Su Yang said: "Off topic, we don't need to mention it." Professor Yang, let me tell you this, HPC clusters, I don't want to build them. ”

"This ......" Hearing Su Yang's words, Yang Qingtao was stunned.

Didn't you say okay, why did you suddenly change your hexagram again?

That's not how the script is written.

"Mr. Su, didn't we have a good chat just now, how can you ...... this" Yang Qingtao was anxious, and he was blushing and wanted to say something.

Su Yang raised his hand to stop him and said, "Professor Yang, don't worry, listen to me." ”

"Mr. Su, you say. Yang Qingtao took a breath.

Su Yang said: "I mean, there is no need to build an HPC cluster, we have to do it better, and build it directly...... Supercomputer!"

Yang Qingtao: ???

"Supercomputing!"

Yang Qingtao's face showed a look of astonishment, and Wang Han was also stunned for a moment.

"That's right, the core is supercomputing, not a cluster of high-performance computers. ”

Hearing Su Yang's affirmative words, Yang Qingtao felt that his brain was a little short-circuited, and his eyes flickered violently.

"Mr. Su, you're not kidding, supercomputing...... Supercomputing is not an ordinary thing, and it costs more than twice as much to build as an HPC cluster. ”

In other words, the most cost-effective way to build a cloud computing base is to use HPC clusters.

And supercomputing ...... The difference between the two is equivalent to the HPC cluster being the BMW X1, while the supercomputer is a Ferrari 488.

Although this comparison is somewhat incorrect, it is enough to show that the cost of building between the two is huge.

Of course, if the cloud computing base is centered on supercomputing, the performance will undoubtedly be better than that of HPC clusters.

Su Yang said: "Professor Yang, I'm not joking with you, Yuanyang's cloud computing base does not take HPC clusters as the core, its core is supercomputers. ”

HPC cluster is an egg, I want supercomputing, supercomputing!

Where did quantum computers come from without supercomputing?

Seeing that Su Yang was so solemn, Yang Qingtao took a breath and hurriedly said: "I have participated in the construction project of the top supercomputer, and I have some experience and experience, as long as the money is in place and the manpower is enough, it is not a problem to build a supercomputer." ”

Su Yang waited for him to say this.

A smile appeared on his lips, and Su Yang said, "Then Professor Yang, you estimate, how much is the budget for building a supercomputer?"

Yang Qingtao said: "The key depends on what performance supercomputing you want from Mr. Su, if it is a supercomputer with a continuous speed of 1000Tflops, there will probably be hundreds of thousands of core processors, well, one will cost at least one billion, not counting land and other buildings." ”

"In addition, if a supercomputer of this scale is used to support the operation of cloud computing bases, the annual electricity bill will be at least 30 million or more. ”

flops is the number of floating-point operations, and 1T is equal to 10 to the 12th power, which is one trillion.

1000Tflops is 1 quadrillion operations per second.

Su Yang: "What if you want to build a 10,000Tflops supercomputer?"

"10,000Tflops?" Yang Qingtao was stunned.

"No way?"

Yang Qingtao said with a smile: "Mr. Su, you should know floating point operations, a supercomputer with a continuous speed of 10,000Tflops, the number of operations per second is equivalent to 100 million billion." ”

"That's right. Su Yang nodded.

Yang Qingtao continued: "However, the supercomputer that currently ranks first in the world, the 'Titan' supercomputer developed by IBM in the United States, has 7,500 trillion calculations. ”

"That's it?" Su Yang's brows suddenly furrowed.

When he first got the quantum supremacy integrated card, he also felt that it was difficult to collect three 100 million supercomputers, but it was not too difficult.

But now that I look at it, there is no such fast supercomputing in this world at all.

The fastest is only 7,500 trillion times, which is four or five years worse than the previous life.

Su Yang vaguely remembered that before crossing the Tianhe-2 in Huaxia, the peak of the operation broke 300 million times, and there was an even more powerful supercomputer, which broke 1 billion.

And the world's fastest supercomputing is only 75 million times per second.

That's a ...... It's too showy, isn't it?

Yang Qingtao said: "At present, it is like this, but it is changing every year, two years ago, the peak of supercomputing just exceeded 1 quadrillion, but this year it reached 7500 trillion times, maybe next year, it will be able to break through 100 million times." ”

Su Yang said in a deep voice: "The supercomputer that Yuanyang wants to build, the number of calculations cannot be less than 100 million billion times per second, Professor Yang, you have to think of a way." ”

Yang Qingtao glanced at him strangely and said: "There is a way, if you don't consider the overall performance, just look at the computing speed, increase the number of core processors, and then expand the running memory." ”

"But Mr. Su, this is not only an increase in expenses, but also a failure to get tens of billions of dollars, and ...... Even the annual electricity bill will be an astronomical amount, a billion less a year, I'm afraid it will ......"

The reason why supercomputing is supercomputing is not only powerful computing power, but also because of its huge energy consumption, which is not something that ordinary people can afford.

Of course, if you optimize important power-hungry cores such as CPUs, the energy consumption will be greatly reduced.

Perhaps in the next few decades, people will see that a computer with a power of a few hundred watts can make operations at a speed of 100 billion exacerbations per second, or even faster.

But now, the technology is not up to standard, it is just a luxury.

Su Yang's eyes moved, and he said: "As long as it can be built, since we want to do it, we will do our best, money is not a problem." ”

Glancing at Yang Qingtao, Su Yang said: "Professor Yang, about the matter of building supercomputing, for the time being, it will be decided like this, if there is no problem, you can sign the contract later, and take a good rest after you go back, starting next year, the construction of Yuanyang's cloud computing base will be handed over to you." ”

"Mr. Su, you really want to build a supercomputer, in fact, I think supercomputing is too expensive, or HPC clusters are more cost-effective." Su Yang was so crisp, Yang Qingtao suddenly felt a little embarrassed.

"What, Professor Yang, don't you want to make the quality of your work better?" said Su Yang.

"No, of course I hope!" Yang Qingtao said busily.

"Since this is the case, then the matter is decided, Mr. Chen, the matter of signing the contract with Professor Yang will be handed over to you. ”

"Understand Mr. Su. Chen Feng got up and answered.

After the meeting, Yang Qingtao also signed a contract with Yuanyang and became the chief engineer of Yuanyang Technology Development Company, a subsidiary of Yuanyang Group, responsible for the construction of cloud computing base.

The annual salary is 2 million yuan, plus a certain housing subsidy.

The treatment equivalent to the academician level is placed on Yang Qingtao, and Yuanyang's side is considered to be sincere.

The moment he walked out of the building, Yang Qingtao suddenly felt that the world had changed.

He held his head high and was full of energy.

"Yuanyang Group...... Unexpectedly, his courage is even stronger than I imagined!" Yang Qingtao sighed.

Wang Han said on the side: "Teacher, Yuanyang really wants you to build a supercomputer for them?"

"Can there be a fake? It is clearly written in black and white, I can't break the contract, and they can't break the contract, otherwise neither side can please me." ”

"Then I will congratulate you in advance, teacher, the construction of the cloud computing base, you said, it is your hard work in the second half of your life, and now it is finally going to be realized. ”

"If nothing else, it should be fine. Yang Qingtao smiled on his lips, and said: "However, in this way, I won't be able to teach you next semester at Yan University, and I have to be more conscious in school." ”

"I'm not going to be lazy teacher. ”

"Yuanyang is a good company, the boss is also a bold young man, if you don't work in the state in the future, Yuanyang will be your best choice. ”

Wang Han nodded, but sighed: "Alas, speaking of which, Senior Brother Su Yang is so powerful, I am really far behind him." ”

To be honest, after listening to that meeting, Wang Han was a little shocked.

Whether it is vision, thinking or conversation, he thinks that he can't be compared with Su Yang.

Back then, he was also the second best person in Jianghai City after science......

Yang Qingtao comforted: "Don't think too much, he is not a character you can compare, let alone you, even I have to work for him now, and I have to be willing to thank him." This is a very powerful person. ”

As he spoke, Yang Tao couldn't help but think of the stupid things he said when he first met Su Yang before,

The more I thought about it, the more I felt that my old face was flushed, my heart was embarrassed, and I had the urge to jump off the building.
