From university academician to chief academician

Base 111, Laboratory No. 1!

"Researcher Ye!" A research intern said, "This involves P=NP. What should we do?"

Ye Fei’s position at the Supercomputing Center is as a researcher.

Ye Feidao: "Use NP Turing completeness!"

There are seven major problems in mathematics, also known as the Millennium Problem.

If you prove any problem, you will win the highest award in mathematics, the Fields Medal.

Among them is P=NP, which is actually a problem in the computer field.

NP Turing completeness!

It's complicated to explain, so I won't explain it.

All you need to know is that P is a type and NP is a type.

If it can be proved that P=NP.

Human beings will not get sick, they will predict the future just like gods, and their spiritual world will be completely satisfied.

Like artificial intelligence, VR, space navigation, traveling through parallel worlds, any imaginable science fiction event can be realized.

The most exciting thing is that artificial intelligence can tailor-made and provide you with all the needs you have thought of and unexpectedly based on people's psychological and physiological needs.

The intern asked: "What specifically are you referring to?"

Ye Feidao: "Recursively realizable classes composed of recursive sets, gap language and hysteresis diagonal method."

At this time, Ye Fei's cell phone rang.

Ye Fei always turns off his phone when working, but today he had something to do, so he turned it on.

Ye Fei picked it up and took a look. It was a message sent to him by Director Xu.

Director Xu does not do scientific research at the supercomputing center, he only does administrative management, mainly doing some chores.

After all, not everything in the supercomputing center is scientific research. There are also some things that are not scientific research but are relatively complicated.

Director Xu handles these matters.

For example, during today's reception of the multinational delegation, he had to accompany them throughout the entire process.

When these inspection groups go to any base, they send a message to the people at that base to come out and receive them.

After Ye Fei saw the message, he walked outside.

"Researcher Ye!" After Director Xu saw Ye Fei, he shook hands with Ye Fei with a smile and said, "I'll leave it to you, no problem!"

Ye Fei turned his head and glanced at a group of people not far away. There were about twenty people.

Half are Asian, three are Indian and seven are European.

Ye Fei nodded and said, "No problem."

Director Xu walked toward the crowd and said: "Everyone, this is the 111 base. Now, researcher Ye from the 111 base will explain to you the basic situation of the 111 base."

Ye Fei walked to the crowd and said, "Everyone, please come with me!"

Immediately, he led everyone towards the 111 base.

A middle-aged short man asked: "What is the computing power here?"

Ye Fei glanced at him, and Director Xu whispered from the side: "He is Kono Yoshihuai from Japan."

Ye Feidao: "Three trillion times."

"Three exaflops?" A middle-aged man wearing glasses asked doubtfully: "I remember that the number of floating point operations at the Dune Supercomputing Center was 109 exaflops!"

Director Xu said: "This is Professor Yang Sili of Kyoto University of Aeronautics and Astronautics."

Ye Fei nodded to Yang Sili, and he nodded to Ye Fei.

Ye Feidao: "It is true that it used to be 109 petaflops, but we also need to make progress and cannot stand still. A week ago, our computing power has exceeded 3 petaflops."

"This is impossible!" Kono shook his head and said, "I came here two years ago, and your number of floating point operations at that time was still 109 million."

"Can you increase the number by two quadrillion times in just two years?"

Ye Feidao: "How is it impossible to increase the number by two petaflops in two years? In 2010, the number of floating point operations of Tianhe-1 was 257 petaflops. By 2015, the number of floating point operations of Sunway TaihuLight reached 1.254 petaflops. "

"One billion billion times in five years."

"We have increased the number of 2 billion times in two years here, which is not an exaggeration, right?"

Kono said: "The reason why Sunway TaihuLight has such a high number of floating point operations is because of hardware reasons."

“As for Dune’s supercomputer, although it uses the same hardware as Tianhe-1, its operating system is not as good as Tianhe-1.”

Supercomputing values ​​​​hardware as well as software!

Although hardware is important, software is even more important.

Hardware is the foundation and software is the soul.

Hardware determines the starting point of supercomputing, and software determines the end point of supercomputing. Software is the operating system.

"The operating system is not as good as Tianhe-1, but we still need to develop it." Ye Feidao: "Now we use mathematical algorithms to replace the operating system algorithms."

"Mathematical algorithm?" Kono sneered: "Is it the algorithm created by Ye Fei? Can it be applied to supercomputers?"

"This is not a home computer, this is a supercomputer."

"Even Ye Fei himself would find it difficult to do it, right? Can you do it at Base 111?"

The others nodded, yes, this is a super calculation.

Supercomputers are different from home computers. Supercomputers have very high technological content, and both hardware and software are very complex.

The technological content of home computers is as high as that of supercomputers.

In the face of supercomputing, home computers are like the difference between ants and elephants.

Mathematical algorithms can be used on home computers, but it is not certain that they can be used on supercomputers.

Ye Feidao: "If you don't believe it, I can show you the number of floating point operations."

Ye Fei looked at Director Xu next to him. He didn't know if this was okay, so he had to ask Director Xu.

Director Xu nodded. The number of floating point operations was not considered a technical leak.

They just see a set of numbers, not the operating system code.

Ye Fei led everyone into the computing power testing room.

When the people inside saw Ye Fei, they immediately stood up and said, "Researcher Ye."

"Yes!" Ye Fei nodded and said, "Open Benchmark and test the computing power."

Benchmark is a supercomputing power testing software, which is very different from ABTest.

ABTese computing power test is a software used to test computing power on home computers. The test takes a long time and the data is not very accurate.

Benchmark is a software used to test the computing power of supercomputers. The test time is very short. Even the computing power of supercomputers can be tested in a short time.

The number of floating-point operations is within one billion and a billion times, and it can be tested in ten minutes.

The number of floating-point operations is within tens of billions, and it can be tested in one hour.

"OK!"

Ten minutes later, Ye Fei pointed at the computer screen and said, "Everyone, please take a look!"

Everyone was surprised to see that the number of floating point operations reached 305 quadrillion times.

"It's really 305 billion times!" Everyone exclaimed.

"Is this really achieved by mathematical algorithms?" Yang Sili asked.

The rest of the people looked at Ye Fei.

Ye Fei nodded: "It is indeed done by mathematical algorithms. This is just our experimental stage. In the next few months, the computing power will increase rapidly."

"Researcher Ye!" At this time, a middle-aged man rushed in. Seeing Ye Fei, he said excitedly: "The computing power has broken through again."

"Another breakthrough?" Ye Fei's eyes lit up and asked: "How many did it reach this time?"

The experimental process is a process of continuous trying.

Mathematical algorithms were added to supercomputing, and Ye Fei was also crossing the river by feeling the stones. Fortunately, the results were very good.

From 109 petaflops, the number of floating point operations increases by several petaflops every time.

The middle-aged man glanced at the inspection team members with a hesitant expression.

Ye Fei smiled and said: "It's okay, just tell me!"

They spoke in Xia dialect, which the foreigners couldn't understand, but the Xia people were fine with it.

Besides, it would be fine even if those foreigners listened.

Let them know the number of floating point operations. At most, they only know a set of numbers, and it is not a technical leak.

The middle-aged man said: "This time it has increased a lot, 320 million times, an increase of 0.15 billion times."

"So many!" Ye Fei smiled and said, "Not bad!"

"Exceeded 15 million times in one week?" At this time, an Indian in the inspection team said: "You are lying!"

This Indian understands Xia dialect.

He still remembered that Ye Fei said before that 305 quadrillion times was the record a week ago, and now it has exceeded 320 quadrillion times, which means it has exceeded 015 quadrillion times in a week.

If Ye Fei wasn't lying, this would be amazing.

"Huh?" All the Xia people present stared at the Indian, and Ye Fei asked, "Do you understand Xia dialect?"

The Indian said: "I went to university in Xia Kingdom."

"Oh!" Ye Fei nodded: "It did exceed 0.15 billion times a week."

Everyone present who could understand Xia Guo dialect looked at Ye Fei in surprise.

"Impossible!" Professor Yang Sili said in astonishment: "How is this possible!"

This is so amazing. It breaks through 0.15 trillion times in a week. Even God can’t do it.

Ye Fei opened the computing power record chart on his computer. This chart cannot be faked. He recorded it in the background on Benchmark.

Unless, you laboriously recreate a Benchmark, and then laboriously create a computing power record chart in the background.

But few people do this thankless task.

What’s the point of even doing it!

"Please take a look!" Ye Feidao said: "This is our computing power breakthrough in the past two months."

Those present who could not understand Xia Guo's dialect all looked at the computing power record chart after the others explained.

After reading it, they exclaimed: "How is this possible?"

The chart records that it only took two months for the computing power to break through from 108 petaflops to 305 petaflops.

Yes, it just exceeded 320 billion times.

It exceeded 212 billion times in two months. Isn’t this a dream?

Yang Sili said excitedly: "Is this really done by mathematical algorithms??"

"Of course!" Ye Fei nodded.

Everyone was stunned, not expecting that mathematical algorithms could really be used in supercomputing.

And the effect is so good.
