Chapter 156

With mom @@'s instructions, long Jianhua had to speed up the construction process of the villa and asked Li Dasheng to start laying log floors. He and his grandparents went to the furniture factory to order furniture.

After finishing all these things, two whole days have passed.

On the 17th, he came to the University of national defense science and technology to find the acquaintance recommended by Mr. Ye... Professor Cai Kailan.

After reading the note written by teacher ye, Professor Cai Kailan glanced at long Jianhua. "Don't you have enough books in the College of Posts and Telecommunications? Do you still come to our school?"

Professor Cai is a very serious man in his forties. He speaks without expression.

Long Jianhua doesn't know whether he was like this or for another reason.

In the heart, he used to write with a note, and he was not formally. He had to make complaints about it by letter.

So he said cautiously, "a lot of school books have been borrowed. In addition, I have something to do when I go home this time. I may stay for a month, but I can't fall behind in my homework, so I have to trouble you."

Cai Kailan stared into his eyes. "I heard that you were specially recruited by teacher Ye. What special talent do you have for him to see, and even don't hesitate to ask someone to let you be recruited?"

Is that the case? Need it be so complicated?

Long Jianhua smiled and didn't know how to respond.

Professor Cai then asked, "I heard you wrote an overview of a synchronous optical fiber network based on optical fiber communication. Can you tell me the main points?"

Long Jianhua suddenly wondered what was going on and how could he know?

"I figured it out after reading some books. As for the specific, I only thought about four aspects. The first is the average optical power of the transmitter coupled into the optical fiber; The second is to reduce the dispersion of the optical fiber... "

Professor Cai waved his hand. "In fact, I am also a student of Mr. Ye, but I was in the early 1960s and can be regarded as your senior brother."

"I wonder why, as a teacher who has always been strict in his style, he specially recruited a high school graduate... From what you said, he has his own set in theory. It seems that the teacher has not been deceived by you."

"I hope you don't just talk on paper, but come up with some research results... Your idea is also an achievement and a very important guiding ideology, which is indispensable for scientific researchers..."

He was there, and long Jianhua was at ease.

It's also Mr. Ye's student. That's the elder martial brother. It's in the same line. No wonder Mr. Ye wrote a few words simply with a note.

It's just that this expression is too serious. Won't it bring some smiles? It's scary.

He was still talking. A man in his forties pushed the door in, saw a man sitting inside and said, "Miss Cai, I'll come to you later."

Elder martial brother Cai interrupted his words and waved to him, "Miss Shao, this is my younger martial brother. Didn't you say you wanted to know who proposed the concept of synchronous optical fiber network? It's him. "

Still expressionless.

Shao Junqi, who wanted to close the door and retreat, pushed the door open again and asked in surprise, "is that him? Isn't it a graduate student of the school of Posts and Telecommunications? "

Elder martial brother Cai nodded, "he came back from something and wanted to read in our library. I took a month's leave before I registered... "

There seems to be some dissatisfaction with this.

Mr. Shao said with a smile, "it's good. You study optical fiber communication and computers..."

He glanced at elder martial brother CAI and immediately changed the topic, "have you considered computers when studying optical fiber communication?"

Long Jianhua shook his head, "No. I've just come into contact with optical fiber communication and haven't considered this yet. "

He's actually depressed.

As long as there is contact with other things in previous lives, it seems that things in memory emerge one after another. There are always some ideas from theory to process to development details; But in terms of computers, I only know a general idea, but I don't seem to have any specific details.

For example, galaxy-i, which their school is studying, only knows that it is composed of mainframe, mass memory, maintenance and diagnosis computer, user computer, power supply system, various external devices and system software.

In addition, Galaxy - I is a vector supercomputer, Galaxy - II is a multiprocessing parallel supercomputer, and Galaxy - III is a large-scale parallel processing supercomputer; Further down, he couldn't think of anything.

Haven't you touched it before? Every day, the computer is already a daily tool, web page, OA, ERP, CAD drawing, word, Excel, etc., which is not necessary?

No, I seem to know a little

"Long Jianhua, long Jianhua?" Elder martial brother Cai's emotionless words came.

"Uh?"

He suddenly woke up and gave a subconscious answer.

Elder martial brother Cai said faintly, "I'm still wandering when talking to elder martial brother?"

Long Jianhua's face turned red, and hurriedly said, "I've just thought of something... About computers."

Mr. Shao said with great interest, "is it very advanced?"

"I don't know whether it's advanced or not. Carnegie Mellon University has successfully developed a shared memory multiprocessor system composed of 16 processors connected with 16 shared memory modules through cross switches, which should increase the operation speed. "

Elder martial brother Cai's body rushed forward, "are you sure?"

Long Jianhua was frightened, but he didn't be frightened by his frightening eyes, but nodded firmly after provoking tigers, catching snakes, fighting wolves and fighting a group of fights.

"Where did you see it?" Elder martial brother Cai still didn't step back, stared into his eyes and said.

It's hard to say. Now he has read too many books and too many periodicals. With the endless things in his memory, he doesn't know where the knowledge comes from.

Shook his head and said, "I don't know. I read too many books, and this is not my focus. "

Shao Junqi said with a smile, "we have only seen such microprocessor information, but you have seen its quantitative composition. Is your information source more efficient than us?"

Long Jianhua felt cold sweat dripping on his back.

There must be something wrong. The information should have been in his memory. He didn't see it in the journal.

A message suddenly came to mind: in the mid-1980s, Caltech successfully connected 64 i8086i8087 processors through hypercube interconnection structure.

Then came another one: in the late 1980s, IBM connected a large number of early RISC microprocessors through butterfly interconnection networks.

Then came another one: in the early 1990s, Stanford University proposed the dash plan, which realizes the cache consistency of distributed shared memory by maintaining a directory structure that stores the location information of each cache block. On this basis, IEEE proposed the standard of cache consistency protocol

A lot of things came out, making his head a little dizzy.

WOW! This is in my memory, not in the journal!

I'm inflated!

I'm not keeping a low profile!

More words make more mistakes. This can't happen again in the future! Don't let others slice!

"Younger martial brother, what's the matter with you, sweating profusely?"

Elder martial brother Cai still has no expression on his face, but his tone has a trace of emotion.

Long Jianhua hurriedly covered his stomach. "Maybe he had a bad stomach for breakfast. Elder martial brother Cai, about the library card...? "

Cai Kailan opened the drawer. "This is a temporary library card. You can only see it inside, not out."

Long Jianhua said thanks to him and fled the office.
