A cluster system is a collection of multiple computers connected to each other, these computers can be single or multi-processor systems, each node system has its own independent set of processors, memory, input and output interfaces and operating systems, relying on the main processing system to allocate tasks and rationalize the use of resources.

Although the fleet is composed of several computers, it is a single system for user applications, which is completely indistinguishable from a single machine, which can provide a cheap and efficient computer environment and a convenient operating environment.

Of course, it is impossible to achieve a general-purpose fleet with the power of the 021 processor, and what can be done at present can only be optimized for statistical work and obtain relatively high processing power.

All this requires operating system support and some hardware changes, which is definitely perfect for solving the problems we are facing for a long time.

I'm really glad I didn't take out the DOS operating system recklessly at that time, otherwise it would be a big trouble. I started with the mainframe and wrote the operating system that naturally took UNIX as the first choice, and I didn't expect it to be used here.

To build a machine group, it is necessary to have high-speed computers, high-speed networks, etc., and most importantly, the support of distributed shared storage. The high-speed network is a headache, but for a long time, it has learned from the experience in the development of switches and introduced the ring token system, but the network transmission speed still can't keep up.

However, speed is important, but the road must be wide, so the technology of the 757 mainframe has been directly used for a long time, and the distributed shared storage system is used to solve the problem of bandwidth.

Fleets have demanding operating systems that must support multi-user and multi-tasking, as well as strong network capabilities, and long-written operating systems are a natural match, at least without having to start from scratch and modify them. In order to be able to support the fleet, a strong network protocol has been added for a long time, regardless of the general, directly optimized for the purpose of this system, ensuring the speed of the machine.

As for the soul concept of the machine group - parallel computing, this is a long-term strength, as early as the time of the computing institute, he has spent a lot of energy on the optimization of parallel compilers, and then the multi-processor workstation came out, and it is really a matter of course.

For this bidding, the General Administration of Computer specially opened the back door for Changjiu, and united 12 domestic microcomputer manufacturers and research institutions to carry out the bidding machine sampling work, and served as a consultant for a long time.

Fortunately, this thing is not too complicated, and I have a long experience in the design of 757 large parallel machines, and I quickly came up with a design plan, and the following is to build the building blocks.

The operating system is more troublesome, and after a long time, I took out the dusty source code of the operating system and began to add various required modules. The code is relatively cool, thanks to the modular design that has been adhered to in the early days for a long time, although it takes up more resources, but it is maintainable, and there is no need to rewrite it like now, otherwise it will move the whole body, and the workload will be large.

Moreover, the storage system of the fleet system is larger, and they do not need to shrink back to compress the code for a long time, although it is a little rougher, but the speed is guaranteed, otherwise it will be troublesome if they can't catch up with the construction period.

There are more than a dozen programmers at the disposal of the long-term hands, all of whom are researchers in various factories, with extremely high professional quality, and they are relieved to divide a few tasks for a long time, and the system is done by themselves for a long time, as for all kinds of application software for statistics, they do it on their behalf, there is only one principle, not to streamline as long as the construction period is guaranteed.

Two months is not short, it is not long, anyway, it is not a long feeling, he is used to it, before he gets married, there is no more comfortable job than writing a program.

It's just that sometimes he can't tell for a long time whether it's the joy of programming or the game that attracts him, his original intention was to be able to play the game as soon as possible, and now it seems that he has played big, and he actually played something else.

Just when the design of the machine group was completed for a long time, there was good news from Shenzhen, the research room Wanmen Bureau with program-controlled switch was successfully launched, all the performance under the simulation test fully reached the standard, equivalent to 8000 door user models, there is no similar type of product in China, and only a few foreign manufacturers can provide this kind of machine.

The news is very good, and he is naturally happy for a long time, but he also knows that this is just the beginning, and if he is not careful, he can lose all his efforts. Therefore, he made a special trip back to Shenzhen to see the successfully developed machine.

This machine covers an area of about 100 square meters, composed of various cabinets, and the related wiring is dense, but it is very neat and looks a little high-tech.

"Have you been connected to the grid for a test?" asked Chang Chang, looking at the flashing small lights, with a sense of accomplishment.

"No, it was just a simulated user trial. Zhang Yi replied, she has been absent for a long time, and she is now taking over the coordination of the research room, "Without your nod, how dare we, hehe." ”

"It's better not to move for the time being, you are familiar with it, and inquire about the procedures that you have to go through if you want to sell this thing to the state. "I have vaguely remembered for a long time that it is very cumbersome for domestic products to access the network, and it is easy for foreigners to get a network access license," to keep it secret and ensure suddenness, it should be out of some blood. ”

"I'll do this, and you can concentrate on your business. Zhang Yi is very strange, this half-sized technical pimple actually has these tricks.

"I don't like that, but that doesn't mean I don't understand, and I don't want to be a victim of reform. "By the way, the switch has only been successfully developed, and there is still a long way to go, and there is still a long way to go, and there is still a long way to go from industrial production." The first goal is to test the machine and make sure it is stable, the second is to find out its shortcomings and make a table for next improvement, and the third is ......"

I thought for a long time: "I want to industrialize!"

"Industrialization?" Zhang Yi was a little stunned, "Now the customers are not industrialized?"

"The customer is the country, put there will not run, from now on to find a site to build a production line, if the time is tight, you can also find manufacturers to cooperate, the supply must be smooth. "I attach too much importance to this for a long time, and the switch without industrialization is just a symbol, and all the research and development results can only be spent in the warehouse for the rest of my life.

Although Zhang Yi was reluctant and had a lot of complaints in her heart, she was very interested in not questioning the meaning of the long term in front of the public, and she did not speak out.

In her opinion, preparing for industrialization without market research at all is tantamount to jumping off a cliff to find the secret, where does she know that this guy knows where the secret is.

At this time, all the members of the research room were on the scene, waiting for a long speech.

A R&D backbone couldn't help it and asked for a long time: "Mr. Cao, how is it, is it done?" ”

"It's done!" he smiled for a long time, "Everyone has worked hard in the past two years, I invite everyone to eat seafood!"

Suddenly, there was thunder in the laboratory, and some people even shed tears. Only they know the hard work of the past two years, and their former friends even ridiculed them for not doing their jobs properly, and the dignified state scientific and technological personnel who used to study computers are now engaged in such nondescript things, and they really can't raise their heads.

"Everyone's performance is in my eyes, suffering and sharing happiness. He continued to speak loudly for a long time, "The successful research of this program-controlled switch is considered to be a stage, I Cao someone has spoken and counted, and I have endured hardships, and now it is time to reward meritorious deeds, and I will count them later, and give you a bonus for successful development." ”

Everyone suddenly stopped making noise and began to whisper, discussing what this successful development bonus was and how much money it could have.

He also wanted to surprise these people, calm their hearts, and let them put down their roots in the research room.

In the past two years, R&D and life have been together, and they have an understanding of their ability for a long time, these people are definitely worth retaining, a team does not need many people, the key is to have cohesion, and it is unstoppable after forming.

A week later, Changchang finally gave everyone a bonus according to his promise, not according to rank, not according to age, only about contribution. The basic award is 10,000 RMB, everyone has a share, and the others are scored according to their role in R&D.

These are all well documented, because when the research laboratory was established, Zhang Yi formulated detailed rules on rewards and punishments, and implemented a point system, no matter who he did, as long as he did one thing, he could get the corresponding points, and finally summarized and converted into a ten-point system, which was used as the standard for bonus distribution.

This is still a long-term idea, the research room was created, there is no corresponding system in China, the shares are not yet talked about, all are long-term own funds, in order to integrate the team, we have to reward and punish clearly, so this idea was proposed.

This is fair, and eating by ability makes these scientific and technological personnel full of enthusiasm for work, and they almost compare with each other to improve their points.

Zhang Yi did not object, she is considered a management team, she gets an annual salary, and she is not paid for a long time, the salary is directly received from Hong Kong, and the research office here is only responsible for coordinating and handling daily affairs, and the work is relatively leisurely.

The amount is relatively huge, and all bonuses are issued to R&D personnel in the form of passbooks. The passbook is just a piece of hard paper, but the team members hold it like a treasure, look at it over and over again, count it dozens of times, and the number on it still seems to be five, which makes them feel uneasy. They can't believe their eyes, they don't know if something is wrong, and they don't dare to ask each other, because God knows how many others are?

Some honest ones asked for a long time to ask about it, whether the bonus was wrong.

Chang Ze said with a smile: "This is what you deserve, you must get something for your efforts, otherwise what else will you do." ”

For a while, everyone was extremely grateful, and they simply threw themselves on the five-body body that this leader who was less than 20 years old, and didn't know what to say. Don't want everyone to say anything for a long time, he wants this effect.

However, for a long time, I specially told everyone to make a fortune in a muffled voice, don't publicize it everywhere, and the research room will not treat everyone badly.

This person understands that no one wants to ask for unnecessary trouble, and in this era when you can build a house for a few hundred dollars, it is better to keep a low profile.

The first stage was a success, and the long-term announcement of a week's holiday, seven days later, was still gathered at the post, and there were new challenges waiting for everyone.

With the bottom of the wallet, everyone's voice of promise is extraordinarily simple, and they have expressed that they are not afraid of hardship or tiredness, and they can take it with a raise their hand if there is any difficulty.

I was very satisfied with the morale of the team for a long time, and I was relieved to let Zhang Yi prepare for the appraisal of the results and access to the network, and he flew directly to Beijing to find the leaders of the General Administration to see how the bidding was going.

Sweat, everything is not ready, and the industrial base is so poor, so I have to bite the bullet and let the group be on the plane for a long time, and I feel very sorry for the audience. Comfort yourself, YY, fortunately, it's only a special machine for statistics, otherwise I really can't explain the gap between 8 bits and 16 bits.
