Chapter 776

This is a time of neglect.

When it came to large-scale integrated circuits, China quickly fell behind and was forced to adopt foreign chips. After that, China began to focus on procurement and completely lost its R & D ability.

All kinds of supercomputers in the later Han Dynasty sound advanced in performance and live at the advanced level in the world. There are several supercomputers in the top ten in the Han Dynasty.

However, supercomputers such as Tianhe II still use Intel's Xeon processor. With the eagle country export ban, advanced chips will not be available.

It was not until the birth of the new computer, Shenwei Taihu light supercomputer, that 40960 "Shenwei 26010" multi-core processors independently developed by Han were installed. The multi-core processor adopts 64 bit independent Shenwei instruction system, with a peak performance of 1.25 billion times / s and a continuous performance of 930 million times / s.

It can be said that the procurement of foreign chips for computer systems began in the late 1970s.

Qin Guan's access point is already too late.

These advanced microprocessors, godson-1 and hanson-1, were developed in the last two years. Domestic computer institutes also began to hope to study supercomputers equipped with these processors, but they have not been commercialized. The supercomputer in front of us uses IBM chips.

Put these aside. The assembly process is really poor. This kind of welding technology can't go to hell without failure!

Qin Guan couldn't get in and watched everyone repair it. All of a sudden, from noon to afternoon, from afternoon to evening, until three o'clock in the middle of the night. Finally, Colonel Chen with red eyes said, "here, the resistance is faulty welding!"

The pin of this resistor is surrounded by rosin. Usually, there is a little solder in contact with it, but after a long time, the salt corrosion at sea, the shaking of the ship and the vibration of the engine finally made it completely disconnected and failed. Although it is mainly integrated circuits, there are still some discrete components. If any component fails, it may lead to overall failure.

"Get the electric soldering iron!" Colonel Chen started himself, heated the electric soldering iron, soldered the resistance pin again, and then returned to the top. Sure enough, the fault was eliminated.

"Mr. Qin, you haven't gone to bed yet?" Colonel Chen noticed Qin Guan who had been observing nearby and asked him.

Qin Guan looked at the exhausted technicians and said, "everyone doesn't feel hard. What else do I have to work hard? However, I feel that our system is not very reliable!"

Who knows if there will be any trouble when it is needed? The welding level of this computer is not good. At the same time, it also lacks an appropriate self-test system.

After all, the previous supercomputers were only used on land. This time they went to the sea.

Colonel Chen also looked helpless: "yes, there are some problems with this system, but we have no replaceable products for the time being."

If you want to carry out aerospace measurement and control, the computer performance you need must be particularly advanced. The stronger the computing power, the better.

"What do you think of the computers produced by our Hanshin technology company? If necessary, we can give priority to our measurement and control ship at any time."

After hearing Qin Guan's words, Colonel Chen continued to shake his head: "President Qin, the computer of Hanxin technology company is indeed advanced in performance, but it is still impossible to replace our mainframe computer. Its computing power is simply not enough."

Can a microcomputer do the work done by a mainframe?

Yes.

Look at the future, except for the supercomputers of national projects, those mainframes, medium-sized computers and so on have declined. Due to the rapid development of VLSI, tens of millions or even hundreds of millions of transistors can be gradually integrated on one chip. Computers that have developed rapidly in the 1980s and after are "microcomputers" and super "microcomputers" used by ordinary individuals, that is, high-performance computers that can form servers or parallel processing, Other kinds of computers can't compete with microcomputers because of their cost performance, so they naturally gradually withdraw from the stage.

The processing power of a microcomputer in the future is much faster than that of the most advanced large-scale computer.

In short, take the i7 processor commonly used in later generations, such as i7 980X extreme: 3.33ghz * 6 * 4 = 79.92 gflops, that is, i7 980X extreme has peak computing power of 79.92 billion times per second.

CPU peak computing power (floating point operations per second) = CPU frequency × Number of CPU cores × Number of floating-point arithmetic units.

It can be seen that if you take an i7 host from later generations, it will be enough to replace so many big guys in the computer room.

Therefore, in later generations, computer companies that still hold on to mainframes and fail to adjust their strategies in time, such as CDC company and Wang'an company, have closed down one after another.

Of course, at present, our own microcomputer processing capacity is not enough, but there are still other ways.

"We may not have enough computing power in a single computer, but we can connect many computers online for computing," Qin Guan said "For example, we provide 50 Han core computers, which is enough to complete all the tasks of aerospace measurement and control, but we only need to develop special software. At the same time, if these computers are networked, there will be surplus. Once one of them fails, it will not affect other computers, and the whole system can continue to operate."

One is not enough. It can be connected to the Internet. Once connected, it can fully meet the needs.

In later generations, some people want to carry out complex operations, but they can't borrow supercomputing. The idea is to use other computers on the network to help calculate. One is not enough. What about 1000 or 10000?

Now, as long as 50 Hanxin computers can completely replace this unreliable mainframe.

After hearing Qin Guan's words, Colonel Chen thought: "yes, we can try this time. If we can succeed, President Qin, you are our great hero!"

Today's search for this fault is also thanks to President Qin's reminder, otherwise we don't know when to find it. At the same time, if we use separate microcomputers and network operation, the reliability will be greatly improved.

"Let's go, Mr. Qin, have a rest." Colonel Chen said to Qin Guan and left the main control hall with Qin Guan.

When the ship is large, there are many rooms inside. It's like walking through a maze. If you're not familiar with it, it's really possible to get lost.

Now, Qin Guan followed Colonel Chen and went straight to the rest area. He couldn't help sticking out his tongue. The standard double room is the treatment of a five-star hotel!

Think about the narrow space of the destroyer next to you. It's really enjoyable here.
