The Red Era, the Opening University Speech

Chapter 254 Isn't that a coincidence? I just optimized the plan
"The architecture we used before was mainly homogeneous parallel computing, but I have a better idea, which is heterogeneous parallel computing."

"In my vision, heterogeneous computing can take advantage of different computing units, such as CPU, GPU, DSP (signal processor), and other different computing units to improve the overall performance and efficiency of the system through parallel and distributed computing."

"So, how do we implement heterogeneous parallel computing? This involves three key steps: chip-level integration, board-level integration, and system-level integration. Let me explain in detail how to implement them..."

……

Heterogeneous computing can significantly improve processing speed and reduce power consumption by assigning different computing tasks to the most suitable computing units.

This technology is the product of the third stage of supercomputing development and has considerable advantages over homogeneous parallel computing.

If it can be developed, there will be no architectural problems in Xiaguo's supercomputer research for at least ten to twenty years.

……

Let’s talk about the processor architecture.

Li Mu continued to talk with Professor Bai and Professor Zhang, the leaders of the storage system development and software and algorithm optimization groups, about their research directions.

The first is the storage system of the supercomputer. We need to deal with the memory used for temporary storage of data and persistence in the system - static random access memory (SRAM) and dynamic random access memory (DRAM).

SRAM is much more expensive than DRAM, but is also faster and is usually used as cache, while the latter is generally used in main memory, that is, RAM.

We have already gained considerable experience in the research of the two types of memory in the first generation of supercomputers, but this is far from enough.

How to increase their capacity is the next challenge they need to overcome.

The Red Sky supercomputer, which later ranked among the top ten in the world, was equipped with a large amount of 64TB random access memory, proving that they have broad research prospects and will not be easily eliminated.

Then there is the software and algorithm optimization group.

Software upgrades mainly include system upgrades and application upgrades.

In terms of software, the main focus is on developing software that can fully utilize the huge computing power of the second-generation supercomputers without wasting computing resources.

In terms of algorithms, the main research is parallel computing, distributed computing, grid computing and cluster computing, etc. However, unlike the processor development group, the former focuses on computing technology and methods, while the latter focuses on the optimization of hardware architecture.

……

By the time Li Mu and the three groups had finished explaining their plans, it was already dark.

After a day of intensive lectures, his mouth was inevitably dry. He picked up the enamel cup beside him and was about to drink some water, only to find that the water in it had already been drunk.

I looked at the time and it was already 6 o'clock.

Just as he was about to finish his meal and go to the lab to work late, he saw Wu Youxiang staggering over and saying:
"President Guo just called me. You need to have a good rest these few days. Have dinner later and go back early."

"The resumption of the National Highest Science and Technology Progress Award is not only a major event for our scientific community, but also has a significant impact on all sectors of society."

"By then, there will definitely be a lot of reporters heading to the scene to interview and report. You can't let them down at this critical moment!"

Hearing his words, Li Mu's face turned bitter. Asking him to go back now would be like asking for his life.

"Director, it's only 6 o'clock now. Even if you ask me to go back, I can't sleep!" Li Mu couldn't help but remind him.

Wu Youxiang glared and said, "You have to sleep even if you can't. Anyway, you can't stay in the station."

Seeing his serious look, Li Mu had no choice but to nod and agree.

……

After dinner, Li Mu originally wanted to see if there was any chance to sneak in, but when he got downstairs, he saw Wu Youxiang guarding there like a door god.

After thinking about it, after today's meeting, everyone will need some time to digest the content.

In addition, new researchers need time to adapt, so there is no need to give them full intensity right from the start.

After looking at the direction of the laboratory reluctantly, Li Mu finally had no choice but to return home.

……

After returning home and putting down his briefcase, Li Mu lay on the sofa to rest for a while, then got up and went to the study to continue his research.

The problems with the supercomputer can be put aside for now. After digesting them tonight, we can solve them if there are any problems tomorrow.

Regarding the research of the semiconductor group, they have been reporting on the progress from time to time since the last conference.

The development of the heating coil is actually very simple. It is based on the principle of heating by electric current flowing through a resistance wire. A thinner metal tube is wound into a heating coil, and an electric heating wire is installed inside.

The more difficult part is how to ensure its safety. It is necessary to design a device that can immediately cut off the power supply when the water temperature rises to the boiling point.

But Li Mu doesn't need to worry too much about this, as the experts and professors of the Semiconductor Group are not so poor that they can't even make a constant-temperature bimetallic temperature controller.

What he needs to pay attention to is the development of laser printers and plotters.

A laser printer is mainly composed of a laser, an acousto-optic modulator, a high-frequency driver, a scanner, a synchronizer and a light deflector. Its principle is to modulate the binary dot matrix information sent by the interface circuit onto the laser beam and then scan it onto the photosensitive body.

The most core component is the laser, which is responsible for generating the laser beam. After a series of reflections and focusing, it finally irradiates the imaging drum, directly affecting the quality and speed of printing.

The laser is mainly composed of a laser tube, a reflector and a power supply, among which the laser tube is the most important component.

Its optical working principle is that when current flows through the gas, the gas discharges and generates photons. During the continuous excitation process, a large number of photons collide repeatedly inside the lens barrel and are then forcibly sniped to form a high-energy, high-brightness laser beam...

……

After analyzing the entire production process of the laser printer in detail, Li Mu put down the pen in his hand, leaned back in his chair and let out a long breath.

The Semiconductor Group is different from the Semiconductor Research Institute in that its purpose is very clear, which is to make profits.

It has been a long time since they released a new product since their last product, the video game console, which is obviously not good news.

"I can't let this award down!" When Li Mu thought about the fact that his superiors were going to award him the National Highest Science and Technology Progress Award, he sat up again as if his whole body was injected with chicken blood.

Just as I was about to continue my research, suddenly, a "ding~" message alert sounded in my mind.

Li Mu raised his hand and looked at the watch on his wrist. It was just a little past 9 o'clock, so it would be okay to chat with Ask.

Open the chat page.

Ask:
"Li, thanks to your help, I got through today safely!"

"Although she bought me a lot of things, I sold them back at the same price."

"Now, even if we break up in the future, I won't have to bear the stigma of being a scumbag."

Without waiting for Li Mu to ask, Ask told him everything that happened during the date.

"Good, keep it up. By the way, don't just focus on romance and neglect your studies." After listening to it, Li Mu was secretly happy in his heart, but he did not forget to remind her.

What if, while helping, Ask suddenly realized the good of the little rich woman, stopped studying, bought an island and traveled around the world, and he had no place to cry. Ask: "Don't worry, studying is the first priority in my heart!"

……

After chatting with Ask for a while and teaching him a few tricks to make a relationship fail, Li Mu returned to his research.

It was still early, and he had to continue with the detailed disassembly of the plotter to ensure that the product department of the semiconductor group could produce results as soon as possible.

He was busy until about 12 o'clock, when Wang Ya reminded him to take a break.

He originally planned to stay up until 2 o'clock before going to bed, but after thinking about what Wu Youxiang said during the day, he felt that there was some truth in it.

The award ceremony for the National Highest Science and Technology Progress Award is a huge occasion with many media reporters present. If he stays up all night for several days and falls down because he doesn't step firmly, he will be laughed at for more than ten years.

……

The next day, I washed up and exercised.

Came to the First Ministry of Machine Building.

Led by the secretary, Li Mu came to Leader Qiu's office.

The former knocked on the door twice. Leader Qiu, with a worried look on his face, raised his head and saw that it was Li Mu, his brows relaxed a lot instantly.

The secretary was about to make tea, but he waved his hand and called her down, and he personally made tea for Li Mu.

As he poured the water, he said, "Speaking of the devil, he appears. I was just thinking of looking for you to solve the problem, and here you are."

"Oh, let me guess, is there a problem with the development of laser printers and plotters?" Li Mu asked with a smile.

Leader Qiu put down the tea and sighed, "That's right. Since the conference, the researchers in our group's product department have been studying the plan you gave them for a long time, but there has been little progress!"

It's no wonder that he sighed. When Li Mu was helping him in the past, the speed at which he produced products was as fast as riding a rocket. As soon as one product came out, the next one was already under development.

But this time, these three are getting hot and making good progress, but there is no technical content.

As for laser printers and plotters, even with plans and complete solutions, most people in the product department were completely in the dark and could only learn and advance slowly.

This is certainly feasible for technical research, but this is product development.

Especially the higher-ups felt that if Li Mu could do it so fast alone, if they worked as a group, they would at least be half as fast, if not the same.

However, the actual situation is that, let alone half, it is not even one tenth!
Li Mu saw this and smiled, "Isn't that a coincidence? I just happened to have some free time last night, so I optimized the previous plan again and wrote down all the feasible experimental methods."

As he spoke, he took out two supplementary plans that he had written last night from his briefcase.

Seeing the thick stack of manuscript paper, Leader Qiu was immediately overjoyed. He quickly took it and called his secretary without thinking, asking someone to send the information directly to the product department of the semiconductor group.

After doing all this, he turned around and looked at Li Mu and said, "I was wrong just now. You are not Cao Cao, but timely rain. You solved a big problem for me as soon as you came!"

"I'm just trying my best." Li Mu smiled slightly. He knew that if he didn't stop him, he would have to listen to the other party's praise again. He quickly asked, "By the way, how is the game department? Have they developed any good games?"

"Although the price of game cartridges is low, they actually account for the bulk of the profits."

He hasn't been to the game development center for a long time, but he guessed that they should have made a game.

"Mr. Yan brought the latest game cartridge the day before yesterday, called 'Sniper Three Virtues'. I was just planning to ask someone to send it to you." Leader Qiu sat on the sofa, visibly more relaxed.

Sure enough, I still have to rely on Li Mu.

Although everyone's research has made some progress, compared to Li Mu's speed, there is a huge gap.

Hearing this, Li Mu said, "I know about Sniper Sande. It was developed by the group of students at the Beijing Institute of Technology Game Development Center under my guidance. I am also confident about the entire game."

"If we sell it, I'm not sure if it will be a big hit, but it should bring in a lot of money."

"Okay, then I'll take it directly to the factory below and have them start production immediately." Leader Qiu said without thinking.

When he heard that Li Mu was involved, he knew that it was a safe bet.

This reaction made Li Mu feel a little amused and helpless. It is a good thing to gain the trust of the leader, but sometimes it is inevitable that people feel a little stressed.

He quickly said, "I'd better take a look. I haven't been there for a while. Maybe they have added something new."

"This is their first work, so they should be more cautious."

"With this success, I believe they will become the backbone of our game department's game development talents in the future."

"You've thought it through carefully. Let's do as you say." Leader Qiu thought about it and agreed.

He doesn't understand game development, but he understands Li Mu.

No matter what Li Mu says, he will not interfere as long as it is related to the semiconductor industry.

……

Didn't sit for too long.

After drinking a cup of tea and having a pack of Dahongpao stuffed into his hand, Li Mu left under the smiling gaze of Leader Qiu.

Instead of rushing to the institute, he rode his bicycle to the Ministry of Culture and Education to check the progress of the compilation of the software engineering textbooks.

As soon as he arrived, he saw several old acquaintances from the Institute of Computing Technology and greeted them with a smile: "Professor Xia, Professor Sun, Professor He, hello!"

"It's Consultant Li. Long time no see." The three of them turned around and greeted him enthusiastically. They walked upstairs while reminiscing about the past.

Li Mu asked curiously, "Why are you three here at the Ministry of Culture and Education? Aren't you busy with research at the institute?"

It's no wonder that he was curious. After the Semiconductor Research Institute's supercomputing project held a meeting yesterday, Wu Youxiang must have immediately submitted a request for joint research.

Although the entire Semiconductor Research Institute will not be drained of its personnel this time, at least three professors who have made great achievements in the field of computing technology and have participated in the development of the first generation of supercomputers will not be allowed to hang around here.

Professor Xia saw through Li Mu's thoughts at a glance and said unhappily:

"You, you, we three are already old, why do you always want to order us around?"

"Don't think that only your Semiconductor Research Institute has added research manpower. Our Computing Technology Research Institute has also added a lot of manpower since the last supercomputing success to prepare for emergencies."

"The director said that the future belongs to you young people. We old bones just need to protect you."

After he finished speaking, Professor Sun and Professor He beside him looked inside with mockery in their eyes.

It is a bit of an exaggeration to say that Li Mu Lao wanted to order them around.

But it was true that Li Mu wanted to keep all the people in their Institute of Computing Technology in the Institute of Semiconductors. After the success of the last supercomputer research, many people stayed in the Institute of Semiconductors after being "persuaded" by him.
