Of course, Liu Nanchuan wanted to stay, although he was not qualified to participate in the core secrets of Lazy God Technology, such as the books that had been strengthened by Nanming, but just the knowledge he learned from Su Hongyi and Han Dong had 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 small transparent, and now Liu Nanchuan can cause an earthquake in the industry by stomping his feet after going out.

Liu Hui was blindless, and he kept talking to Liu Nanchuan: "Old Liu, your current relationship is still in Qingyang University, then it will be easy to do." If Qingyang University doesn't release you, we can lower the order, and Qingyang University won't dare to card you!"

"I said I don't want to go anywhere else. "Liu Nanchuan's face is unhappy, the lazy god department is like the hidden sect in martial arts novels, although it is hidden in the mountains, but it can't stand the invincibility of the gods, after going out, it is a peerless swordsman, at this time, you have a bad street sect like Shaolin Temple to come to me, is it enough?

Without speculating for more than half a sentence, Liu Hui offended Liu Nanchuan, a good old man, and the next visit was definitely not pleasant.

Originally, there were many places where two sentences could be exchanged, but Liu Nanchuan didn't bother to communicate, so he took a sentence and hurriedly went through the motions, even if he took them to visit.

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

Liu Nanchuan looked at Lao Bai's face and gave Bai Songtang a little thin noodles, which brought the rhythm back a little.

Bai Songtang wanted to resolve the contradiction between the two sides, but he walked around in Qingda and listened to Liu Nanchuan's introduction, so he didn't care about anything else.

In the domestic supercomputing community, and even in the international supercomputing community, Qingda lazy gods are very low-key. Not much of a showmanship.

The international supercomputing community, the top 500 statistics, is released twice a year in November and June.

Therefore, Tianhe-2, which was built in 2013, has won four consecutive championships by November 2014. As expected, June will soon see five consecutive championships.

And the Qingda Lazy God was only officially released to the public in November last year, so until now, there is no shadow of the Qingda Lazy God on any official list.

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

This supercomputer comes from the book of the Southern Darkness Enhancement, and the CD-ROM example that comes with it. There is almost no upper limit to the expansion limit, and the efficiency is amazing.

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

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

But the most terrible. However, the number of its cores is only 300,000, which is only one-tenth of that of Tianhe-2. The computing power is about one-third of it.

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

"How is this possible?" Looking at the statistics, Liu Hui couldn't help but say, "You're bragging." ”

Liu Nanchuan: "Hehe......"

Too lazy to brag to you.

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

It is not that the more cores a computer has, the more efficient it is, but the communication between chips, the coordination of chips, and the interference between each other. It's all learning.

In the simplest example, gamers like to plug two graphics cards into the case and play a dual-graphics crossfire, but the energy efficiency of the dual-graphics crossfire is not doubled, but only about 20%.

"On the one hand, it comes from the architecture, 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 give greater play to the capabilities of hardware, and the hardware and software have been optimized for a long time." ”

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

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

"What's the secret?" asked Liu Hui with wide eyes, and took out a small notebook casually, intending to write it down.

"Lazy god black technology. Liu Nanchuan said, what he said is very reasonable.

With the addition of lazy god black technology, isn't everything logical?

"Lao Liu, Lao Liu, you are not real, you are still keeping it secret from me, who are the two of us, wait until you get to us......"

Doesn't this person understand people's words? Liu Nanchuan looked at Bai Songtang with a puzzled face.

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

"Excuse me. Liu Nanchuan still has a good impression of Bai Songtang, and he is very polite when he hears it.

"Now how many cores can the parallel program of Qingda Lazy God support?"

"At present, there are only 300,000 cores of the Qingda Lazy God, and all of them have been used, but theoretically speaking, there is no problem with the current program running on the Qingda Lazy God to reach 10 million cores. Liu Nanchuan said.

Blow, you blow!" Liu Hui stared at Liu Nanchuan as if he were looking at a neuropath.

At present, Tianhe-2 has the most cores in the world, and there are only more than 3 million cores, but except for a very small part of the software, most of the programs of Tianhe-2 can only use hundreds of thousands, or even more than 100,000 cores.

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

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

Bai Songtang silently looked at the various data on it, as well as some simple explanations of the technology, and after a while, he frowned and said, "Your supercomputer can be infinitely expanded?"

The theoretical value can reach 100 billion times, for the Qingda lazy god who is only 100 million times now, a thousand-fold increase, isn't it infinite expansion?

Liu Nanchuan nodded and said, "The Qingda Lazy God is now limited by space constraints, and there is nowhere to expand. "After all, the Supercomputing Institute of Qingyang University is just an academy-level supercomputer, and the reserved space is not large.

Bai Songtang watched silently for a long time, and reached out to grab Liu Nanchuan.

"Lao 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 supercomputing, Tianhe-3 will be able to lead the world for at least ten years!

Liu Nanchuan was speechless, don't you eat so ugly one by one, okay?

"I'm afraid Professor Liu can't go to the National Defense Science and Technology University, but if you want, we can sell you a supercomputer. Su Hongyi walked over and stretched out his hand to Bai Songtang: "Hello, I am the director of the supercomputing department of Lazy God Technology, and my name is Su Hongyi." ”

During the winter vacation, Nanming once asked all of them to start a business, and Su Hongyi also made a plan, but the effect was average.

Seeing that Tie Dan has a lazy life, Feng Tianyou has a lazy God Shipyard, and even the unobtrusive Prince Yang has burst out of his endless potential and has become a hot big man now, Su Hongyi of course has his own ideas.

As the director of the supercomputing department of the lazy god department, of course, supercomputing is not only money-consuming, but also very profitable!

To a certain extent, supercomputing is like a factory, where chaotic data is fed in and the results are output.

It is profitable to build a factory, and it is also profitable to process items after the factory is built.

Although for the lazy god department, the current Qingda lazy god can no longer keep up with the speed of development, but for the entire supercomputing world, it is super advanced, as long as it is taken out, it can crush the current supercomputing market!

Now, Lazy God Technology has begun to consider the next generation of supercomputing, so Qingda Lazy God is outdated, this outdated technology, can it be used to press the bottom of the box?

Of course, it's going to be taken out to grab money!

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

Su Hongyi suddenly seemed to have been beaten with chicken blood, and came out to be the boss independently?

And Bai Songtang, they were originally annoying, but suddenly, in Su Hongyi's eyes, they were fragrant, isn't this a door-to-door business? )
