The military-industrial scientific research system of the academic master.

"Do you want to come with me?"

In the computing center, Chang Haonan carefully put the hard drive containing the data into a box while asking Yao Mengna, who was processing a batch of mechanical data next to him.

The latter raised her head and hesitated for a while. It could be seen that she also wanted to take the opportunity to return to the capital, but in the end she shook her head.

It is true that following Chang Haonan to the computer research and development center can definitely gain something, but Yao Mengna knows very well how much she weighs——

She has learned a lot from Chang Haonan during this period, but the bottleneck is that she doesn't have many opportunities to try it.

Therefore, it is now even more necessary to apply new knowledge down to earth.

"No, I plan to stay here to help Lin Gong and the others continue to promote the matching of digital design and production and manufacturing processes. In addition, I also want to take advantage of this opportunity to optimize the entire machine of Project 83 to slightly change the canopy. "

"Cockpit cover?" Chang Haonan raised his head curiously.

The other party has never disclosed such an idea before.

"Yes, I looked at the photos you took in the sky and found that the traditional three-piece windshield has a very poor field of vision. Comrade test pilots in the Air Force had similar reactions, especially after installing a HUD. It was even worse. Left and right There is almost a blind spot of about 30° in front.”

"So I was thinking if I could change the front windshield of the canopy to a whole arc type, the field of view would be much better."

Yao Mengna nodded and took out two photos from the notebook next to her.

One is of the J-8-3, and the other is of the Su-27.

"I specifically consulted Mr. Yang, and he told me thoroughly that in the No. 27 project where we introduced and domestically produced the Su-120, there is a complete set of AO120 plexiglass technologies required to manufacture an integral arc-type front windshield. As for the small batch trial production during the flight test phase, it can be completely solved by relying on the small amount of finished AO materials currently saved."

Obviously, this was not a hot-headed decision, but one that was well thought out and proven feasible.

Chang Haonan just asked casually, and he was also happy to see that capable scientific researchers like Yao Mengna and Lin Shikuan could solve problems alone through their learned abilities after receiving his help or guidance.

"Well, I wish you all the best."

"Same for you."

……

Yang Xia, the deputy director of the Secretariat Office assigned by Yang Fenghao to Chang Haonan, is a woman in her forties who looks very capable.

Under her arrangement, Chang Haonan basically didn't have to worry about anything along the way. He checked into a guest house of the Chinese Academy of Sciences very smoothly, and came to the Institute of Computing Technology early the next morning.

Using a supercomputer is different from an ordinary PC. You do not have to actually enter a data room filled with cabinets.

In fact, it is impossible for outsiders to enter there casually.

As for directly connecting the computers brought from outside to the server physically...

Although it is technically impossible, if you really dare to do this, you will probably be able to secure the iron rice bowl provided by the country for the rest of your life.

The kind that you can’t even think about.

However, compared to later generations where you can directly apply for and log in to the cluster remotely, at this time only specific computers can connect to the supercomputer through xshell or ssh.

"Dr. Chang, I'm waiting for you in the reception office at the door. If anything happens, you can call my pager."

Because Yang Xia was not a technician, she did not follow him into the work area on the second floor.

Under the guidance of the internal staff of the institute, Chang Haonan came to the door of an office with several terminal computers.

But there was no one inside.

A few minutes later, with the sound of hurried footsteps, a young woman with a bun trotted over.

"Huh... are you Dr. Chang Haonan?"

The woman looked at Chang Haonan, who was leaning against the wall and waiting, and asked breathlessly.

"Yes, I am."

Chang Haonan nodded, and then looked directly into the office beside him.

It's not that he doesn't want to say hello or say a few words.

But if you don't turn your head and pretend to look at the scenery, it's really difficult to take your eyes away from the opponent's chest that is surging from running...

"Sorry, sorry, I'm Xu Yang, a researcher at the Institute of Computing Technology. There was a small problem in the computer room just now, so it was delayed for a while."

This self-introduction shocked Chang Haonan and turned his attention to the other party again.

Researcher of the Chinese Academy of Sciences is not a casual title, but a serious professional title.

Really high-end.

The Xu Yang in front of him looked like he couldn't be more than 30 years old at most.

Twenty years later, senior executives under the age of 30 might not be so rare, but this was 1996.

Now Chang Haonan finally knows how those people who heard that he was just an undergraduate felt before.

It's so terrifying...

Xu Yang, who was opposite him, seemed to have long been used to this kind of reaction from others. After briefly introducing himself, he led Chang Haonan into the office.

"The task I received is to assist you in completing the entire calculation, so which part do you need my help with?"

"I have already written the basic calculation program, but it would be better if you could help me complete part of the parallel computing development using MPI."

With systematic guidance, of course Chang Haonan can write himself, but no matter how efficient he is, he is still an individual. It would be great if he could have more power. "

"It would be much easier if you also know programming. How did you bring the data? Tape, floppy disk or..."

Chang Haonan took out the box containing the hard drive and a calculation instruction from his backpack.

Although he himself does not need this thing, there are other people involved in the August 3rd Project, and files need to be kept, so he still needs to write one.

"Hey, the hard drive is pretty good."

Xu Yang took the hard drive, plugged in a cloth-like PATA interface data cable, and then helped Chang Haonan open another terminal.

Two people can read files on the hard drive at the same time, so they can work at the same time without affecting each other.

"Genetic algorithm?"

Not long after opening Chang Haonan's program, Xu Yang saw some clues.

"No, it's another...differential evolution algorithm?"

"Have you started using the differential evolution algorithm for optimization?"

She sounded clearly excited.

"Do you know this algorithm?"

Chang Haonan was also stunned. In fact, he was not even sure whether this algorithm was born in 1996.

"Well... I actually studied for my PhD at Berkeley. Strictly speaking, I participated in the development of this algorithm."

"what?"

The shock that Xu Yang brought to Chang Haonan was probably not much different from what the latter brought to Du Yishan before.

"But when my teacher originally thought of this algorithm, it was just to solve the fitting problem of Chebyshev polynomials, and it was only completely developed last year after I graduated. This is the first time I have seen it in other countries. Applications in the field, has the domestic field of intelligent optimization algorithms developed to this extent?"

"..."

Looking at Xu Yang with a surprised face, Chang Haonan didn't know how to answer for a moment.

There should be another update for the leader later.
