In the end, Cao Changjiu proposed a stupid solution, Cray-1 is advanced, the process is very fine, and the technical level of Huaxia is indeed unable to catch up with the Americans.

But Cray-1 is a single-vector array with a multi-peripheral processing structure, which means that the Americans use a single processing unit to calculate all the problems. But what if you use two or more?

Based on the principle that two is greater than one, Cao Changjiu proposed the architecture of the dual-array vector processor, while expanding the bandwidth of input and output, and supporting multiple scalar processors to balance the amount of calculation, and strive to make the whole machine without the existence of bottlenecks, and its main central idea is to let the data flow up without interruption.

As a result, the difficulty of development increases exponentially. Almost no one has ever made this type of machine in China, and it is rarely heard of abroad.

Naturally, the development team was divided into two groups, one group was more important, believing that it was difficult and risky to develop multiple processors in parallel, and that the 757 should follow the mature technology and completely "clone" Cray-1. Their reason is that how can Huaxia do it with advanced technology that is not even used by the Americans.

On the other side, there are a few radicals, who believe that we are much behind the Americans in terms of manufacturing technology and design ideas, and that we are behind the ass of others, and do not dare to take a step beyond the thunder pool, at most it is an imitation. We can't make as much as others, but we can make up for it with advanced design ideas.

The two factions debated each other, and no one could convince anyone. Wang Suo, on the other hand, pondered the difficulty of the two schemes.

There was a mess in the project team, and Cao Changjiu couldn't help it, the direction of the 757 project has been endless for a long time, and it is really not humanly controllable.

Wang itself is inclined to improve the structure of the 013 machine to achieve the goal of 100 million times per second. However, the higher-level requirements are to be compatible with the Americans and the vector structure of Cray-1, which is tantamount to completely negating the previous research results of the project team on large-scale computers. Therefore the king could not make up his mind.

On the one hand, Cao has long understood the direction of the development of computer technology in the next 20 years, and large-scale computers are destined to be occupied by vector machines, and the country is indeed doing the right thing in this regard, and at least it will not make a mistake to follow the Americans closely.

On the other hand, there is a sense of resentment in everyone's hearts, and the mood of expecting Huaxia to surpass cannot be extinguished. And Chang also knows that parallel multi-processor technology is king, whether it is vector machine or other types, there is no escaping this topic, someone has to do it. But there are very few people who support his view.

Mature and sure to succeed technology and new technology that has the potential to surpass but have no precedent compete with each other, and eventually it still makes trouble at the top.

Without any suspense, the upper management finally chose a steady research direction and resolutely took the path of compatibility with Cray, but allowed the project team to conduct preliminary research on parallel multi-processing technology.

In other words, it is still the traditionalists who have the upper hand, and Cao Changjiu is already thankful for this.

Since Cao Changjiu agreed to join the project team, he has really put himself and the national supercomputer project in the first place, no matter whether he can or not, he must always develop what he thinks is the most advanced technology, and this conflict between the traditional and radical factions is caused by Cao Changjiu and several people who are influenced by him.

Cao Changjiu really made a few young friends during his time in the computing institute, all of whom were hot-blooded young men, and everyone was reprimanded by Wang Suo, saying that everyone was not united, and finally made everyone lose face.

However, after the above instructions came down, everyone was relieved, no matter what they did, as long as they had a direction, otherwise they would definitely not be a complete team.

Although Cao Changjiu was not convinced, he had to obey the order.

Wang Suo also felt sorry for them, although he also vaguely saw the prospect of parallel multi-processing, but as the commander-in-chief of the entire project team, he still had to start from the whole, and it was his first choice to avoid risks and solutions.

After the turmoil came to an end, the project team held several more meetings and began to unify their thinking and make every effort to carry out research and development work.

But Wang Suo still gave Cao Changjiu and the others the green light, allowing them to study parallel technology while completing their own tasks.

Cao Changjiu and his like-minded colleagues were extremely depressed, and they simply did not have many tasks for the project team, and they had plenty of time to complete their work.

After discussing it, the brothers generally determined the direction of parallel research, and started their own work.

Several of them are now using the 757 prototype of the project team's research results to write a simulator to simulate the processing of data by a multiprocessor system, which is running on the 013 machine.

Statistically, the results are satisfactory, not very outstanding, but also decent, with 20% more efficient than a single-processor system, up to 35%.

However, there are still flaws, because the parallel algorithm is rough, which sometimes makes the computational efficiency lower than that of a single processor.

Although Cao Changjiu and others have a lot of confidence in the multiprocessor system, it only takes time to solve the problem of the algorithm, but what they lack most now is time.

Nearly 5 months have passed since their research reached this point, and the progress of the entire project team has entered the stage of prototype assembly, and the project is very busy.

The enthusiasm of several people has almost worn off, and the parallel research work has basically come to a standstill.

Cao Changchang was also a little discouraged, so he simply gave up this aspect of action and concentrated on his own work first.

It's been 78 years now, and Cao Changjiu couldn't help but sigh when he looked at the blue sky. What a blue sky, it seems that I have lived for decades longer than others, how come I have never noticed such a blue sky.

I wanted to change the world with my knowledge, but I didn't expect that my own power was insignificant, and I didn't even have the ability to cause a ripple, which is really sad.

I wonder what the competitors across the ocean are doing right now? Jobs and Woz's Apple II are already on sale, and they should soon be millionaires.

Bill Gate is probably still perfecting his Basic language, and this guy born with a golden key must be planning how to conquer the software market.

Dell should be selling his stamps by now, and probably almost buying his BMW sports car.

Cao Changjiu smiled bitterly, well, the harvest is not small, at least there are not too many people in the world who develop supercomputers, and he is one of them.

Cao Changchang is still grateful to Wang Suo in his heart, after all, he let himself enter this field, and he didn't dare to imagine it before.

I have been here for almost half a year, and Cao Changchang has obviously learned a lot of things that he does not have in theory. Supercomputers are the frontier of science and technology in any era, and there is no shortcut to all technologies, only the accumulation of step by step.

After more than half a year of tempering, Cao Changjiu also put away his pride, worked hard to learn from others to make up for his own shortcomings, and at the same time worked hard to realize the advanced concepts he knew. But manpower is sometimes poor, and except for software, Cao Changjiu has not yet achieved any recognized results.

The assembly of the prototype is imminent, but the development progress of domestic components is seriously lagging behind.

But this kind of big project is also the cooperation of the whole country, a link can not keep up with the whole system, Wang is the commander-in-chief, but there is no way to do this, so I have to go to the factory one by one.

Cao Changchang's work had already been completed, and he volunteered to go to the semiconductor factory with Wang to inspect the progress. He has long been interested in chip manufacturing, but he didn't have the opportunity. In his dream, he had dealt with chip manufacturing companies, but the only opportunity to visit was missed because of a trivial matter.

At that time, he followed the foreign boss to inspect a foreign chip manufacturing factory, and after some exchanges, he was finally going to visit the factory, and Cao Changchang was ready to change clothes with great interest.

Who knew that the person in charge of the chip factory inadvertently asked what you had for lunch?

The foreign boss replied that he ate seafood.

Cao Changjiu still clearly remembers how the person in charge of that dog day refused them, the reason was that they were not allowed to eat fish and shrimp when they entered the workshop!

Cao Chang was puzzled, and later heard them explain that fish and shrimp contain a lot of phosphorus, and the gas exhaled after eating will pollute the air in the workshop.

And the most taboo in chip manufacturing is this, once someone eats fish and shrimp into the workshop, the workshop will be inexplicably scrapped for a few weeks.

The person in charge at that time refused Cao Changjiu's request to visit with righteousness and solemnity, and let Cao Changjiu beg him with a smiling face, his expression seemed to owe others more than 100,000 yuan, and Cao Changjiu, who saw it, wanted to smoke him. In the end, the person in charge just gave Cao Changchang a scrapped chip and it was over.

Unexpectedly, this crossing will have the opportunity to contact the core manufacturing industry of the electronics industry, or Huaxia's own, Cao Changjiu is really not looking forward to it.

Who knew that this small opportunity became the beginning of Cao Changchang's entire life legend.

～～～～～～～～～

The fish is bubbling: the campus, the almost eternal YY topic, the fish also knows that letting it go in for a long time can produce many jokes and attract the attention of many readers.

But the fish is very confused, a stupid B with adult memories has crossed over, will he choose to go to school, let alone that era (77 years before starting to re-take the college entrance examination)? If it were me, it would definitely not, because there was a more free choice. Just like Xu Gongzi, who fish likes, said, a monkey has become a sperm, can speak human words and become human, will he return to the monkey group to be the monkey king?

As for human affection, it's my weakness, I don't know how to write to be good, and I'm very distressed, so I directly let this guy have no father and no mother, and he is still an autistic person who is cured. Let's change it slowly in the future. ^_^

Maybe it's because the fish's head is a little stiff, I don't like the campus, I hate stallions, punch romance and kick cheats, I'm too lazy to write the setting, in short, I'm full of problems. The fish just wanted to write a little bit of a real, possibly powerhouse YY article. Pray for God's blessing, so that the more the fish writes, the smoother the writing becomes, and the article is no longer as hard as iron as Mao Lao said, and the mouth is full of blood, and it is content!
