Base 111, Laboratory 1!

"Researcher Ye!" A research intern said, "This involves P=NP, what should I do?" ”

Ye Fei's position in the supercomputing center is a researcher.

Ye Fei said: "Use NP Turing completeness!" ”

There are eight major problems in mathematics, also known as the millennial problem.

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

Among them is P=NP, which is also a problem in the field of computing.

NP Turing Completeness!

It's complicated to explain, so don't explain.

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 predict the future, just like God, and the spiritual world of human beings will be completely satisfied.

Like artificial intelligence, VR, astronautics, shuttling through parallel worlds, sci-fi events that can be imagined, can be realized.

The coolest thing is that artificial intelligence can be tailored to provide you with all the needs you thought of and did not expect according to people's psychological and physiological needs.

The intern said, "What exactly are you referring to?" ”

Ye Feidao: "Recursive realizable classes composed of recursive sets, interstitial languages, and hysteresis diagonal methods. ”

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

Ye Fei turned off his mobile phone when he was working, but today because of something, he turned on his mobile phone.

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 in the supercomputing center, only manages administrative management, and mainly does some miscellaneous things.

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

These things are all handled by Director Xu.

For example, in the reception of today's multinational delegation, he had to accompany him throughout the process.

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

After Ye Fei saw the information, 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 below, no problem!" ”

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

Half are Asians, three are Indians, and seven are Europeans.

Ye Fei nodded and said, "No problem." ”

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

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

Immediately, he led everyone to the 111 base.

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

Ye Fei glanced at him, and Director Xu whispered on the side, "He is Kono Yoshihuai of Dongying Kingdom." ”

Ye Fei said: "Three hundred million times." ”

"Three hundred million times?" A middle-aged man wearing glasses said suspiciously: "I remember that the number of floating-point operations in the Dune Supercomputing Center is 109 million billion!" ”

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

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

Ye Fei said: "It is true that it used to be 109 million times, but we also have to make progress, it is impossible to stand still, a week ago, our computing power has broken through to 300 million times." ”

"It can't be!" Kono shook his head and said, "I also came here two years ago, when your floating-point operations were still 109 million billion. ”

"Can you add 200 million times in just two years?"

Ye Fei said: "How is it impossible to increase 200 million times in two years? In 2010, the number of floating-point operations on Tianhe-1 was 257 million, and by 2015, the number of floating-point operations on Sunway Taihu Light reached 1.254 billion times. ”

"A billion more times in five years."

"We've added 200 million times here in two years, it's not an exaggeration!"

Kono said: "The reason why the number of floating point operations of Shenwei Taihu Light is so high is because of hardware reasons. ”

"And Dune's supercomputer, although the hardware used is the same as Tianhe-1, the operating system is not as good as Tianhe-1."

Supercomputing values hardware, but also software!

While 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-1, but we also need to develop it." Ye Feidao: "Now we are replacing the algorithm of the operating system with mathematical algorithms. ”

"Math algorithms?" Kono sneered: "Is it the algorithm created by Ye Fei? Can it be applied to supercomputing? ”

"It's not a home computer, it's a supercomputer."

"Even if it's Ye Fei himself, it's difficult to do it, but you can do it in the 111 base?"

The rest nodded, yes, this is supercomputing.

Supercomputing is different from home computers, supercomputing is very high-tech, and the hardware and software are very complex.

The technological content of home computers, compared with supercomputing, is one day at a time.

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, and they can be used for supercomputing.

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

Ye Fei looked at Director Xu beside him, he didn't know whether he could do this, so he still had to ask Director Xu.

Director Xu nodded, looking at the number of floating-point operations is not a technical leak.

They just see a set of numbers, and the code of the operating system doesn't see it.

Ye Fei led everyone into the computing power test room.

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

"Hmm!" 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 applied to test computing power on home computers, and the test time is long, and the data is not very accurate.

Benchmark is a software that is used to test computing power on supercomputing, and the test time is very short, even if it is supercomputing power, it can be tested in a very short time.

Floating-point arithmetic is within billions of billions of times, and it can be tested in ten minutes.

The number of floating-point operations is less than 10 billion times, and it is tested in an hour.

"Okay!"

Ten minutes later, 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 305 million times.

"That's 305 million times!" The crowd exclaimed.

"Is this really mathematically calculated?" Yang Sili asked.

The rest of the people all looked at Ye Fei.

Ye Fei nodded: "It is indeed done by mathematical algorithms, this stage is only our experimental stage, and 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 said excitedly: "The computing power has broken through again." ”

"Breakthrough again?" Ye Fei's eyes lit up and asked, "How much has it reached this time?" ”

The process of experimentation is a process of continuous experimentation.

Mathematical algorithms were added to supercomputing, and Ye Fei also crossed the river by feeling the stones, fortunately, the effect was very good.

From 109 million supercalculations, trillions of floating-point operations are added every once in a while.

The middle-aged man glanced at the people in the inspection group with a hesitant expression.

Ye Fei smiled: "It's okay, let's say it!" ”

They speak Xia dialect, and those foreigners can't understand it, and it's okay for Xia people to listen to it.

Besides, even if you let those foreigners listen, it's fine.

Let them know the number of floating-point operations, and they will know a set of numbers at most, 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 15 million times. ”

"So much!" Ye Fei smiled: "Not bad! ”

"More than 15 million times in a week?" At this time, one of the Indians in the delegation said, "Liar! ”

This Indian can understand Xia Guohua.

He still remembered that Ye Fei said before that 305 million times was the record a week ago, and now it has broken through to 320 million times, that is, it has exceeded 15 million times a week.

If Ye Fei didn't lie, this would be too amazing.

"Huh?" The Xia people present all stared at the Indian, and Ye Fei asked, "Can you understand the Xia country?" ”

Indian: "I went to college in Xia Kingdom. ”

"Oh!" Ye Fei nodded: "It is indeed more than 15 million times a week." ”

The people present who could understand Xia Guo's dialect all looked at Ye Fei in surprise.

"Impossible!" Professor Yang Sili was stunned and said, "How is this possible! ”

It's amazing, breaking through 15 million times a week, and God can't do it.

Ye Fei opened the computing power record chart on the computer, this graph cannot be faked, he is the background record on Benchmark.

Unless, you go to great lengths to recreate a Benchmark and then work hard to create a hashrate record in the background.

But few people do this thankless task.

What's the point of doing it!

"Look at it!" Ye Fei said: "This is our breakthrough in computing power in the past two months. ”

The people present who couldn't understand Xia Guo's dialect, under the explanation of the rest of them, all looked at the computing power record map.

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

According to the chart, the computing power broke through from 108 million to 305 million times in just two months.

Yes, it has just broken through to 320 million billion.

It has exceeded 212 million times in two months, this is not a dream!

Yang Sili said excitedly: "This is really done by mathematical algorithms??" ”

"Of course!" Ye Fei nodded.

Everyone was dumbfounded, they didn't expect that mathematical algorithms could really be used in supercomputing.

And it works so well.
