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

Chapter 115: Complete the programming of 50000 paper cards in two days? Become famous as early as possible, mainlanders are ungrateful
"Team Leader Wang, are you saying that you want us to stay at Harbin Institute of Technology for two days? You want us to complete the programming work within two days and then let us take the main memory back to Beijing?"

In the office of the Department of Computational Mathematics, Shan Yunbo and Chu Yuheng looked surprised, even extremely shocked.

Especially the latter. He wanted to laugh at Wang Duoyu's joke just now, but now it seems that he is the clown.

Because they saw Wang Duoyu busy programming with a paper tape puncher and an hzd5-controlled typewriter.

Just now they thought that Wang Duoyu might not understand it very well, but now his technique is quite skillful, as if he has no sense of unfamiliarity at all.

Wang Duoyu was even able to chat with the two of them while typing on the typewriter "blindly".

It's so arrogant!

Even in the Institute of Computing Technology, only highly skilled technicians can perform skills like 'blind typing'.

But when did Wang Duoyu learn this skill? Was it something he was born with?

Moreover, it would be fine if he could just type blind. At most, Wang Duoyu might have had some contact with computers at the Institute of Mathematics or the Computer Science Institute, or he might have had special practice at Harbin Institute of Technology.

However, Wang Duoyu actually asked them to wait for two days, and then he would complete the programming work within two days?
This is simply nonsense.

Who is so good at programming?

What's more, Wang Duoyu completed this programming work independently?
This is simply an international joke.

According to the previous discussion between Wang Duoyu and Professor Xia Peisu, the system structure of this high-speed array processor is now constructed using parallel technology, so when designing it, he needs to outline the entire framework.

In order to prevent Shan Yunbo and Chu Yuheng from going back and forth, Wang Duoyu asked them to stay in Harbin Institute of Technology for two days. He tried to program the framework within two days and then let them bring the main memory back to Beijing.

As we all know, there are independent adders and multipliers in the arithmetic unit, which can work in parallel.

An addition and multiplication operation can be completed within one machine beat, that is, one clock cycle.

To achieve this, the numbers required for the operation must be provided within one beat.

The high-speed array processor designed by Wang Duoyu and Xia Peisu uses multiple memories to provide the data required for calculations.

This means that Wang Duoyu needs to complete a lot of programming.

You should know that the current paper card punching machine can hold 62500 paper cards, which is equal to 5MB.

Wang Duoyu wanted to complete the programming of a "number" within two days, which meant that he would need about 4MB, which is equivalent to 4 paper cards.

Such a workload is undoubtedly terrifying.

Therefore, Shan Yunbo and Chu Yuheng were so surprised after hearing it.

"Well, you can stay for two more days. Including today, it should be four days in total, so there is still plenty of time."

After a pause, Wang Duoyu continued with a smile:

"If you return to the capital and I notify you to come over a few days later, wouldn't that be even more troublesome?"

"Also, you are in my team. If you have any technical questions, you can consult me ​​in the next few days. I will do my best to answer your questions."

"So what's the problem now?"

Wang Duoyu pays attention to efficiency in his work, respects the fruits of each other's labor, and likes to combine work and rest.

But he doesn't like to play and relax before finishing his work. If he does that, he won't be able to have fun.

At the end of September, after completing his paper proving the Poincare conjecture in four-dimensional space, he allowed himself to relax for nearly two months.

For him, reading is one of the ways to relax.

So now, in late November, he has begun to prepare to continue writing his thesis.

The brain cannot be allowed to relax for too long, otherwise it will easily rust and become dull.

Upon hearing this, Shan Yunbo and Chu Yuheng shook their heads and turned to leave the office.

However, the two of them kept looking back and couldn't figure out how Wang Duoyu did it until they walked out of the office.

Two days later, Wang Duoyu had completed the programming and handed the main memory to Shan Yunbo and Chu Yuheng, saying:
"After you return to the capital, please hand this main memory over to Professor Xia. I will continue programming it and add more 'numbers' over the next period of time."

The use of parallel technology means that instruction fetching, address processing, loop calculation and other necessary operations must be completed within the same beat, so parallel data channels need to be provided.

In other words, if the "number" is not enough, the array processor is meaningless.

In addition, if you want to further increase the computing speed, you can also use multiple adders and multiple multipliers.

There can even be independent dividers and square root extractors that can all work in parallel.

Wang Duoyu is ambitious, and Professor Xia Peisu, as the mother of domestic computers, is equally ambitious. Otherwise, he would not have worked so hard to apply for this high-speed array processor project.

Because Xia Peisu is already 55 years old this year, to be honest, according to her age, she can retire.

However, the scientists of this era, whether it is Hua Luogeng, Xia Peisu, or Qian Xuesen, are a group of people who are very worthy of respect, because they have truly devoted themselves to their work and have been fighting on the front line of scientific research all their lives.

Therefore, when Wang Duoyu joined this high-speed array processor project, he already had many ideas.

High speed is the real king, and it is also the meaning of the existence of array processors.

Only after the speed is increased will the next step be to consider issues such as "ultra-small".

In fact, foreign countries have not yet fully entered the stage of developing ultra-large-scale integrated circuit computers. It can only be said that they are in the starting stage. China can definitely catch up with the United States at this time.

For example, in March of this year, the month of the National Science Conference, the arduous task of building the Galaxy-1 supercomputer was assigned to the National University of Defense Technology to lead, with more than 20 scientific research and production units and user units across the country working together.

The Galaxy No. 1 supercomputer project is currently the largest computer research project in our country. Unfortunately, Wang Duoyu had no chance to join this project at that time.

But he didn't want to join it at the moment because it was too complicated and there were too many researchers on the project.

Wang Duoyu was very reluctant to work on any project that involved too many complex interpersonal relationships. He didn't even want to coordinate with Shan Yunbo and Chu Yuheng, let alone others.

After Wang Duoyu finished speaking, Shan Yunbo and Chu Yuheng were already stunned and did not react for a long time.

"Okay, you guys go back to the capital first. If anything happens, just call me."

Downstairs in the office building of the Department of Computational Mathematics at Harbin Institute of Technology, Shan Yunbo and Chu Yuheng, who were holding the main memory, looked at each other. The strong wind had cleared their minds, but they still couldn't believe their ears.

Even though they couldn't believe it, they had just seen the long paper tape on the paper card punch machine in the office, and it definitely couldn't be faked.

So, Wang Duoyu has really completed such a huge amount of programming work.

It’s incredible!
Snapped!
Shan Yunbo suddenly slapped Chu Yuheng, who cried out in pain:
"Yunbo, why did you hit me suddenly?"

"You know it hurts, right? So it's true? Holy shit, Team Leader Wang is amazing! He said it was four days, but it was actually less than seventy-two hours. Excluding time for sleeping and eating, there's also time for us to ask questions."

hiss!
Shan Yunbo took a breath and shuddered instantly because it was too cold.

"I'm afraid the time Team Leader Wang actually spends programming is no more than forty hours."

Chu Yuheng rolled his eyes and said unhappily:
"Alright, alright, let's hurry back to the capital. It's freezing outside. Let's go!"

At this moment, a group of people suddenly appeared in front of them, but they didn't recognize them. However, some of them obviously did not look like people from the mainland.

why?
Because these people were dressed very fashionably, especially the female comrade. Although she was wrapped in thick clothes, her exposed face was as beautiful as a fairy and a painting.

"Comrades, please come this way. Our Computational Mathematics Department office building is here."

Wu Congxin, Liu Taoshun and others led the way in front, and it was Liu Deben who talked to Zhou Jiamin, Kang Xiaofei and their leaders.

Shan Yunbo and Chu Yuheng did not know each other, but they knew Wu Congyin and Liu Taoshun, so they greeted each other with a smile.

After passing each other, Shan Yunbo and the other man left, but Zhou Jiamin's face left a very deep impression in their hearts.

In the 1970s, almost all women in mainland China did not wear makeup.

Except for dancers like Liu Xiaoli, she is required to do this for her job after all.

They were not used to seeing lesbians wearing makeup, so when Shan Yunbo and the others saw Zhou Jiamin for the first time, she had beautiful makeup and a good foundation, and they fell in love with her immediately.

If we really want to talk about fairies, Liu Xiaoli and Zhu Ling are the real fairies. Their beauty and temperament that can last a lifetime at first glance are enough to make most beauties become background figures. Even if Zhou Jiamin dresses up more gorgeously, she cannot be compared with them.

In the office, Zhou Jiamin and his colleagues finally met Wang Duoyu, the mathematical genius who was praised to the skies by American newspapers. After some polite greetings, the interview officially began.

This morning, just when Wang Duoyu was about to finish his programming work, Liu Deben and Wu Congqin found him and explained to him the interview with the Hong Kong Commercial Daily reporter.

After many twists and turns, the higher authorities had approved Zhou Jiamin's interview request. Liu Deben had no way to stop her, so he brought her into the school.

After Wang Duoyu learned about this, he had no way to refuse. It was not a big deal anyway. However, he still made one request, which was that no photos could be taken.

However, during the interview, Zhou Jiamin still raised questions about the requirement of not taking photos.

"Mr. Wang, you're very handsome, and your paper was published in a top American mathematics journal. This is a good thing worth publicizing. Why can't you take a photo?"

The Hong Kong Commercial Daily was founded in 1952. It is a major financial newspaper that focuses on economic reporting and aims to facilitate economic and trade exchanges between Hong Kong Island and the Mainland. It has always adhered to a patriotic and Hong Kong-loving stance.

That's why Zhou Jiamin and his team were able to come to Harbin Institute of Technology to conduct the interview as soon as possible, and they also hoped to get Wang Duoyu's permission to take a frontal photo.

"I don't like taking pictures very much!" Wang Duoyu shook his head unwillingly.

The main reason is that they don’t want to be recognized by others. When celebrities seem to have unlimited glory, they are actually hiding dangers. Even though it is just an interview, the possibility of being recognized by many people is not high, but who knows if there is anyone who is interested?
If someone remembers you, your life will be in danger in this era!

Zhou Jiamin and the others' eyes widened. What had they heard? Wang Duoyu said he didn't like taking photos?

Are there still people who don't like taking photos these days? That's really rare. Almost everyone is interested in taking photos. Besides, Wang Duoyu is so handsome, he must have been admiring himself in the mirror a lot, right?
Kang Xiaofei's mouth twitched, and he looked down at his camera, feeling as if his career had suffered a 10,000-ton critical blow.

Liu Deben couldn't understand it either, and blurted out, "Mr. Wang, why don't you like taking pictures? You can't miss such a good opportunity!"

Everyone in the office looked at Wang Duoyu, with curiosity, confusion and doubt in their eyes.

The higher authorities have allowed the Hong Kong Commercial Daily to interview Wang Duoyu, which shows that this time Wang Duoyu accidentally seized the opportunity of the times and was able to soar to success.

In her collection of novels, Eileen Chang said: "Oh, it's better to become famous early! If it comes too late, the happiness will not be so satisfying."

Zhou Jiamin has always agreed with Zhang Ailing's words and believed in them without a doubt.

But Wang Duoyu is afraid of becoming famous. What's going on?

"Principal, I simply don't like taking photos. There's no need to ask too many questions." Wang Duoyu shook his head without further explanation.

The interview was almost over here. Even if Zhou Jiamin wanted to ask something else, Wang Duoyu just dealt with it lightly with vague words.

There is really nothing good to interview him about. He is not in the entertainment industry, so why does he need to be so famous?
After leaving Harbin Institute of Technology, Zhou Jiamin was still very upset and puzzled, complaining: "I have never seen such a person. He is obviously a mainlander, but look at how capable he is. I didn't know he was a big star."

"Yeah, if you don't want to be photographed, why would you accept the interview?" Kang Xiaofei agreed. He has been in this industry for several years, but has never felt so frustrated.

Their leader frowned upon hearing this. "Alright, cut the smack. We're already doing a great job completing our interview. What else do you want? You didn't grow up in mainland China, so you don't understand this place."

"Oh, forget it. Hurry up and let's get back to Hong Kong Island and report this news as soon as possible."

Zhou Jiamin and Kang Xiaofei finally calmed down, but when they thought about the next report, they became excited again.

Just as the Hong Kong Commercial Daily was about to report on the mathematical genius, Shiing-Shen Chern and Shing-Tung Yau arrived at Beijing Nanyuan Airport by plane.

Finally returning to his hometown, Chen Shiing-Shen was very excited from the moment he boarded the plane to the moment he landed at Nanyuan Airport.

I was even more excited when I saw old friends such as Zhou Peiyuan, Hua Luogeng, Su Buqing, Duan Xuefu and others waiting for me at the airport.
