Milno's formula in arithmetic geometry in 1970 and gave a proof of Milno's formula in the geometric case.

But the Milnor formula for mixed cases remains just a conjecture.

After Rong Guangxia thoroughly studied the Poincare conjecture in four-dimensional space, he came across the relevant papers by John Milnor and Pierre Deligne when choosing the topic of his thesis, and became very interested in the Milnor conjecture.

In Pierre Deligne's proof paper, let X be a smooth scheme over an algebraically closed field with characteristic P>0, f be a morphism from X to a smooth curve, assuming that this morphism has only one characteristic isolated point u, and F be X is a flat constructible layer.

It was because of Deligne's paper that Rong Guangxia was inspired and tried to verify Milnor's formula under mixed conditions. However, it was not so easy to verify the case of divergence.

Fortunately, hard work pays off. After several months of hard work, Rong Guangxia continued to improve and finally proved the numerical Milnor formula in his paper.

Although he proved the Milnor formula under mixed conditions, Rong Guangxia also successfully produced a proof paper.

In Wang Duoyu's opinion, the quality of this paper is still very high and the Annals of Mathematics should publish it.

After receiving Wang Duoyu's confirmation again, Su Zhenghuai and Yang Xiuhua were very happy, but at the same time they felt a little sad.

If Wang Duoyu's paper was published in the "Annals of Mathematics", Su Zhenghuai and the others would not be so envious, but this is Rong Guangxia.

It would be fine if it was just Wang Duoyu, after all, Wang Duoyu is really a monster, but now it seems that Rong Guangxia is also a monster?
What if there are too many talented people in this class in the future? How should these teachers deal with it?

No matter what Su Zhenghuai and the others felt, Rong Guangxia was extremely happy at this moment.

He copied the paper, translated it into English again, and sent it to "Science China Mathematics" and "Annals of Mathematics" in the United States respectively.

Both Chinese and English versions will be published!
Perhaps from this day on, his name, Rong Guangxia, will shine in the global mathematics community.

However, what Rong Guangxia didn't know was that although the Milnor formula was quite famous, it was not a top-level mathematical problem, and there were not many mathematical researchers in the world studying this aspect.

Regardless of whether it is John Milnor or Pierre Deligne, they are both famous scholars in the mathematics community. The former won the Fields Medal in 1962, and the latter won the Fields Medal in 1978.

However, the Milnor conjecture is not a very popular one, and Rong Guangxia only proved the Milnor formula, so he is not very famous.

Wu Congxin, Liu Taoshun and others soon learned about this and were greatly excited.

"Professor Wang, your teaching ability is not much worse than your research ability. How about you teach another class?"

In the office, Wu Congqin looked at Wang Duoyu with fiery eyes and asked with great anticipation.

Liu Taoshun also agreed, saying that this was definitely a very appropriate thing to do.

Harbin Institute of Technology's current education system is still under reconstruction. It urgently needs talented people to take up important positions and vigorously develop the Department of Computational Mathematics.

The latter heard this and said with a smile:
"Director Wu, Professor Liu, this is not an easy task, and it requires the students' own efforts. It's not something I can just open a class on."

There is one point he didn't mention, that is, the students of the classes of 1977, 1978, and even 1979, who were admitted to universities through the college entrance examination, were all fierce dragons.

Why do you say that?

Because these people are a group of people who have been frustrated in the past ten years, and most of them are unable to reach higher peaks through normal paths.

Why did Shen Yueqing from Beijing University of Foreign Languages, a section-level employee in a foreign-related unit, who had a bright future ahead of her, still take the college entrance examination and continue her university studies?

There are also many people in universities such as Peking University and Tsinghua University. In fact, they are already the backbone of their respective fields and have already held high positions such as deputy directors, but they still take the college entrance examination.

To sum up, none of the college students who took the college entrance examination in 1977, 1978 and 1979 were ordinary people.

Millions of people took the college entrance examination, but only a few hundred thousand were admitted. The admission rate was frighteningly low.

Moreover, this group of people have come out of quite difficult situations. They have strong wills, clear goals, and incredibly strong execution abilities.

That is why Xue Xiaoling, Rong Guangxia and others were able to stand out and become the next people after Wang Duoyu who were able to publish papers in American professional journals.

Because they are all very strong and have a certain talent for mathematics, they are so powerful.

But if Wang Duoyu continues to teach, it may not be possible to cultivate a new fierce dragon.

However, Wu Congqin and others tried their best to persuade Wang Duoyu, making it impossible for him to refuse.

"Alright then, Director Wu, please arrange for someone to notify everyone that after the Spring Festival, I will start the course on proving the Poincare conjecture in three-dimensional space. But just like last year, only those who pass the exam can register. Otherwise, don't waste your time."

Upon hearing Wang Duoyu's words, Wu Congqin and others were overjoyed.

This is a great thing.

Unlike the Poincaré conjecture in four-dimensional space, the proof of the Poincaré conjecture in three-dimensional space is extremely difficult.

The theories and mathematical tools such as L-function, space transformation, controlling irregular singularities, manifold collapse, and going back in time are enough to make many mathematics doctoral students feel ecstatic.

What's more, there are many other theories.

On the bulletin board on the first floor of the Computational Mathematics Department's teaching building, when the news that Wang Duoyu would start teaching after next year's Spring Festival was announced, the students in the entire teaching building were excited.

Everyone was eager to sign up immediately.

It’s not just because Wang Duoyu is teaching a course, but also because Xue Xiaoling had previously published a paper in the Duke Mathematical Journal, and Wang Duoyu will be going to the United States to give a report next summer.

The main topic of Wang Duoyu's report in the United States was about the Poincare conjecture and capping papers in three-dimensional space, a total of three papers.

This time, after the Spring Festival next year, the course taught by Wang Duoyu will be more detailed than the report next summer, so no one wants to miss this opportunity.

Secondly, everyone also hopes that, like Xue Xiaoling, their papers can be published in professional journals in the United States and become famous.

Life is nothing more than the pursuit of fame and fortune.

After the meeting in December 1977 and 1978, the great wave of reform and opening up officially arrived. Economic construction became the most discussed topic, and following the money became an urgent idea for many units or people.

The word "money" appears more and more frequently in daily life, and many old ideas about speculation and profiteering are also slowly being changed.

Fame and fortune have also been gradually magnified.

In such an era, the students of the Department of Computational Mathematics at Harbin Institute of Technology were like hungry wolves and did not want to miss this opportunity.

It can be predicted that in addition to the final exams, they will all work harder to study topology-related knowledge.

At the library, the latest topology-related professional books are once again in short supply!
Many students were unable to borrow books and came to the teachers for help. Director Wu was very annoyed by the teachers and had to pay for it out of his own pocket and ask the printing factory to print more relevant books as soon as possible.

Almost all students from the classes of 1977, 1978 and 1979 will sign up for the exam after the Spring Festival.

Even Xue Xiaoling, who is already successful, is actively preparing.

why?
If Wang Duoyu started the course without mentioning registration, but instead allowed the 39 students who enrolled in July and August last year to attend directly, then Xue Xiaoling would definitely not have to worry.

But the announcement clearly stated that everyone needed to pass the exam before they could register.

Therefore, not everyone will be able to attend next year's courses.

Even Xue Xiaoling cannot guarantee it 100%.

Xue Xiaoling still remembered that in November, Wang Duoyu told her that if she didn't work hard, then her paper on the proof of four-dimensional manifolds would be the pinnacle of her life.

She certainly doesn't want to stand still, so she will work harder.

Even Xue Xiaoling was extremely nervous and tried hard to move forward, and the others were even more so.

With the arrival of late January, the final exam week is about to come. But at this time, a junior student Zhu Chengwu submitted three papers, which were published in "Science China·Mathematics" and "Acta Mathematica Sinica" respectively.

This news broke out suddenly, leaving everyone very surprised.

Rong Guangxia and Xue Xiaoling soon found out that Zhu Chengwu was in the four-dimensional space thesis class taught by Wang Duoyu last summer.

Wu Congxin and Liu Taoshun also quickly confirmed the matter and became even happier.

After Wang Duoyu heard the news, he was delighted and relieved.

As the final exam week was approaching, Zhou Sitong, Zhao Jiawei and others were finally freed from the fifth floor.

There have been a lot of big news in Harbin Institute of Technology recently, but Zhao Jiawei and his friends didn't have much gossip about it because they had been clearly arranged by Wang Duoyu.

The distributed computer project is now divided into two parts. One small part is the data processing department that is dedicated to making money, and the other part is where most team members are learning relevant theoretical knowledge.

Once Principal Liu transfers the remaining 4.5 million yuan, the entire project will be officially launched.

Exam week is quickly coming to an end, February is almost here, and winter break is about to begin.

But for Zhou Sitong and others, the real test has arrived.

Because after the final exams, they have to stay in the project department.

On January 31st, Liu Deben finally showed up and brought good news to Wang Duoyu.

"Duoyu, our electric bicycle company has already received hundreds of large orders. Once these orders are completed, we will be able to earn 5.7 million RMB in revenue."

"After calculation, the profit will be nearly two million. We will invest 80% of this money into your distributed computing project."

"But Duoyu, you have to give me a definite answer. Can distributed computers really be sold at high prices in the future?"

In the office, after listening to this, Wang Duoyu said to Principal Liu:
"Principal, what kind of confidence do you need from me? Isn't what I did before enough?"

Upon hearing this, Liu Deben fell silent.

Seeing this, Wang Duoyu continued:

"I'm sure you, Principal Liu, read the newspaper regularly. Our country will definitely launch more projects this year. Barring any unexpected events, this year's mid- to large-scale projects will undoubtedly be significantly more than last year's."

"The more projects there are, the greater the demand will be. Whether it's a distributed computer project or an electric bicycle project, these are essential demand points for most economic construction projects."

"So, Principal Liu, you don't need to worry about this. Instead, I suggest you focus on Diao Pai Company's production safety and technological research and development."

"There's no need to worry about the technical aspects of my distributed computing project. I'll also be following up on the personnel training. The question now is, when will the remaining 4.5 million yuan in funds arrive?"

"If you, Principal, are too stingy, then it will be difficult for me to produce the product so early."

After Wang Duoyu finished speaking, Liu Deben immediately stated that he would definitely prepare the funds as soon as possible and purchase the equipment needed for the project as early as possible.

After talking about this, Liu Deben suddenly slapped his forehead and said:
"By the way, I heard from Secretary Li that Professor Xia Peisu from the Institute of Computing Technology of the Chinese Academy of Sciences has submitted a parallel computing project. I'd like to ask you if this project will have a negative impact on our distributed computing project?"

Wang Duoyu wanted to laugh when he heard this, but on the surface he threatened:
"Of course it will have an impact. If Professor Xia completes his research and development before us, then when parallel computers become available, our distributed computers won't have much of an advantage. Unless we continue to increase our investment, we won't have much of a chance of success."

Distributed computing is a new computing method that breaks down the application into many small parts and assigns them to multiple computers for processing. This can save overall computing time and greatly improve computing efficiency.

Parallel computing is an algorithm that can execute multiple instructions at a time. Its purpose is to increase computing speed and solve large and complex computing problems by expanding the scale of problem solving.

The so-called parallelism can be divided into temporal parallelism and spatial parallelism. The former refers to pipeline technology, while the latter refers to the concurrent execution of calculations by multiple processors.

From the above definitions, it can be seen that distributed computing and parallel computing do have overlapping technologies to a certain extent, and the latter almost completely includes the former.

But in fact, these are two technologies applied in different fields.

You should know that the core idea of ​​distributed computing is to share scarce resources and balance the load, which means that it needs to deal with projects that require an astonishing amount of computing, which is absolutely impossible to complete within an acceptable time by relying solely on a single computer or an individual.

At the same time, it should be clear that the construction and maintenance of supercomputers are very expensive. For example, the development cost of the Galaxy-1 supercomputer alone is in the billions.

It was developed at the Computer Research Institute of the National University of Defense Technology in collaboration with many other units. The entire project is very large and time-consuming, but it must be completed.

Because there is currently no computer in our country that can reach 100 million times per second, the emergence of Galaxy No. 1 will fill the gap in this regard in our country.

Supercomputers haven't appeared yet, and even if they did, it wouldn't be easy to apply for one.

Last time, the amount of calculations that Team Leader Yu of Shanghai Unit 304 needed to complete was actually not that astonishing.

In short, distributed computing is, to some extent, a complement to parallel computing.

The application areas of parallel computing are those large and complex calculations, which are not just about the sheer amazing amount of computing, but also involve more complex mathematical models.

Therefore, it is not entirely unreasonable for Wang Duoyu to "scare" Liu Deben in this way.

However, his project has already started, and even if other equipment is not in place yet, he will definitely not be caught up by Xia Peisu.

Liu Deben was indeed shocked when he heard this, and he immediately said that he would immediately arrange for relevant personnel to take out the funds as soon as possible to purchase the equipment that Wang Duoyu had previously submitted.
