Chapter 60: Being two years older is not a problem
National Computer Engineering Center, Supercomputer Center.
Four years ago, this place was still very busy, with staff working three shifts and working around the clock.
Because the first-generation Sunway computer had just come out at that time, the country's top universities and research institutes were all lining up to compete for supercomputer time.
But by 2004, it was no longer busy here. The Sunway generation supercomputer with 384 billion operations per second could no longer keep up with the times.
The Galaxy supercomputer at the National University of Defense Technology reached a calculation speed of one trillion times per second three years ago. It is definitely faster now. As for the specific speed, it is a military secret.
The Sugon 4000 supercomputer launched by Sugon in 2004 can run at 4.2 trillion times per second. It is said that the Sugon 4000A with 10 trillion operations per second will appear in 2004,
Even Lenovo Group, which assembles computers, has built a Shenteng 6800 with 5.3 trillion operations per second.
With so many supercomputers with faster computing speeds, the business of the Sunway generation is naturally much less.
So what is the concept of the 384 billion calculations per second of the Sunway generation?
At that time, the top-of-the-line Intel Pentium 4th generation processor had a computing speed of 2 to the 30th power, which was approximately 1 billion operations per second.
The computing speed of the Sunway generation is 384 times that of the Pentium 4 top version!
In other words, if a top-end home computer takes three days and three nights to calculate the Mersenne prime number M24,036,583, then a Sunway supercomputer can complete the calculation in only 10 minutes. .
The last person to use the Sunway supercomputer today used it for nearly half an hour longer than the declared usage time.
This is definitely not in compliance with the regulations, but the other party wisely stuffed two packets of Chinese into the pocket of the programmer on duty.
The programmer touched his pocket and said, "Hey, the gift from Zhonghua this time is not toothpaste, so happy!" He happily allowed the customer to use the supercomputer for an extended period of time.
After the customer who sent Zhonghua left, the programmer stretched and then remembered what the leader had told him to verify whether a number was a Mersenne prime.
Taking out the small note given by the leader, the programmer took one look at it and laughed contemptuously.
As a programmer, of course he knew about the GIMPS project conducted by the United States in order to find Mersenne prime numbers. At that time, he also downloaded the prime95 program and tried it, but his computer crashed.
"Messenne primes? How is it possible! From 1996 to now, in eight years, only 6 Mersenne primes have been found. It is not certain whether there will be a next Mersenne prime!"
After inputting M24, 036, and 583 into the computer, the programmer took out a magazine and read it with relish.
I don’t know how long it took, but when he looked up, he found that the supercomputer had completed the calculation.
The results show that this is a prime number!
“Dear me, it’s really a Mersenne prime!”
……
"Dad, I'm going to school!" Zhuge Ruoruo shouted into the living room and walked out.
Professor Zhuge subconsciously walked to the balcony window and watched his 170-year-old daughter disappear from sight while riding a bicycle.
“If Ruoruo is a junior in college now and will be a senior in the summer, it’s time to find a partner based on her age! If she waits until she is 25, she will be a leftover girl and it will be difficult to get married!”
Professor Zhuge thought of several young talents, all of whom were relatively well-known graduate students at Tsinghua University.
Eventually, Zhang Wei also appeared in Professor Zhuge's mind.
"Although Zhang Wei is not outstanding, he is over 1.8 meters tall, which matches Ruoruo well. And with that graphene, he may win the Nobel Prize in the future.
He is just older than mine. Ruoruo is two years younger. By the time he graduates, Ruoruo will be almost 30 and will become an old girl! No, it’s still inappropriate! We need to find someone older.”
Just like Professor Zhuge. While I was silently choosing my son-in-law, my cell phone suddenly rang.
"It's the number from the Computer Engineering Center. By the way, I asked them to verify that number yesterday!"
Professor Zhuge is also very busy. If it hadn't been for this call, he might have called I forgot about the Mersenne primes. "Hello, I am Zhuge Xuegeng. The results are out? Is it really a Mersenne prime number? There are 7,235,733 digits in total. Is it the largest Mersenne prime number discovered so far?"
For a moment, Professor Zhuge’s mind went blank.
New Mersenne primes discovered! And it’s also the biggest one!
This means that the Algorithm Society will receive an update, and all keys around the world will also be upgraded!
“Zhang Wei really found a new Merlin prime number! He just made graphene two days ago, and not long after that, he found a new Merlin prime number! He is only nineteen years old, This is the result! ”
Professor Zhuge finally recovered his thinking. He watched his daughter riding her bicycle away from the direction and clenched his fists slightly.
"Isn't it just two years older? It doesn't seem to be a problem!"
......
Principal Gu has just come back from a meeting outside, and his butt is still hot. , Professor Zhuge came to the door.
"Principal Gu, there is something I need to report to you about Zhang Wei!"
"Isn't Zhang Wei's matter already settled? He has to go back and repeat his studies. We can't force people to go to college! We should follow his personal ideas."
Principal Gu paused for a moment, then continued Said: "I know, you want Zhang Wei to go to your Department of Mathematics, but you are not the only one who thinks so. Lao Shen from the Department of Electronics, Lao Wu from the Department of Materials, and Lao Fang from the Department of Physics, who doesn't want Zhang Wei to go there?
And Zhang Wei’s research result is graphene, which has nothing to do with your mathematics department! Why did Zhang Wei come to your place to care about your age?”
"Maybe she's trying to show off my daughter's 170cm tall legs!" Professor Zhuge smiled slightly and then said: "Principal, this is not what I want to report to you. Look at this!"
Zhuge The professor said and handed the number M24, 036, 583 to Principal Gu.
Principal Gu put on his reading glasses, looked at it carefully, and said, "Is this a Mersenne prime number?"
"Yes, I just discovered it, the 41st Mersenne prime number!"
"I said Zhuge, if you want to start a new scientific research project, you have to go through the formal process and get approval from the school. It's no use asking me!"
Principal Gu thought that Professor Zhuge wanted to do this. Applying for a new scientific research project came through the back door.
"Principal Gu, this 41st Mersenne prime number was discovered by Zhang Wei! Just yesterday!"
Principal Gu's expression was stunned: "Zhang Wei discovered a new Mersenne prime number? Are you not mistaken? Isn't his scientific research direction graphene? Why is it related to Mersenne prime numbers again?"
Graphite From alkene to Mersenne primes, the span is a bit big.
This is probably like a top excavator driver winning the World Pastry Chef Competition.
"Principal, I am also surprised! But this Mersenne prime number was indeed given to me by Zhang Wei!"
"Has it been verified?" Principal Gu asked.
Professor Zhuge nodded: "It has been verified and used divine power."
Divine power? Uchiha Obito said, I am familiar with this trick!
Professor Zhuge continued to look at Principal Gu with expectant eyes, and then asked: "Will this result be published?"
"Fat! It must be published!" Principal Gu did not hesitate. said.
"Then send it in the name of Zhang Wei, Department of Mathematics, Tsinghua University?"
Only then did Principal Gu realize that Zhuge came here specifically to get this name!
"If Zhang Wei has no objection, then let's do it!" Principal Gu nodded.
The resurrection was successful. I will continue to recommend next week. Thank you for your support! However, the road is long and long, and there are still three rounds of PK. Only with good results will you have the opportunity to go to Sanjiang. I hope you will continue to support me. Thank you very much!
