From a university student to a chief academician

Chapter 47 3.2 billion times

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 a researcher.

Ye Feidao: "Use NP Turing completeness!"

There are seven major problems in mathematics, also known as the millennium problem.

Prove that any problem can be won 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.

Just need to know that P is a class and NP is a class.

If it can be proved that P=NP.

Human beings will not get sick, human beings will be like gods, predict the future, and the spiritual world of human beings will be fully satisfied.

Artificial intelligence, VR, space travel, traveling through parallel worlds, and any sci-fi events that can be imagined can be realized.

The coolest thing is that artificial intelligence can tailor and provide you with all the needs you have thought of and unexpected according to people's psychological and physical needs.

The intern said, "Which specific aspect are you referring to?"

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

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

Ye Fei always turned off his mobile phone when he was working, but today he turned on his mobile phone because he had something to do.

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

Director Xu doesn't care about scientific research at the supercomputing center, he only cares about administrative management, and mainly does some chores.

After all, in the supercomputing center, not everything is scientific research, and there are some complicated things that are not scientific research.

These matters are handled by Director Xu.

Just like the reception of the multi-national inspection team today, he had to accompany him throughout the process.

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

After seeing the message, Ye Fei walked outside.

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

Ye Fei turned his head to look at a group of people not far away, there were about 20 people.

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

Ye Fei nodded and said, "No problem."

Director Xu walked towards the crowd and said, "Everyone, this is Base 111. Next, Researcher Ye from Base 111 will explain the basic situation of Base 111 to you."

Ye Fei walked up to the crowd and said, "Everyone, please follow me!"

Immediately, he led the crowd to the 111 base.

A middle-aged short man asked, "How much computing power do you have here?"

Ye Fei glanced at him, Director Xu whispered beside him, "He is Kono Yoshii from Dongying Kingdom."

Ye Fei said: "Three billion billion times."

"Three billion billion times?" A middle-aged man wearing glasses asked suspiciously: "I remember that the number of floating-point operations in the Dune Supercomputing Center is 1.09 million million times!"

Director Xu said: "This is Professor Yang Sili of Kyoto Aeronautical University."

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

Ye Feidao: "It is true that it used to be 1.09 million billion times, but we still have to make progress. It is impossible to stand still. A week ago, our computing power has broken through to [-] million million times."

"That's impossible!" Kono shook his head and said, "I also came here two years ago, and your floating-point calculations were still 1.09 million billion times."

"Can you add two billion billion times in just two years?"

Ye Feidao: "How is it impossible to increase by 2010 billion times in two years? In 2.57, the number of floating-point operations of Tianhe-2015 was 12.54 million times. By [-], the number of floating-point operations of Sunway TaihuLight reached [-] trillion times. "

"One billion billion times more in five years."

"It's not an exaggeration for us to increase [-] billion times in two years!"

Michi Kono: "The reason why Sunway TaihuLight has such a high number of floating-point calculations is because of the hardware."

"As for Dune's supercomputer, although the hardware used is the same as Tianhe-[-], the operating system is not as good as Tianhe-[-]."

Supercomputers value both hardware and software!

Although hardware is important, software is even more important.

Hardware is the foundation, software is the soul.

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

"The operating system is not as good as Tianhe-[-], but we still need to develop it." Ye Feidao: "Now we replace the algorithm of the operating system with a mathematical algorithm."

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

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

"Even for Ye Fei himself, it would be difficult to do it, right? You can do it at Base 111?"

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

Supercomputers are different from home computers. Supercomputers are very technologically advanced, with complex hardware and software.

Compared with supercomputers, the technological content of home computers is one day at a time.

Home computers are like the difference between ants and elephants in front of supercomputing.

Mathematical algorithms can be used on home computers, but not sure, can be used on supercomputers.

Ye Fei said: "If you don't believe me, I can show you the number of floating point calculations."

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

Director Xu nodded, seeing that the number of floating-point calculations is not considered a technical leak.

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

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."

"Yeah!" Ye Fei nodded and said, "Turn on 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 time is long and the data is not very accurate.

Benchmark is a software used to test computing power on supercomputing. The test time is very short. Even supercomputing power can be tested in a short time.

The number of floating-point operations is less than billions of times, and it can be tested in 10 minutes.

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

"Ok!"

After 10 minutes, Ye Fei pointed to the computer screen and said, "Everyone, please take a look!"

Everyone was surprised to see that the number of floating-point operations reached 3.05 billion times.

"It's really 3.05 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. The current stage is only 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, saw Ye Fei, and excitedly said: "The computing power has broken through again."

"Breakthrough again?" Ye Fei's eyes lit up, and he asked, "How much did you reach this time?"

The experimental process is a process of continuous experimentation.

Adding mathematical algorithms to the supercomputing, Ye Fei also crossed the river by feeling the stones. Fortunately, the effect was very good.

From 1.09 trillion supercalculations, the number of floating-point operations will increase by several petaflops every time.

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

Ye Fei smiled and said, "It's okay, let's talk!"

They spoke Xia Guo dialect, those foreigners couldn't understand it, and Xia Guo people were fine if they heard it.

Besides, it's okay even if those foreigners listen to it.

Let them know the number of floating-point operations, and they will know a set of numbers at most, which is not a technical leak.

The middle-aged man said: "This time the increase is much higher, 3.2 million times, an increase of 0.15 billion times."

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

"Breakthrough 0.15 million times in a week?" At this time, an Indian in the inspection team said, "You are lying!"

This Indian can understand the Xia language.

He still remembered that Ye Fei said before that 3.05 million times was the record set a week ago, and now it has broken through to 3.2 million times, that is, it has exceeded 0.15 million times in a week.

If Ye Fei is not lying, this is too amazing.

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

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

"Oh!" Ye Fei nodded, "It's indeed a breakthrough of 0.15 billion times a week."

Those 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 astonishing, breaking through 0.15 billion times a week, God can't do it.

Ye Fei opened the computing power record chart on the computer. This chart cannot be faked. He is the background record on Benchmark.

Unless, you laboriously recreate a Benchmark, and then laboriously make a hash rate record graph in the background.

But few people do such a thankless task.

What's the point of doing it!

"Look!" Ye Fei 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 recording chart under the explanation of the others.

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

It is recorded in the graph that it only took two months for the computing power to break through from 1.08 exatimes to 3.05 exatimes.

Yes, it just broke through to 3.2 billion times.

Breaking through 2.12 billion times in two months, this is not a dream!
Yang Sili said excitedly: "This is really done by a mathematical algorithm?"

"Of course!" Ye Fei nodded.

Everyone was dumbfounded, they did not expect that mathematical algorithms could really be used in supercomputing.

And it works so well.
