After a night of detailed discussions, Cao Changjiu officially joined the second research room of the Institute of Computing of the Chinese Academy of Sciences, and the Wang Institute also specially went through a series of procedures for him, specially hired as a research assistant, enjoying 24-level treatment, and receiving a monthly salary of 450 gross hair.

On the issue of this treatment, the king has taken a lot of thought. Cao Changchang is young, has no qualifications, and is simply a black man.

For this reason, Wang Suo specially found General Zhang Aiping. General Zhang is the leader of the 757 project team, coordinating all issues of the project. The king went to the door and lobbied.

When General Zhang heard that he was a descendant of an old soldier, he immediately made a decision, since the project team needs him, he will accept people according to the standard of military children.

And so the matter was settled.

Cao Changjiu didn't care about this level and treatment, his head full of advanced thoughts had no concept of files, ranks, and origins at all, and he didn't think of the benefits that Wang's efforts brought to him.

He just devoted himself to the 757 project, although he often heard that there is such a thing in the world, but it is not easy to create it, even if Cao Changjiu has seen a lot in his dreams, he still doesn't know much about it.

Therefore, under the leadership of Wang, almost all the staff of the project team are developing while studying, soldering circuit boards in the morning, writing programs in the afternoon, and taking time to attend classes in the evening.

Cao has been away from soldering circuit boards for a long time, but he likes to watch it. The circuits of large-scale computers are complex, there are thousands of electronic components, and the heat generation is large, and it is not possible to make a mistake in one of the massive solder joints, let alone the inspection of the desoldering joints under the effect of thermal expansion and cold contraction.

There are many welding masters in the project team, with different styles, but basically they are all like this, holding a soldering iron in one hand and touching the solder joints on the circuit board with one finger in the other.

Cao Chang was amazed, and once tried to master this posture, but unfortunately failed, and left a blister on his finger, so he gave up practicing this skill and concentrated on writing programs.

This is a long-term strength, and the child's heart also wants to show off, but he encounters a problem that cannot be solved physically and physiologically - the hand is too small, and the strength is not big enough.

The mechanical keyboard is a one-click word, and it feels very tactile to press it down, and of course it is also very laborious. Of course, I have been working hard for a long time to compare speed with others, and my little fingers are trembling for a long time. Look at those old programmers, lines of assembly code flow generally come from the fingertips, so easy to read, at the end of the day I don't forget to thank Chang Chang: "This screen display is really good, it's much more comfortable to use." ”

Woohoo, this doesn't seem to be comparable, Cao Changchang's pride collapsed instantly, so he had to follow honestly and learn, thinking that his basic skills were not solid.

The evening class is basically one hour of lectures by Wang, and the second half of the time is for everyone to discuss with each other. Only this time is the most prosperous time for Cao Changchang, and Wang Suo occasionally asks Changchang to come to the stage to talk about the principles of modern compilers and parallel algorithm research.

The people in the project team did not despise the young man for a long time, but they have been working together for a while, and everyone has some understanding of each other. Regardless of whether they are qualified to stand on this podium for a long time, their achievements are obvious to all, whether it is the display system or the multi-user operating system, everyone has admiration.

Needless to say, forget that the multi-user operating system has been ported to the only mainframe computer in the firm. Due to the long-term preparation for porting, the operating system is divided into two parts, the core layer directly uses assembly writing to directly operate the hardware, and the system layer uses the C language, which takes into account both performance and portability, and the core can be rewritten once from the small computer to the mainframe, and all the code does not need to be rewritten.

Otherwise, tens of thousands of lines of assembly code are really a headache, and the conversion of lines is really a terrible thing.

On the mainframe, the long-standing operating system has finally come into play, modified to support up to 40 users at the same time without interfering with each other.

After the new system was installed, Cao Changjiu was still not at ease, and monitored the movement of the system at all times, for fear of collapse. However, according to the people used by the group, it felt so good that it was as if no one had their own console.

Some people even boast that he is a software genius for a long time, and it is said that only Professor Yang Fuqing of Peking University in China has presided over the successful development of a large-scale disk operating system. I didn't think that this guy could be successful, so it can be seen.

These beautiful words made Chang Chang a little fluttery, and finally someone admitted his efforts, and Wang Suo warned him to guard against arrogance and rashness.

The new system is up, and the compiler is also available, all of which are original for a long time. But this is at most a trial, and although everyone feels good, there is no app.

On the one hand, the system is indeed easy to use, but on the other hand, there is nothing in the new environment, so it is an empty shell, and everything has to start again.

Wang Suo once jokingly said: "I don't know if this thing can be raised?"

This just touched a long-term nerve: "I raise what I write by myself, and I will definitely live." ”

However, for a long time, I was still afraid that it would not survive, so I gave the new system a nickname "Dog Leftover". (Loongson hahahahaha)

As soon as the project team members arrived at work, they had to switch to the original system, and all the application software was in the original system, which returned to the old situation when they competed with each other for machines, which made them feel very inconvenient.

Finally, some people couldn't bear it anymore and spontaneously transplanted the software in the original system, or rewrote a new one. "Dog leftovers" finally have application software.

On the one hand, Cao has been vigorously promoting it for a long time, on the other hand, the "dog leftovers" are really easy to use, the new system has really taken root in the computing institute, the application software has been transplanted one after another, and the new software has been written out constantly, almost becoming a general system for computing.

Cao Changjiu, as the initiator, did not make great efforts, and the software was transplanted by others, and it had nothing to do with him. He is now focused on developing new computers with Wang.

The new supercomputer is based on Cray-1, and uses the principles of reverse engineering to simulate its large hardware environment to be compatible, which is very difficult to say.

The Cray-1 computer is a vector structure, which can be said to be the master of today's computing technology, and almost all advanced concepts are applied to it.

Originally, Wang Institute just wanted to learn from its working principle and add its own characteristics to the development. It's a pity that Cray-1 is so advanced for this era that it can't be surpassed with Huaxia's technology.

This is an unavoidable problem, China's industrial base is too far behind the West, not to mention the king, even Cao Changjiu, a person full of advanced ideas, can not be imagined in this environment, and it is difficult for a clever woman to cook without rice.
