Chapter 646: Diamond Computer?

When he did not become President Nan and was just an ordinary person who paid attention to technological developments, Nanming was still very proud of Tianhe-2's consecutive top spot.

But after entering the supercomputing pit and developing the Qingda Lazy God, Nan Ming knew more about supercomputing, and felt a little sorry for Tianhe-2.

Tianhe-2 is rarely able to run at full capacity. So far, there is no calculation item that can make Tianhe-2 fully display its strength. This feeling is like a peerless swordsman who has achieved peerless martial arts, but can only compete with It's like the villagers are fighting in groups.

This made Nan Ming of the Practical Party deeply regretful.

Nanming sincerely believes that it is more important to let the current Tianhe-2 run at full capacity first, to truly take advantage of the advantages of supercomputing, and to accumulate experience in making supercomputing run at full capacity.

Because next, changes are about to occur, which will reshape the entire computer science community.

This change is not due to others, but Lazy Technology.

The discussion between Nanming and Lanshen Technology just now, although there is still no conclusion, but the basic idea has been determined.

That is the beginning of the lazy god system to officially enter the chip industry.

But the glass heart that suddenly appeared made Nan Ming suddenly realize that he seemed to be acting a little too enthusiastic, even a little burdened with shaving his head, and his head became hot.

Nan Ming was born generous and willing to help others. Because of Lao Bai's relationship, Nan Ming regarded Bai Songtang as his own, and did not shy away from the people around Bai Songtang, but at this moment, people may not necessarily regard him as their own.

After being satirized by the words, Nan Ming suddenly laughed.

Talk lightly and deeply, why bother to confide in the heart, since people are doing business, then treat it with a business-like attitude, there is no need to make any small fuss.

Then he let go of Bai Songtang's hand, and said, "Look at me, I'm just talking to you guys, how about this, I'll introduce one of our supercomputing experts, you guys have a chat."

Nanming directly ordered: "Dabai, call Professor Liu Nanchuan Liu."

Dabai let out a beep, which was regarded as feedback to Nanming's order.

"Professor Liu Nanchuan is a master of our computer department at Qingyang University. He is very researched on supercomputing. He has published a few papers recently. I believe you have read them. You can communicate with Professor Liu Nanchuan later. I still have a little There are other things to deal with."

As Nan Ming said, he stretched out his hand to see off the guests.

Professor Liu Nanchuan arrived soon. Although he was a little confused, he still warmly greeted several people.

He was led out of Nan Ming's office in a daze, Bai Songtang frowned and didn't know what he was thinking, the person behind him said with satisfaction: "That's right, a kid who doesn't understand anything, messing around What are you talking about... What does he know about the super-computing competition!"

No matter when, Nan Ming's age is a fatal injury, especially for people who came out of places where the seniority is relatively serious. Of course, they have seen a lot of people who have skyrocketed because of their talents and abilities, but most of the mediocre people are ranked Stand in line and wait for the fruit.

As a mediocre person, I naturally feel that others are mediocre.

Bai Songtang wanted to say a few words about him, but he was only the team leader, not the leader. Thinking of this person's identity and the supporters behind him, he just shook his head.

Lao Bai stood aside with a wry smile, seeing Liu Nanchuan chatting with a few people, there was no barrier.

Liu Nanchuan is one of the masters in the School of Computer Science of Qingyang University. He taught Nan Ming and his class the database principles. The inflated Qingda Lanshen almost turned Qingyang University's supercomputing research institute into the supercomputing operation and maintenance department of Lanshen Technology, and Qingyang University's School of Computer Science and Technology as a cheap labor market.

A group of hard-working graduate students acted as cheap labor, followed their teachers, and became free laborers, busy every day to expand, expand, and expand the capacity of Qingda Lazy God.

But the process is not without rewards.

Ultrasound is a kind of engineering, and the experience brought by practical operation is precious, even sometimes more precious than theory.

In the actual process of dealing with various problems and failures, Liu Nanchuan learned a lot of advanced knowledge from his former students and his current bosses Su Hongyi and Han Dong. Other than the two of them, the strongest technical experts can be the opening or closing guests of the grand finale even if they go out to attend a meeting. Nanming did not lose the price by calling Liu Nanchuan to receive them.

This is still for Bai Songtang's sake.

For Liu Nanchuan, this period of time was a period of rapid growth. Liu Nanchuan even felt that after a year or two like this, he would be able to establish a sect and write a book.

And those doctoral and master's students who are regarded as cheap labor have also made rapid progress one by one. Some time ago, even a master's degree published a paper with great influence, which aroused wide acclaim.

And this kind of improvement is almost average, not one or two, but tens or hundreds.

This is almost a qualitative leap for the Qingda Institute of Economics and Information Technology, which was almost transparent before.

As for Liu Nanchuan, who is close to the water, he can put down his airs and has a very correct attitude. He consciously helps Su Hongyi and Han Dong. To be honest, even the core code of Qingda Lazy God has been exposed to a lot. The task distribution system, he contributed a little bit of code to the Doudou program. Although his talent is not as good as the "Gods" of the lazy gods who have been strengthened by various books, it is not bad to do some coolies.

Some time ago, he also published top-level conference papers and academic papers, which were extremely influential. Bai Songtang and the others had indeed read them.

In contrast, Nan Ming has not published any papers on computers. His ambition is not in scientific research, or in other words, he is not on the traditional path of hard scientific research. What he likes is not publishing papers. What I like is subversion.

In fact, apart from publishing a paper in person when no one came forward at the beginning, Nan Ming basically retreated behind the scenes later, without even a false name.

At first, Bai Songtang felt that Nan Ming's expression and attitude were not very good, he must be upset, after thinking for a long time, he still talked to the person who made the rude remarks just now, and whispered a few words in private, pay attention to the skills of speaking and so on.

This person's surname is Liu, and his name is Hui, which is a very common name. Hearing this, he was quite disapproving, and said: "We are engaged in technology, and he is a businessman, so what kind of talk is there, don't worry, we are all here , he can't leave us alone."

After communicating with Liu Nanchuan, Liu Hui was even more proud, and said to Bai Songtang: "Look, didn't Lanshen Technology invite Da Na to chat with us? But Lanshen Technology's technology is really good, and we chatted with Liu Nanchuan After a while, the harvest is really rich."

Bai Songtang also had to admit that this Liu Nanchuan might really be a skilled master of Lanshen Technology.

But he always felt something was wrong.

Whether it's Nan Ming's expression or Lao Bai's attitude.

After talking with Liu Nanchuan for a while, Bai Songtang proposed that he wanted to visit Qingda Lazy God.

This is nothing, Liu Nanchuan asked for instructions, and agreed.

Bai Songtang and the others left, and Lao Bai stayed in Nanming's office, wanting to say something, but sighed and couldn't speak.

"You saw it too." Nan Ming spread his hands helplessly, "They didn't come here to ask for help, they just came to hear what they like to hear."

What they want to hear is that others support them in developing Tianhe-3, adding more cores, and trying to solve the embargo problem. The so-called coming to ask for help is just to get more people's endorsement.

Of course, this plan is not impossible.

It can even be said that it is very feasible.

For example, in supercomputing, the floating-point computing power is very important, but in fact, the floating-point computing power of the GPU (graphics card) is stronger than that of the CPU. Intel's computing cards and Xeon cores are embargoed, but Nvidia's GPUs are not embargoed. The next step is to directly use domestic supercomputing chips, add Nvidia's GPUs, self-assemble computing cards, and then launch the next generation on this basis It's super calculated.

The domestic GPU design skills are poor, but the CPU design skills for supercomputing are still very good. There are many supercomputers that combine Chinese and Western styles, and even domestically produced supercomputers.

If Tianhe-3 did not consider selling the whole set of plans to the outside world and strengthened secrecy, even if some designs were copied from foreign designs, no one would be able to dismantle them for research, and naturally they would not be prosecuted.

"But obviously there is a better and simpler way." Nan Ming sighed.

Sometimes, he couldn't understand why he didn't use it when there were better things.

Moreover, even if the construction of Tianhe-3 is started now, it may become a backward product before it is completed.

For these huge projects that often require months of demonstration and several years of construction, Lazy Technology is a natural killer, and their replacement speed is too fast.

Let Liu Nanchuan take away Baisongtang and the others, and Nan Ming recruited all the technical masters of the Lazy God Department back, and continued to discuss the next supercomputing development plan.

The first thing I thought about was that Lazy God made its own CPU.

"Actually, if we want to manufacture CPUs, we don't need to find a foundry." Li Yuncong said, "We don't sell CPUs to the outside world. If we use them ourselves, we can design them ourselves and print them out with a 3D printer."

Lazy 3D printers have reached 7nm precision, which is the next-generation process, and now even Intel has not developed a 7nm process.

Of course, a single silicon material has higher requirements for printing, but there is also a "mother machine" in the Lazy God System. The 3D printer that Nanming spent hundreds of energy to strengthen, there is still a lot of free time every day. When a printer is used, a suitable CPU can be created.

"Can you design a CPU?" Su Hongyi stabbed him.

In terms of CPU, Lanshen Technology really doesn't have much accumulation. After all, Lanshen Technology has been established for too short a time. They are still freshmen, so how can they get in touch with all aspects.

"Of course I won't. Isn't there President Nan?" Li Yuncong said, "No matter how we design our manufacturing process, it won't be worse than the new generation Xeon core."

"According to Moore's Law, ordinary computers have almost come to an end." Han Dong shook his head.

"Moore's Law is not necessarily inevitable, and it is not impossible to continue shrinking..." Li Yuncong insisted.

"Moore's Law is of course just a law, and it is possible to break it, but the cost of breaking it is too high, so it is unnecessary." Dongdao Han, "Don't forget, at the 7nm scale, quantum effects have to be considered. The mutual influence between the atoms, if you want to shrink it, you have to make a breakthrough in physics first."

Quantum effects have almost no meaning in the macroscopic world, but when the scale is reduced to the atomic scale, quantum effects immediately start to show their power.

7nm, which is the next-generation process of commercial CPU technology, is almost the limit that is not affected by quantum effects.

No matter how small it is, it is estimated that it can push the technology to 4 nanometers, but it is a bit mysterious.

Even if it is to push down 1 nanometer regardless of cost, it is meaningless.

The limit is right in front of us, and there is no room for further improvement.

Prince Yang, who had been silent all this time, suddenly spoke up, "How about using diamonds?"

"What?" Everyone was taken aback.

"Carbon-based computers." Wang Ziyang said, "Carbon atoms are smaller than silicon atoms, and smaller manufacturing processes can be achieved."

Everyone was dumbfounded, not everyone knew Wang Ziyang's research field, this field was just created by Nan Ming and handed over to Wang Ziyang.

"Carbon atoms...but diamonds are not semiconductors."

Diamond is an insulator, but adding a little conductive impurity to its crystal lattice can make it an optimal semiconductor.

Another characteristic of diamond is its strong thermal conductivity.

Diamond is the most powerful heat conductor among conventional materials, almost none of them, and its thermal conductivity is several times that of copper.

If the ignition point of diamonds can be higher, the deck materials on the aircraft carrier have been worrying, and there is no need to consider special steel, just use diamonds to pave the ground. In a flash, it can directly dissipate the heat generated by the propeller when the aircraft takes off. go to sea.

If you use diamond to make the CPU, you don't need to use cooling agent at all, it will dissipate the heat by itself.

Because of its good thermal conductivity, it is even possible to package several, dozens, or hundreds of CPUs together at the same time to achieve tens of hundreds of core CPUs.

Its efficiency improvement cannot be ignored.

"In addition, there is metal hydrogen. If you add water cooling to the diamond computer, you can use the superconductivity of metal hydrogen..."

Room temperature superconductivity plus superthermal conductivity...

Everyone took a breath.

But these two technologies, they really have. Metallic hydrogen and synthetic diamonds.

"According to my calculations, if we really develop a diamond CPU, we can package nearly a thousand CPUs together to form a computing board, and then immerse these computing boards in water. One-tenth of the area, you can build a diamond computer ten times stronger than the current Qingda Lazy God's computing power."

"Can it really be this strong?" Hearing what Wang Ziyang said, Li Yuncong was taken aback for a moment, then ecstatically.

The current Qingda Lazy God, if he participates in the ranking, can already be ranked among the top three supercomputers in the world.

If diamonds are really used to make CPUs, wouldn't it be far behind other current supercomputers? (To be continued.)
