Yan An acquiesced to their protection, even if he wanted to refuse this kind of thing, Gao Shenghan and they would not agree.

Unless he goes to the Regency or Zaras, but these two countries are not much better, maybe they will go even further, directly from long-distance security protection to 24-hour close protection and surveillance.

Hung up Gao Shenghan's phone, Yan An thought for a while and sent a message back to BT.

Thinking that he and BT are now "face-to-face" but still have to communicate in this way, Yan An is a little helpless, and now he only hopes to get the platform code of the cloud service as soon as possible, so that he can let BT complete a wave of small upgrades.

After confirming that these four people were not thieves but members of Zhu Chi's official body who came to protect Yan An, BT relatively relaxed its monitoring of them.

The four soon received a call from Gao Shenghan and were told that they had been discovered by the protection target.

When they first heard the news, they were still at a loss, and this was discovered?

At that moment, Wang Zhifang had deep doubts about his professional skills, whether he was usually too slack so that he couldn't even do his job well at a critical time.

When he knew that he was exposed because of surveillance, he didn't know whether to praise or scold so much surveillance on this street.

In short, the next work was easy but extremely depressing, and the subject of protection already knew that they existed, and then did the same activities as before, so that he always felt that he was a perverted tailgating.

After Yan An returned home from the shop, he saw that it was still early, so he reviewed the dimensional phase factor factorization algorithm again to deepen his mastery, and by the way, he gave the method used to solve the large integer factor factorization problem on the Blue Dome.

Yan An has memorized common solutions such as the continuous fraction method, Pollard algorithm, and secondary sieve method, but there is still a long way to go to be able to use the distance proficiently.

Different methods have obvious advantages and disadvantages, although they can also be used to solve large integer factorization problems, but they all have a disadvantage that cannot be ignored.

That is, when the factor is a safe strong prime, the time required to solve the computation is much longer than the validity period of the cryptosystem.

Similar to using a quantum computer to crack RSA, theoretically there is no problem at all, but in practice, at the current level of development, it takes 70 years to crack a code, which can be said to be meaningless.

After a simple study, Yan An went to sleep.

He didn't plan to study these methods in depth, because no matter how much they were improved, the ultimate goal was to solve factor factorization, and he had already mastered a method of factorization, so there was no need to waste time on it.

Early the next morning, about an hour after Yan An woke up, there was an unexpected knock on the door.

Standing outside was Gao Shenghan, "I heard from the comrades of Guoan that you usually get up at six o'clock, so I thought that Sunday might be the same." ”

He was worried that it would disturb Yan An's rest, but seeing that he seemed to have washed up, he knew that his worries were unnecessary.

"It's Sunday, aren't you resting?" Yan An is a little strange, in his stereotype, the state unit has always been a quiet day on Friday and Tuesday, and he thought that he would not officially start work until Monday.

"I'm afraid that's not what you think, in fact, our working hours are very flexible." Gao Shenghan was a little helpless, if the project was not tight, they could also take five days off and two days off, except for special circumstances.

Recently, for example, they have implemented a flexible work system, and this flexibility is still very strong, for several days.

Yan An didn't have any feelings about starting work on Sunday, if he could be the leader, in order to return to Mingxing as soon as possible, he would be happy to fix his flexible working hours to work twelve hours a day, all year round.

"Is the supercomputing cloud thing done?" Yan An asked a question he was most concerned about at this stage.

"I'm here to pick you up." Gao Shenghan smiled smugly.

No matter what shocking technology he came up with, his vision seemed to be at the level of an ordinary normal college student, and the supercomputing cloud might be the best treatment he could imagine with all his might.

However, for such a genius and such a major project, the use of cloud services is too much.

"Cloud services are inconvenient after all, and the efficiency of computing power utilization is too low, and even the top algorithms can only use about 40% of the computing power.

We are worried that the computing power after the loss will not be able to meet the needs of cracking, so after discussion, we simply borrowed the computing center of your school, if the computing power is still not enough, it is no problem whether to upgrade directly in situ or borrow a better one. ”

"......" noticed that Yan An's expression was a little slight when he didn't speak, and thought that he was shocked by this hand, which made Gao Shenghan very satisfied.

It's been a few days, and I finally showed my muscles, which made this kid startled.

He didn't know that Yan An was helpless in his heart.

Why do you want to supercalculate, can it be faster than BT?

According to the computing power of BT at the lowest power consumption, 20 quadrillions per second far exceeds the average level of today's Blue Dome supercomputing, even if it is not much lower than the "apex" of the first place on the list and the regent country, and it can be easily surpassed by slightly increasing the power consumption.

Moreover, the demand for computing power of the factorization algorithm is not so high, even the dynamic ellipse factorization algorithm with the highest demand for computing power requires only 300 trillion calculations per second.

What's more, he chose the dimensional phase factor factorization algorithm with the lowest demand for computing power, according to yesterday's experiment, the computing power required to complete this algorithm is only 21 trillion times per second at most, even if the cloud service can only use 40% of the computing power, it is enough to complete the algorithm.

What's more!

Without a cloud service platform, he can't copy.

There is a finished product transplanted to BT and there is no finished product to do it yourself are two different things, although the former will be unrecognizable after the modification and modification of the entire platform, but there is a framework to do the basic. The latter is completely starting from scratch.

"Enough...... Can't you use cloud services? He really didn't know how to explain to Gao Shenghan that he didn't really want computing power, he just wanted a platform.

"It's not better to use it directly, and it's too wasteful of computing power to say cloud services."

"Then don't you still have to count the east and the west? Isn't that also using cloud computing, how to and this don't worry about computing power loss. ”

"The situation is different, even if the supercomputing center is located in the east, it is still using cloud services to provide computing power, and advancing to the west is conducive to the national integration layout, optimizing resource allocation, and improving resource use efficiency."

Supercomputing, after all, is not a one, the data is received from the outside world and processed by cloud computing, if only a certain type of data in a certain place is specially made a supercomputer, it will not be long before they can hear the cry of the power system.

“…… But I still want to. ”
