Chapter 776: Alternatives to mainframes

This is exactly the time when it is not picking up.
When it developed into large-scale integrated circuits, Han was quickly lagging behind and was forced to adopt foreign chips. After that, the country began to focus on procurement and completely lost its own research and development capabilities.
The various supercomputers of the later Han State sounded advanced in performance and were at the advanced level in the world. There were several of the top ten supercomputers in Han State.
However, supercomputers like Tianhe-2 still use Intel’s Xeon processors. Following the Eagle Country’s export ban, advanced chips will not be available.
It was not until the birth of the new computer, the Sunway-Taihuzhiguang supercomputer, that 40,960 "Shenwei 26010" many-core processors independently developed by Han Guo were installed. The many-core processors adopted a 64-bit autonomous Shenwei instruction system. The peak performance is 1.25 billion times per second, and the continuous performance is 930 million times per second.
It can be said that the procurement of foreign chips for computer systems began in the late 1970s.
Qin Guan's access point was already too late.
Loongson-1 and Hanxin-1, these advanced microprocessors were all developed in the last two years. Domestic computer institutes have also begun to hope to study supercomputers equipped with these processors, but they have not yet been commercialized. The supercomputer in front of us uses IBM's chips.
Put these aside, this assembly process is really bad, this kind of welding technology, if it fails!
Qin Guan couldn't get it in, watching everyone fix it. This time, from noon to afternoon, from afternoon to night, until three in the middle of the night, finally, the red-eyed Colonel Chen said, "Here, this resistance is soldered! "
The pins of this resistor are surrounded by rosin, and there is usually a little solder in contact with it, but after a long time, the salt corrosion on the sea, coupled with the shaking of the ship, the vibration of the engine, finally made it completely disconnected and appeared Fault. Although it is based on integrated circuits, there are still some discrete components. Any failure of any component may cause overall failure.
"Bring an electric soldering iron!" Colonel Chen personally heated the electric soldering iron and re-soldered the resistor pins. Then, he returned to the top. Sure enough, the fault was eliminated.
"Mr. Qin, you haven't gone to bed yet?" Colonel Chen only noticed Qin Guan who had been observing nearby and asked him.
Qin watched the exhausted technicians and said, "Everyone doesn't find it hard, what else do I have to do, but I feel that our system is not reliable!"
Who knows if there will be any failures when it is needed? The welding level of this computer is not good, and at the same time, it lacks a suitable self-check system.
After all, the previous supercomputers were only used on land, this time in the sea.
Colonel Chen also looked helpless: "Yes, this system does have some problems, but we have no alternative products for the time being."
If you want to carry out aerospace measurement and control, the required computer performance must be particularly advanced. The stronger the computing power, the better.
"What do you think of the computers produced by our Hanxin Technology Company? If needed, we can give priority to our measurement and control boats at any time."
Hearing Qin Guan's words, Colonel Chen continued to shook his head: "Mr. Qin, Hanxin Technology's computer is indeed advanced in performance, but it is still impossible to replace our mainframe computer. Its computing power is simply not enough. "
Can microcomputers do the tasks that mainframes do?
can.
Look at the later generations, except for the supercomputers of national projects, those mainframes, medium-sized computers, etc., have all declined. Due to the rapid development of very large-scale integrated circuits, tens of millions or even hundreds of millions of transistors can gradually be integrated on a chip. The computers that have developed rapidly in the 1980s and after are "microcomputers" and super "microcomputers" used by ordinary individuals. "That is to say, high-performance computers that can form servers or parallel processing, while other kinds of computers cannot compete with microcomputers due to cost-effectiveness issues, so they naturally gradually withdraw from the stage.
The processing power of a microcomputer in later generations is much faster than that of the most advanced mainframe computers today.
To put it simply, take the common I7 processor in later generations, such as i7980XExtreme: 3.33GHz64=79.92GFlops, that is, i7980XExtreme has a peak computing power of 79.92 billion times per second.
The peak computing power of the CPU (how many floating-point operations per second) = CPU frequency × number of CPU cores × number of floating-point computing units.
It can be seen that if you bring an I7 host from later generations, it will be enough to replace so many big guys in the computer room now.
Therefore, in later generations, those manufacturers that still held on to mainframes, and computer companies that did not adjust their strategies in time, such as CDC and Wangan, went bankrupt.
Of course, for now, the processing power of our own computer is not enough, but there are other ways.
"Maybe our single computer has insufficient computing power, but we can connect many computers to perform operations on the Internet." Qin Guan said: "For example, we provide fifty Hanxin computers, which are enough to complete all the tasks of aerospace measurement and control. It just needs to develop special software. At the same time, if these computers are connected to the Internet, there will be surplus. Once one of the computers fails, it will not affect other computers and the entire system can continue to operate."
One is not enough, you can connect to the Internet! Once connected to the Internet, it can fully meet the needs.
In later generations, some people want to perform complex calculations, but they can't borrow super-calculations. The idea is to use other computers on the network to help calculations. If one has insufficient capacity, one thousand, ten thousand?
Now, just fifty Hanxin computers can completely replace this unreliable mainframe.
Hearing Qin Guan's words, Colonel Chen thought: "Yes, I'm going back this time. We can try it. If it succeeds, then you will be our hero!"
Today we are looking for this failure thanks to Mr. Qin’s reminder, otherwise we don’t know when to find it. At the same time, if we use a separate microcomputer and networked operation, the reliability will be greatly improved.
"Let's go, President Qin, let's rest." Colonel Chen said to Qin Guan, and left the main control hall with Qin Guan.
After the ship is big, there are more rooms inside, like walking through a maze. If you are not familiar with it, you may get lost.
Now, Qin Guan followed Colonel Chen and went straight to the rest area, and he couldn't help but stick his tongue out. The standard double room was simply the treatment of a five-star hotel!
Think about the small space of the destroyer next to it. I really enjoyed it here.
