Chapter 650: Door-to-Door Business

Of course Liu Nanchuan wants to stay. Although he is not qualified to participate in the core secrets of Lanshen Technology, such as the books strengthened by Nanming, but only the knowledge he learned from Su Hongyi and Han Dong is enough. It has already benefited Liu Nanchuan a lot.

A few months ago, as an ordinary professor in the Computer Department of Qingyang University, Liu Nanchuan could only be regarded as a little transparent. Now Liu Nanchuan can cause earthquakes in the industry by stomping his feet after going out.

Liu Hui was a wink, and kept talking to Liu Nanchuan: "Old Liu, your current relationship is still in Qingyang University, so it will be easy to handle. If Qingyang University doesn't let you go, we can lower the order, Qingyang University Yang University dare not block you!"

"As I said, I don't want to go to other places." Liu Nanchuan looked unhappy. The lazy god is like the hidden sect in martial arts novels. Although it is hidden in the mountains, it can't stand the invincible magic. After going out, it is peerless Swordsman, at this time, you, a bad street sect like Shaolin Temple, come to me, are you qualified enough?

The words were not speculative, and Liu Hui offended Liu Nanchuan, a good old man, and the next visit was definitely not a pleasant one.

Originally, there were many places where we could exchange a few words, but Liu Nanchuan didn't bother to communicate. He just said a word and went through the scene in a hurry, even if he had finished showing them around.

Bai Songtang felt Liu Nanchuan's change of attitude immediately, but unfortunately, he couldn't restrain Liu Hui, so he could only apologize to Liu Nanchuan in private.

Seeing Lao Bai's face, Liu Nanchuan gave Bai Songtang a bit of a face, and then pulled the rhythm back a little.

Bai Songtang wanted to resolve the conflict between the two parties, but after wandering around Qingda Lazy God, after listening to Liu Nanchuan's introduction, he couldn't care about anything else.

In the domestic supercomputing industry, and even in the international supercomputing industry, Qingda Lazy God is very low-key and does not show much limelight.

The international supercomputing community, which counts the top500, releases statistical data twice a year in November and June.

Therefore, Tianhe-2, which was built in 2013, had won four consecutive championships by November 2014. If it is not expected, it will usher in a fifth consecutive championship in June soon after.

The Qingda Lazy God was only officially released in November last year, so up to now, there is no shadow of Qingda Lazy God on any official ranking list.

But the original press conference made Qingda Lazy God's supercomputer famous.

This supercomputer comes from Nan Ming's enhanced books, and the attached CD example has almost unlimited expansion limit, and its efficiency is even more astonishing.

After several months of expansion, Qingda Lazy God now has 300,000 cores, with a peak computing power of 120 billion operations per second and an average computing power of 109 million million operations per second.

This data has steadily surpassed the Japanese supercomputer "Jing", which ranks fourth in the world, and is only below the three supercomputers Tianhe-2, Titan, and Sequoia.

But the most frightening thing is that it only has 300,000 cores, only one-tenth of Tianhe-2, but its computing power is about one-third of that.

Its energy efficiency is several times higher than all supercomputers in the world!

"How is this possible?" Looking at the statistical data, Liu Hui couldn't help but said, "You're bragging."

Liu Nanchuan: "Hehe..."

I'm too lazy to brag with you.

"Professor Liu, how can this kind of thing be possible? I remember that when the Qingda Lazy God was first released, the energy efficiency was amazing, but at that time, the Qingda Lazy God only had more than 5,000 cores, and it has increased by now. Sixty times, how could the efficiency not decrease?"

Computers do not mean that the more cores there are, the stronger the performance. The communication between chips, the coordination of chips, and mutual interference are all knowledge.

The simplest example is that gamers like to plug in two graphics cards in the chassis and play a dual-graphics crossfire, but the energy efficiency of dual-graphics crossfire does not double, but only increases by about 20%.

"This aspect comes from the structure, and on the other hand, it comes from optimization." Liu Nanchuan said, "The system used by Qingda Lazy God is a completely independent system, which is different from all operating systems on the market, and can make greater use of hardware. The capabilities, and hardware and software, have been optimized for a long time."

"I don't believe it!" Liu Hui shook his head, "I saw it just now. The hardware you use is all general-purpose hardware. No matter how powerful the software is, it is impossible to break through the limitations of the hardware!"

"Of course, we have a secret." Liu Nanchuan laughed.

"What secret?" Liu Hui asked with wide eyes, took out a small notebook, and planned to write it down.

"Lazy god black technology." Liu Nanchuan said, taking it for granted.

With the addition of Lazy Black Technology, isn't everything logical?

"Old Liu, old Liu, you are not real, and you still keep it a secret from me, which one of us is with whom, when you get to our place..."

Does this person understand human speech? Liu Nanchuan looked at Bai Songtang with doubts on his face.

"Can I ask a question?" Bai Songtang asked cautiously.

"Excuse me." Liu Nanchuan still had a good impression of Bai Songtang, and he was very polite when he heard the words.

"How many cores can Qingda Lazy God's parallel program support at most?"

"At present, Qingda Lazy God only has 300,000 cores, and all of them have been used, but theoretically speaking, there is no problem with the programs running on Qingda Lazy God reaching tens of millions of cores." Liu Nanchuan said.

Blow, just blow! Liu Hui stared at Liu Nanchuan, as if watching a psychopath.

10 million cores? At present, Tianhe-2 has the most cores in the world, and it only has more than 3 million cores. However, except for a very small part of software, most of the programs of Tianhe-2 can only use hundreds of thousands, or even tens of thousands of cores. Thousands of cores.

For Tianhe-2, if the more than three million cores cannot be used at the same time, it is an extremely wasteful behavior.

Not to mention Liu Hui, even Bai Songtang didn't believe it, Liu Nanchuan didn't say anything, took out a technical document and handed it to Bai Songtang.

Bai Songtang silently looked at the various data above, as well as some simple technical explanations. After a while, he frowned and said, "Your supercomputer can be infinitely expanded?"

The theoretical value can reach hundreds of billions of times. For Qingda Lazy God, who only has billions of times, what is a thousand times improvement, not infinite expansion?

Liu Nanchuan nodded, and said, "Qingda Lazy God is limited by the space constraints, and there is nowhere to expand." After all, Qingyang University's Supercomputing Research Institute is just a college-level supercomputer, and the reserved space is not enough. big.

Bai Songtang watched silently for a while, then stretched out his hand to grab Liu Nanchuan.

"Old Liu, I sincerely ask you, are you willing to come to our National Defense Science and Technology University?"

If this technology can be added to the next generation of supercomputers, Tianhe-3 will be at least ten years ahead of the world!

Liu Nanchuan is speechless, don't you all look so ugly, okay?

"Professor Liu may not be able to go to the University of National Defense Science and Technology, but if you want, we can sell you a supercomputer." Su Hongyi walked over and extended his hand to Bai Songtang: "Hello, I am Lanshen Technology The supervisor of the supercomputing department, my name is Su Hongyi."

During the winter vacation, Nan Ming asked all of them to start businesses, and Su Hongyi also made a plan, but the effect was mediocre.

Seeing that Tie Dan has a lazy life, Feng Tianyou has a lazy shipyard, and even the incongruous Wang Ziyang has exploded with endless potential and has become a hot boss. Of course, Su Hongyi also has his own ideas.

As the supervisor of the supercomputing department of the Lazy God Department, supercomputing is of course not just a waste of money, it can also make a lot of money!

To some extent, supercomputing is like a factory, where chaotic data is input and orderly results are output.

Building a factory can make a profit, and processing items after the factory is built can also make a profit.

Although for the lazy god system, the current Qingda lazy god can no longer keep up with the speed of development, but for the entire supercomputing industry, it is super advanced. As long as it is taken out, the current supercomputing market can be completely wiped out. crush!

Now, Lanshen Technology has begun to consider the next generation of supercomputers, so Qingda Lanshen is considered outdated. Is this outdated technology used as a bottom of the box?

Of course it is to take it out to grab money! Otherwise, what a waste?

In the morning, Su Hongyi brought a report to Nanming, Nanming nodded in agreement, and said to Su Hongyi: "If you can make the supercomputing famous, I can separate the supercomputing department and make it a separate company!"

Su Hongyi suddenly seemed to have been beaten to death, and became the boss on his own? It feels cool to think about it!

As for Bai Songtang and the others, they were still disgusting at first, but suddenly, in Su Hongyi's eyes, they were sweet and sweet. Isn't this a door-to-door business? (To be continued.)
