Military Industry of Great Powers: Build the Strongest Flanker.

Chapter 233: After working for half a year, I can’t catch up with the computer for ten minutes

The potential significance of Longteng

This should be the last time Director Liu participates in external research during his term of office.

"How much does this computer cost?"

Zhao Guoqing said: "Let's see how many sets you want?"

"..."

"What if we want a hundred units?"

It’s only one hundred units. Teacher Xiao Zhao shook his head and said, “About 20 million yuan!”

"So expensive!" Director Liu shook his head.

Zhao Guoqing picked up an x109 graphics card, uncovered the radiator on it, pointed at one of the graphics card chips and said to Director Liu: "Director Liu, this chip integrates nearly million transistors. You said you need to stuff so many transistors into it?" How much does it cost to get into a place the size of a fingernail?”

"..."

Everyone was shocked, thirty million! This order of magnitude is too scary!

Ji Hongbo smiled at Director Liu and said, "Director Liu, in 87, the country introduced an IBM mainframe with similar performance to this one. How much did it cost at that time?"

This comparison came out. Director Liu said: "I remember spending more than 20 million US dollars at that time. Oh, it makes me sad to think about it. The Americans told us that it can only be used for civilian purposes, and they also sent three people to monitor here. , all computing tasks must be checked by these three people before they can be operated on the computer, and they won't let us operate it easily!"

"So, this computer is not expensive!"

Zhao Guoqing said: "Director Liu, Institute 102 must also develop sustainably. Where are the costs? Only a dozen x109 graphics chips can meet the requirements in one wafer. Besides, the exploration of more advanced processes also costs money. Yes, the money is in hundreds of millions!"

The krypton fluoride 248nm laser lithography machine can perform 130nm process at its theoretical limit. With the addition of multiple exposure technology, it can even explore the 90nm process.

But now, whether it is ASML, Nikon, or Canon, for the sake of efficiency, they have all adopted stepper lithography technology. Compared with the previous projection type or contact type, the efficiency has been improved, but the accuracy is still not enough.

Institute 102 has trial-produced a 130-nanometer process, with a yield rate of less than 3%. The accuracy requirements have exceeded the limits of the detection tools on the photolithography machine...

Theoretically, the manufacturing process of Institute 102 has reached 90 nanometers, but it is hampered by the photolithography machine!

"CLP 14 is definitely needed, and Longteng x109 can definitely help us establish a computer simulation model of radar waves, which will be a great help to us!"

Tu Jinda and Zhao Zhongshu represented Cheng Fei, who was naturally unwilling to lag behind.

Zhao Zhongshu said: "On National Day, doesn't Institute 102 have a software for designing missile shapes? Can you give it a try!"

Designing missiles is much less difficult in terms of aerodynamic appearance than designing aircraft, but the principles are similar and the various indicators are also similar!

Zhao Guoqing nodded. As soon as Longteng x109 appeared, he began to move the programs in the UNIX system to the new computer one by one.

The graphical framework of the software has been set up, and there are no longer commands on the taskbar.

Teacher Xiao Zhao skillfully constructed a hyperboloid model.

"Head wind speed is set from 100 kilometers per hour to 500 kilometers per hour!"

"Finite element analysis begins!"

The entire surface is divided into 376 quadrilaterals. After the calculation is completed, the stress curve of each quadrilateral with time wind speed can be seen.

Zhao Zhongshu's eyes were dumbfounded. He looked at the time and found that such a complicated calculation only took less than seventeen minutes.

Tu Jinda asked Zhao Guoqing: "Can you simulate an airplane wind tunnel?"

Zhao Guoqing shook his head and said: "Mr. Tu, the computing power may not be enough. Now we can only do missile supersonic wind tunnel simulation. It should be OK!"

"..."

Accurate model calculations, even with a Longteng x109 computer, can take several months to simulate complex changes in the wind tunnel. However, if the model is built crudely, you will not get the desired results. Of course, if you don't care about time, you can still do it. Tu Jinda listened to Zhao Guoqing's words and said: "It's not bad. If we can't calculate it together, then we can separate it into individual items..."

The nose can be taken out separately, the canards can be taken out separately, the wings and tail can be taken out separately, and then finally integrated, the model can be taken to the wind tunnel for testing. Isn't that how it was designed before...

Zhao Guoqing said to Tu Jinda: "Mr. Tu, there is no need to regret it. 102 estimates that if the manufacturing process reaches 90 nanometers, we can build a computer with a computing power of billion times. By then, we can directly simulate the data of the entire aircraft, not only simulating the aircraft wind. Holes can also simulate nuclear explosions, atmospheric movements, earthquakes, and solar particle bursts..."

Zhao Guoqing opened the MATLAB software installed on his computer.

This is a commercial mathematics software produced by the American MathWorks company and is used in data analysis, wireless communications, deep learning, image processing and computer vision, signal processing, quantitative finance and risk management, robots, control systems and other fields.

The MathWorks company has been fully acquired by Envision Investment, which is solely owned by Zhao Guoqing. Naturally, this software can also be said to be privately owned by Comrade Zhao Guoqing. He immediately established a MATLAB research center on Hong Kong Island.

MATLAB is a very practical tool that can be used to build various mathematical models.

Such as phased array radar.

Teacher Xiao Zhao typed in the eight-by-eight phased array array on the software, and a three-dimensional picture of the radar beam quickly appeared on the computer.

Also shown above are the signal gain strengths of the main lobe and side lobe...

"..."

Ji Hongbo's eyes widened.

"National Day, there is such a good thing, why are you hiding it?"

This is so useful for radar design.

Zhao Guoqing smiled and said: "This is a newly developed function, but it didn't exist before!"

Ji Hongbo said: "Can I do irregular arrangements?"

Zhao Guoqing said: "How do you want to arrange it?"

Ji Hongbo started directly by himself, trying T-shaped, L-shaped, and ring-shaped. He had studied these, and the result...

"It's incredible!"

Director Liu stepped forward and said, "What's wrong?"

Ji Hongbo said very frustrated: "Director Liu, I feel that the work I have done in half a year cannot keep up with what this computer can do in ten minutes!"

"..."

Zhao Guoqing realized that Pang Guohong had basically said nothing until now. Sometimes he was thinking and sometimes recording, but he looked at him from time to time...

Well, Teacher Xiao Zhao didn’t take it seriously and continued to demonstrate the functions of the computer.

Guys, hurry up and pay...

……

The speed is very fast. After joint certification by various ministries and agencies, in just three days, 102 has received orders for 86 units, with a unit price of 2000 million yuan and a total value of 17 billion yuan.

17 billion seems like a lot, but compared to Mr. Zhao’s investment in Longteng x109, it’s a huge loss.

From the processor to the chipset, from the bus standard to various interfaces, from the graphics card to various components, the software and hardware environment requires a lot of investment in manufacturing.

If there weren't other industries that continued to subsidize us, I would really be afraid that we wouldn't be able to continue playing. Semiconductors are really too expensive!
