Chapter 646: Diamond Computer?

When he did not become President Nan and was just an ordinary person who paid attention to the dynamics of science and technology, Nanming was still very proud of Tianhe-2 to continue to top the list.

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

Tianhe-2 rarely runs at full capacity, and so far, there is no calculation project that can allow Tianhe-2 to fully exert its strength, this feeling is like a peerless swordsman, who has cultivated peerless martial arts, but can only fight with the villagers.

This made Nanming of the Practical Party deeply regretful.

Nanming really thinks that it is more important to let the current Tianhe-2 run at full capacity, truly give full play to the advantages of supercomputing, and accumulate experience in making supercomputing operate at full capacity.

Because that's next, there's going to be a change that will reshape the entire computer science community.

This kind of change is not because of others, but because of Lazy God Technology.

In the discussion between Nanming and Lazy God Technology just now, although there is no conclusion yet, the basic idea has been determined.

That is, the lazy god system began to officially enter the chip industry.

But the sudden appearance of the glass heart made Nan Ming suddenly realize that he seemed to be a little too enthusiastic, and even a little shaved and hot.

Nanming was born generous and helpful, because of Lao Bai's relationship, Nanming regarded Bai Songtang as his own person, and he did not shy away from the people around Bai Songtang, but at this time, people did not necessarily regard him as their own.

After being sarcastic, Nan Ming suddenly laughed.

Since people are business-oriented, then treat them with a business-like attitude, and there is no need to open a small stove.

Then he let go of Bai Songtang's hand. Said: "Look at me, I'm just talking to you, so let's introduce one of our supercomputing experts, and you can communicate." ”

Nan Ming directly ordered: "Da Bai, call Professor Liu Nanchuan and Liu." ”

Da Bai let out a beeping sound. It's kind of a feedback from Nanming's order.

"Professor Liu Nanchuan is the master of the computer department of Qingyang University, he is very good at supercomputing, and he has published several papers recently, I believe you have also read it, and you will communicate with Professor Liu Nanchuan later, I have some other things to deal with. ”

Nan Ming said, and stretched out his hand to send the guest.

Professor Liu Nanchuan arrived soon, and although he was a little confused, he still greeted a few people warmly.

Confused, he was led out of Nanming's office. Bai Songtang frowned and didn't know what he was thinking, and the person behind him was satisfied: "That's right, a hairy kid who doesn't know anything, what nonsense to say...... Supercomputing competition, what does he know!"

No matter what time it is, Nanming's age can be regarded as a fatal injury. Especially this kind of person who comes out of a place where seniority is more serious, although he sees too many people who soar because of their talents, abilities, and abilities. But most of the mediocre talents are waiting in line, waiting for the fruits to be shared.

As a mediocre person, he naturally thinks that others are mediocre.

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

Lao Bai stood aside with a wry smile and watched, watching Liu Nanchuan chatting with a few people, but there was no barrier.

Liu Nanchuan is one of the big names in the School of Computer Science of Qingyang University. Because of the relationship between Nanming and others, the entire School of Computer Science has almost become the self-reserved place of Lazy God Technology, and the expanding Qingda Lazy God has almost turned the Supercomputing Research Institute of Qingyang University into the Supercomputing Operation and Maintenance Department of Lazy God Technology, and the Planning and Information Institute of Qingyang University is regarded as a cheap labor market.

A group of hard-working graduate students, who played the role of cheap labor, followed their teachers, and became hard laborers who did not need money, and were busy expanding, expanding, and expanding again for the lazy god of Qingda every day.

But the process is not without its rewards.

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

In the process of actually dealing with various problems and failures, Liu Nanchuan learned a lot of advanced knowledge from his former students, and now his boss Su Hongyi and Han Dong.

This is still for the sake of Bai Songtang's face.

During this time, it was a period of rapid rise for Liu Nanchuan, and Liu Nanchuan even felt that in another year or two, he would be able to start a sect and write books.

And the batch of doctoral and master's students who are regarded as cheap labor have also advanced by leaps and bounds, and some time ago, there was even a master's degree who published a very influential thesis, which was widely praised.

And this increase, almost average, is not one or two, but tens or hundreds.

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

And Liu Nanchuan got the moon first near the water, he could put it down, and his attitude was also very correct, and he consciously helped Su Hongyi and Han Dong to help, to be honest, even the core code of Qingda Lazy God has been exposed to a lot, and he also has a task distribution system, he contributed a little code to the program of playing Doudou at the beginning, although his talent is not as good as the lazy god system "gods" that have been strengthened by various books, but it is not bad to do some coolies.

Some time ago, he also had top conference papers and academic papers published, which had a great influence, and Bai Songtang they had indeed seen it.

In contrast, Nanming has not published any papers in terms of computers, his ambition is not in scientific research, or in other words, it is not in the traditional hard scientific research path, what he likes is not to publish papers, he likes to subvert.

In fact, since no one came forward at the beginning, he personally published a paper, and then Nanming basically retreated into the background, and he didn't even want a false name.

Bai Songtang felt that Nan Ming's expression and attitude were not very good at first, he must have been unhappy, and after thinking about it for a long time, he still talked about the person who was disrespectful just now, and whispered a few words in private, paying attention to the skills of speaking.

This man's surname is Liu. Minghui, a very ordinary name, was quite unimpressed when he heard this, and said: "We are engaged in technology, he is a businessman, what kind of mouth cannon is he putting over there." Don't worry, we're all here, he can't leave us aside. ”

After communicating with Liu Nanchuan, Liu Hui was even more proud, and said to Bai Songtang: "Look, didn't Lazy God Technology still invite Da Na to talk to us? But the technology of Lazy God Technology is really good, and after chatting with Liu Nanchuan for a while, the harvest is really rich." ”

Bai Songtang also had to admit that this Liu Nanchuan. Maybe it's really the technology master of Lazy God Technology.

But he always felt that something was wrong.

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

After communicating with Liu Nanchuan for a long time, Bai Songtang proposed that he wanted to visit the lazy god of Qingda.

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

Bai Songtang and they left, and Lao Bai stayed in Nanming's office, wanting to say something. But he sighed and couldn't speak.

"You saw it too. Nanming had no choice but to spread his hands. "They're not really here to ask for help, they're just here to hear what they like. ”

What they want to hear is that others support them to develop Tianhe-3, pile up more cores, and find a way 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 doable.

For example, in supercomputing, floating-point computing power is very important, but in fact, the floating-point computing power of GPUs (graphics cards) is stronger than that of CPUs. Embargoed Intel's computing cards and Xeon cores. But there is no embargo on NVIDIA's GPU, the next step is to directly use domestic supercomputing chips, plus NVIDIA's GPU, self-assembled computing cards, and then launch the next generation of supercomputing on this basis.

The domestic GPU design foundation is very poor, but the CPU design skills for supercomputing are still very good, and there are many supercomputers that combine Chinese and Western and even domestic products.

If Tianhe-3 does not consider selling the entire set of plans to the outside world and strengthens secrecy, even if some designs are copied from foreign designs, no one can dismantle them for research, and naturally they will not be prosecuted.

"But there's a better, easier way. Nanming sighed.

Sometimes, he doesn't understand why he doesn't use something better.

Moreover, even if Tianhe-3 is built now, I am afraid that it will immediately become a backward product before it is completed.

For these huge projects, which often take months to demonstrate and build in several years, Lazy God Technology is a natural killer, and they are updated too quickly.

Let Liu Nanchuan take away Bai Songtang and them, and Nanming recruited all the technical masters of the Lazy God Department back, and continued to discuss the next development plan of supercomputing.

The first thing I thought about was that the lazy god made the CPU himself.

"Actually, if we want to make a CPU, we don't have to find a foundry. Li Yuncong said, "We don't sell CPUs to the public, if we use them ourselves, we can design them ourselves and print them out with a 3D printer." ”

The accuracy of the lazy god 3D printer has reached the level of 7nm, which is already the next generation of process, and now even intel has not developed a 7nm process.

Of course, a single silicon material has higher requirements for printing, but the lazy god department also has a "mother machine", the 3D printer that has been strengthened by hundreds of energy spent by Nanming, and there is still a lot of free time every day, and when you get together a few printers, you can build a suitable CPU.

"Do you know how to design a CPU?" Su Hongyi stabbed him.

In terms of CPU, Lazy God Technology really has no accumulation, after all, Lazy God Technology has been established for too short a time, and these people are still freshmen, how can they be all-encompassing and exposed to all kinds of aspects.

"Of course I won't, isn't there Mr. Nan?" Li Yuncong said, "Our manufacturing process, how to design it, will not be worse than the new generation of Xeon core." ”

"According to Moore's Law, the average computer is now almost at the end of its life. Han Dong shook his head.

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

"Moore's Law is, of course, just a law, and it is possible to break it, but the cost of breaking it is too great to be necessary. Han Dong said, "Don't forget, at the scale of 7nm, we already have to consider quantum effects and the interaction between atoms, and if you want to shrink it, you have to make a breakthrough in physics first." ”

Quantum effects mean almost nothing in the macrocosm, but when the scale is lowered to the atomic scale, quantum effects immediately start to exert their power.

7nm, the next generation of commercial CPU technology, is almost the limit of 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 the cost, it does not make sense.

The limit is at hand, and there is no room for further improvement.

Prince Yang, who had been silent, suddenly spoke, and said, "How about using diamonds?"

"What?" everyone was stunned.

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

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

"Carbon atoms...... But diamond is not a semiconductor. ”

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

Another property of diamond is its strong thermal conductivity.

Diamond is the most powerful heat conductor in conventional materials, almost one of them, and its thermal conductivity is several times that of copper.

If the ignition point of diamonds can be higher, the deck materials that have been troubled on the aircraft carrier do not need to consider special steel, and can be directly paved with diamonds, and in an instant, it can directly dissipate the heat generated by the propellers when the aircraft takes off into the sea.

If you use diamond to make a CPU, you don't need to use a heatsink at all, and it spreads the heat out on its own.

Because of its good thermal conductivity, it can even pack several, dozens, hundreds of CPUs together at the same time, so that dozens and hundreds of cores can be used.

Its efficiency improvement is also not negligible.

"In addition, there is metallic hydrogen, and if you add water cooling to the diamond computer, you can take advantage of the superconducting properties of metallic hydrogen......"

Superconductivity plus superconductivity at room temperature......

Everyone took a breath.

But these two technologies, they really have. Metallic hydrogen and man-made diamonds.

"According to my calculations, if we really develop a diamond CPU, we can package nearly 1,000 CPUs together and turn them into a computing board, and then immerse these computing boards in water, and use about one-twentieth of the area of the current Qingda Lazy God to build a diamond computer that is ten times stronger than the current Qingda Lazy God's computing power. ”

"Can it really be so strong?" Hearing Wang Ziyang say this, Li Yuncong was stunned for a moment, and then ecstatic.

The current Qingda lazy god, if he participates in the ranking, can already rank among the top three supercomputers in the world.

If diamonds were really used to make CPUs, wouldn't it be far behind the other supercomputers that are now available? )
