From Almighty Scholar to Chief Scientist

Lin Xiao said: "Of course, maybe this calculation program will run forever. After all, no one can guarantee how long it will take to verify this problem. Maybe give me a future quantum computer?"

"I hope so," Witten said.

Suddenly he said again: "By the way, I hope to stay here for a while. Is there a problem?"

Now a month is up, and according to his original plan, he is going to leave.

Lin Xiao was taken aback for a moment, but he didn't expect that Witten planned to stay, and then he smiled and said, "Of course you are welcome, no matter how long it is."

"That's good. It seems that I can hang out in your cafeteria for a while longer."

Witten laughed, and then said: "To be honest, before I came here, I have always heard that your Huaguo Institute is not as good as our Princeton Institute for Advanced Study in terms of some systems and interpersonal relationships."

"However, now at the Dingguang Institute, I feel as if it is no different from the Institute for Advanced Study, or even better. At least in the Institute for Advanced Study, the funding problem still plagues many of our researchers, but here you are , I have seldom seen subjects that have become difficult due to funding problems in the past month, it seems that what I heard over there is all fake."

Lin Xiao was taken aback for a moment, then shook his head, but did not tell the truth, after all, family ugliness should not be publicized.

Witten's feelings are entirely because this is the Dingguang Research Institute, and he is the director, while in other research institutes, the problems Witten mentioned exist a lot.

Witten didn't notice Lin Xiao's movements, and continued to talk about other things, such as what he had seen and heard in the past month, and he also commented on the food in the cafeteria. All in all, he showed great interest.

"As long as you like."

Lin Xiao said with a smile.

However, at this moment, his cell phone rang suddenly.

He saw that it was Wang Wenguang, director of the Xishi Supercomputing Center.

Although he was a little puzzled as to why Wang Wenguang called at this time, he answered the call without thinking too much.

But before he could speak, Wang Wenguang's anxious voice came from the opposite side: "Academician Lin, what program are you running?"

There was some anxiety in the anxious voice, but also a bit of blame.

Lin Xiao was taken aback and asked, "What happened?"

"Academician Lin, the program you run with your account has created a self-test program for several nodes of our Sunway TaihuLight. These nodes are temporarily unusable. Now the system has deleted your program. Aborted!"

Lin Xiao suddenly felt unbelievable: "What? Run my program, causing Sunway TaihuLight to go wrong?"

Is his program so awesome?

Chapter 391 Pangu Supercomputer!

When Lin Xiao returned to the office and opened his Sunway TaihuLight running software, he saw a lot of error notifications popping up on it, at least twenty of them, all of which displayed [The current node is abnormal, trying to Reconnect], [Due to an error in the currently connected node, it has been automatically connected to another node] these two prompts, and there are a total of eight replaced nodes.

Until the end, the final termination notice appeared above: [Due to your abnormal behavior, the background has stopped your connection. If you want to reconnect, please consult relevant personnel. 】

The last notice clearly indicated that his internal VIP account had been blacklisted.

Lin Xiao is helpless, what's the matter?

He looked at the specific situation again, and it turned out that it was a good thing, and each node lasted for about 3 minutes.

Supercomputing is calculated by node. It does not mean that after applying for supercomputing, you can use the entire computing power of supercomputing. Unless there are some major tasks, you will use the computing power of a whole supercomputing computer to calculate a project. , usually, it is basically divided into many nodes for calculation.

For example, Sunway TaihuLight has 40960 nodes, and with so many nodes, the computing power of a single node will be less on average, while the Summit supercomputing in the United States has only more than 4000 nodes. Nodes can also achieve more computing power.

But at this point, there is really no way. Who makes the performance of the processor used by Sunway TaihuLight relatively poor?

There are two generations behind the 28nm process processor and the [-]nm process processor.

Looking at this scene, Lin Xiao frowned slightly, which was a bit unexpected. If so, how would his program run?

"Director Wang, I have seen that the procedure has indeed been terminated."

Picking up the phone again, he said.

"Oh, I see."

As for Wang Wenguang on the other side of the phone, his tone has returned to normal at this time, not as urgent as before. Probably the anxiety just now was due to a temporary accident, so his tone was a bit bad.

He said: "I'm sorry, Academician Lin, my tone was a bit bad just now, and it's because something happened suddenly."

Lin Xiao was taken aback for a moment, Wang Wenguang's tone was a bit bad just now?

In fact, he didn't notice it at all, and his attention was completely attracted by what Wang Wenguang said.

So he smiled and said, "Oh... oh, it's okay, I didn't pay much attention to it."

"That's good." Wang Wenguang sighed, and said: "Now the general reason is basically clear, mainly because the program you run, Academician Lin, is a bit too complicated, and the computing power requirements for a single node are relatively high. "

"And the nodes arranged for you are basically not capable of computing requirements, so there is this situation of entering self-inspection because it exceeds the computing power requirements."

"But to be honest, this kind of situation has rarely happened in the past. Fortunately, it has happened a few times before. We have relevant countermeasures in our maintenance system, so we are able to have problems at single-digit nodes. Even if there is a response later, if it is placed when there is no alternative plan before, I am afraid that this time will take longer."

"But even so, your program still killed several of our nodes, which is a bit unexpected."

Lin Xiao said helplessly: "This is not something to be proud of."

"Hehe, that's true." Wang Wenguang smiled, and then asked: "Then, Academician Lin, it seems that our Sunway TaihuLight can no longer help you. Do you have any plans?"

Lin Xiao said helplessly: "The light of Sunway Taihu Lake is useless, and there is no other way."

"Then use Tianhe-22. The computing power of a single node of Tianhe-86 is higher than that of Shenwei, and it may be able to meet your requirements." Wang Wenguang said: "After all, the chip on Tianhe-[-] is [-] nanometers, which is higher than that of Shenwei. It’s even higher, and it’s still an Intel chip, with an X[-] architecture, which is better than the Alpha architecture we use.”

Lin Xiao then asked: "Didn't it mean that Tianhe-[-] has always been running at full capacity? NUDT's own supercomputer can't spare nodes for use?"

"Uh... Well, it seems to be like this." Wang Wenguang said.

Tianhe-16000 does not have as many nodes as Sunway TaihuLight, only [-], so it is basically operating at full capacity. Although Lin Xiao has face, but this time he probably has to queue up honestly, after all, everyone is operating at full capacity , can't be kicked out when other people are using it, and then handed over to him for use.

Lin Xiao sighed helplessly again, this is not easy to handle.

Is it necessary to use truth points and let the system take on this supercomputing task?

But just when he was thinking about it, Wang Wenguang suddenly said, "Oh, by the way, Academician Lin, I thought of a good way."

Lin Xiao was taken aback, and said, "Say it."

"The supercomputer we are building, do you have any news about it?"

"I know, it's called Pangu. Your processor has already been designed. I heard the effect is not bad?"

This Lin Xiao naturally knows, just kidding, the funder of this new supercomputer is considered to be the money from their research, after all, Lin Xiao personally wrote the application letter, and the total investment in the end reached more than 20 billion.

"Yes." Wang Wenguang said with a smile: "Our Pangu processor, the world's most advanced 5nm process, although it still uses the Alpha structure, but in terms of chip manufacturing technology, it is enough to widen the gap with Intel."

"So I thought, maybe your program can run on our Pangu."

The Pangu processor is a new domestic supercomputing processor independently developed by Sunway TaihuLight after the Shenwei processor.

Although the manufacturing process of Shenwei processors lags behind the advanced foreign manufacturing processes, it has already proved that their domestic chip designers have good enough chip design capabilities. In the field, the abilities of Huaguo talents are often reliable.

Therefore, the Pangu processor can already be called the best supercomputing processor in the world.

Coming from the most advanced 5nm process, it is enough to make the Pangu processor so honorable.

Of course, these are currently known information, but Lin Xiao still feels a little puzzled about Wang Wenguang's proposal: "Is it the Pangu processor? But it doesn't mean that it hasn't been built yet?"

Wang Wenguang smiled and said, "It's completely built, but it doesn't affect running a program first."

"Next week, we will build the first batch of five computing nodes. At that time, in order to test the performance of these processors, we will also use them to run a few programs. It's like a new computer baking machine. , Academician Lin should also know, now that your program can't even withstand our Sunway TaihuLight, maybe it can give full play to the full performance of our first batch of nodes?"

"How about it?"

Hearing Wang Wenguang's proposal, Lin Xiao immediately said, "Of course there is no problem."

He can not only test their processor, but also solve his problem. Of course, he has no reason to refuse such a thing that kills two birds with one stone.

"Okay, then wait until next week, Academician Lin, come to our Pangu Supercomputing Center, and then, come and test it yourself."

"Row."

……

Time soon came to the second week.

Lin Xiao came to the Pangu Supercomputing Center with a USB flash drive.

Although the Pangu Supercomputing Center is not located in the city center, it looks quite impressive from the outside. After all, it is called Pangu, so it is nice to have a bit of style.

When he came here, Lin Xiao met Wang Wenguang and other related personnel, including Kong Huaan.

Today, Kong Huaan has become an important technical figure in the Pangu supercomputer team, serving as an important technical staff member in the processor architecture team.

Regarding Kong Huaan's development track, Lin Xiao can only say one thing besides emotion, probably this is a real genius, who can leap from a CMO gold medal in mathematics to a master in the computer field , and even now has become an important member of the national supercomputer project, this kind of span, I am afraid that it is also a cheating life.

Of course, Lin Xiao didn't say too much about these things, just saying hello, and of course there is not so much to say about good friends.

Then, they went directly to the computer room, and Lin Xiao also inserted the USB flash drive into the computer.

"Okay, now it's ready to run. Check if the power supply is all right. This is the first time our Pangu processor has run such a computationally intensive program. Let me check it out."

Wang Wenguang directed the inspection of the staff.

Soon, everything will be ready.

Wang Wenguang directly issued an order: "Start running the program!"

As the staff sitting in front of the computer pressed Enter, a moment later, there was a violent sound of wind in the cabinet in front of them.

That's exactly what a fan sounds like.

Pangu Supercomputer uses a combination of air cooling and water cooling for heat dissipation. For processors with a 5nm process, heat dissipation is very important.

And on the screen in front of him, a lot of data was flashed in an instant.

At the same time, these data also include the current computing power, average computing power, and peak computing power data!

Looking at the data, the staff next to him were stunned: "The average number of floating-point operations per second of a single node... 512TFLOPS! Is... so powerful?"

And the other people around looked at the result, and they were already stunned.

512TFLOPS!

It is nearly five times that of a single node of the world's fourth-ranked Summit supercomputing node in the United States!

What is the concept of five times?

Everyone present is very clear, which means that they only need the same number of nodes, and the total computing power can easily exceed Summit by nearly five times.

However, the total number of nodes they plan is [-]!

It is almost equivalent to three times the nodes of Smmit, which means that the total computing power will be fifteen times that of Summit!

And the world's number one supercomputer on the border of the United States, the total computing power is only about seven times that of Summit, and there is still a gap of more than two times!

At that time, all the supercomputers in the world, not to mention their backs, may not even be able to see their backs.

"We, are we creating a myth?"

Someone couldn't help but exclaimed.

And Wang Wenguang also recovered from the shock at this time, and then said with a big laugh: "We are creating a myth, it is called Pangu, isn't it just creating a myth?"

The people present couldn't help laughing when they heard it. These words are quite reasonable. Isn't Pangu just a myth?

Suddenly, these supercalculators were all happy about it.

After all, the world's most unrivaled supercomputer will be born in their hands, how can they not be excited about it?

Of course, except for those very happy people like them, Lin Xiao was staring at the other side, which was the calculation of his program.

This time, the Pangu processor successfully resisted the huge demand for computing power of his program, so how long will it take to complete?

Lin Xiao will wait and see.

Chapter 392 Unified Relativity and Gravitons!

In the next few days, Lin Xiao paid close attention to how his program was running almost all the time.

At the same time, the good news about Pangu's supercomputer was not hidden, but announced directly.

After all, with such a good thing, you can tell your superiors that the more than 20 billion they spent is real, and in terms of cost performance, their more than 20 billion is still worth it.

The original Tianhe-3 cost [-] million US dollars, equivalent to a quarter of the US Summit supercomputer, and their Pangu supercomputer will cost more than [-] million to nearly [-] million US dollars, equivalent to [-] Summits, and more than two The frontier supercomputer, and the cost of the frontier supercomputer, is as high as [-] million US dollars.

This price/performance ratio is completely full.

And in addition to expressing to the above that there is no waste of money, they can also announce to the world that their supercomputer can become the number one in the world without any suspense, and the same is true for their processor.

The average computing power of a single node is as high as 512TFLOPS of floating-point operations, which almost directly announced that the Pangu processor has been directly promoted to the throne of the most powerful supercomputing processor.
