Chapter 43: The Bottleneck
Wang Shouren is very interested in Wang Yinan's brother doctor, "I thought my brother doctor was a foreigner, but I didn't think it was an artificial intelligence", Wang Shouren said, "Many teams have also asked me to cooperate in the development of computer programs for TCM assisted diagnosis".
"Among them, there are also high-tech projects such as Huaguo's 683, but when they get the classics of traditional Chinese medicine, they often have a feeling that the mouse pulls the turtle and has no way to start."
"Most of them end up spending a lot of money in vain, and they still end up with nothing."
"Your idea of black box analysis is very good, so it avoids a lot of difficult theoretical problems"
"It's not my invention, Mi Ge used this idea when he played Go, and now Mi Ge's Go dog can make the world two sons," Wang Yinan said.
The more the two talked, the more speculative they became, Wang Yinan also wanted to take the opportunity to make friends with this Chinese medicine national hand, the current brother doctor has a lot of shortcomings in independent consultation, but if it is used as a supplement to experienced Chinese medicine doctors, it can definitely play a role where one plus one is greater than two.
was chatting happily, Deng Ruoyan came over, "Wang Lao, a man", "My grandfather is awake, please go and see it again".
The two came to Deng Lao's bedroom, Deng Lao had already sat up by himself, leaning on the head of the bed, looking much better, seeing them come in, Deng Lao nodded and said, "Wang Lao is worthy of being a great master, the medicine is cured, I feel much better, please let Wang Lao take a look."
Wang Shouren stepped forward, "This time, thanks to a boy's reminder, the old man doesn't dare to take credit."
"It's a shame to delay Deng Lao's illness for a few days."
After speaking, Mr. Wang seriously helped Mr. Deng take the pulse.
Obviously, Deng Lao only knew that he had eaten Wang Shouren's recipe, and he didn't know Wang Yinan's stubble, so he looked at Deng Ruoyan's father with an inquiring eye.
"Here's the thing, the amount of several flavors of medicine in Wang Lao's prescription is debatable, and it just so happens that Wang Yinan, who was invited by Ruoyan, is also quite insightful about Chinese medicine."
"He discussed it with Wang Lao, and then adjusted the prescription, and now it seems that the effect is still good."
Okay, Wang Yinan became a child all of a sudden, but look at the big guys in the room, children are children, it seems that this level has finally passed.
Wang Guo's hand gave Deng Lao the pulse, "basically no big deal",
"You can drink some porridge appropriately, the dose of this recipe is halved, and you can take another dose after meals."
Old man Deng recovered from a serious illness, drank some porridge and soon fell asleep again, Deng Ruoyan's father wanted to go back to the government to work, and Deng Ruoyan was responsible for sending them back.
Wang Yinan looked at the familiar company building, touched the clothes on his body, and seemed to be soaked, although it was less than a day, it could give him a stimulus, which he usually couldn't touch once in ten days and a half months.
"Even if there are sisters' tears in the future, this kind of high-risk thing still can't be done", although recalling Deng Ruoyan's grateful and relieved look when they separated, Wang Yinan still had a little excitement in his heart, but he still secretly made up his mind,
"A gentleman does not stand under a dangerous wall, this is the right reason."
Doctor Brother is a little out of the limelight this time, but there are also many problems, if Wang Shouren could not have made up his mind to modify the prescription he prescribed according to Doctor Brother's suggestion, things would not have gone so smoothly. Wang Yinan decided that he couldn't let his brother doctor come back in the future, but Wang Yinan also told Wang Shouren that if there is an incurable disease, the brother doctor can help him make a reference for mutual benefit.
Anyway, this time it can be regarded as a safe pass, and it also sold the favor of the old Deng family, except for Li Wenjing's face for a week after that, things are quite successful.
Not everything went smoothly, and the study of superconductivity theory seemed to have reached a dead end. Wang Yinan and Li Wenjing proposed a new lattice model that can well simulate many behaviors of oxides in the low temperature region, but for more than three compounds, this theory is powerless.
"Once the number of compounds is increased to three, our lattice model will appear infinite at many points", although he usually does not give Wang Yinan a good face, but when working, Li Wenjing still has a clear look.
"What about the use of renormalization techniques in quantum mechanics?" , Wang Yinan said,
"No, press the gourd and raise the scoop, often correcting an infinity, and a new infinity will appear"
"Could it be that there is something wrong with our lattice model?" Li Wenjing was a little skeptical.
"No, judging from all aspects of performance, this model should be very close to the real model hidden behind it," Wang Yinan said.
"I have a hunch that as long as we solve this infinite problem, we will definitely make breakthroughs."
"The problem is that I don't have a clue at all."
Wang Yinan is also worried, the current lattice model formalization work has also been completed, he and Li Wenjing also tried to use the Gödel system for analysis, but every time the analysis is carried out to a certain extent, it will fall into a dead loop, and once it also leads to the logic of the Gödel system disorder, if it is not cut off in time, I don't know what will happen.
It seems that if you want to make a breakthrough, you still have to focus on the Gödel system, Wang Yinan summoned Sun Wei, Zhao Tiancheng and Li Fei held a discussion meeting, and Li Wenjing and Zhang Qi also participated in the discussion.
"I remember that we had a meeting last time to discuss the performance improvement plan of the Gödel system, and we still follow the order of the last time, Wen Jing, you can first talk about whether there is any new progress in theory", Wang Yinan made a simple opening remarks.
"According to the idea of the last meeting, the recent work of the theory group has mainly focused on mapping the real system into the formal theory of the theoretical space, and we have made great progress in this regard," said Li Wenjing.
"This is reflected in the 116 Institute, as well as in the latest lattice models, and we now have a much shorter time to formalize the reality system into Gödel's neural network, and the realism is greatly improved."
"But in terms of performance, there's not much we can do",
Wang Yinan had expected this, "Well, the formal theory has now been very unexpected."
"Let me talk about the work of the software part, the main bottleneck at present is still the search and matching of multi-dimensional space, when we restore the Gödel system, we have also made some optimizations to the previous overall architecture, and now the support for heterogeneous systems has been greatly strengthened, and we have also put most of the routine work on the CPU or GPU to reduce the pressure on the FPGA as much as possible."
"But if you want to improve performance, you have to fall on Sun Wei, Sun Wei, you can talk about it", Wang Yinan said to Sun Wei.
"We have used the Gödel system to carry out many iterations of the FPGA circuit, and when there is enough performance improvement after the iteration, we will replace some FPGA chips in grayscale, in fact, some of the FPGA chips of the Gödel system are already the fifth generation."
"But the recent iteration has been difficult to get a performance boost, and the performance gain from adding FPGA chips is extremely small."
"In fact, it's too small to be worth it."
"In other words, the road to improving the performance of Gödel's system through hardware has almost come to an end."
Sun Wei's words caused the conference room to fall silent for a long time. As a senior hardware expert, his judgment is quite credible, that is, unless a new solution can be found, otherwise, no matter how much money Wang Yinan invests, there will be no way to improve the performance of the Gödel system.
"Is there a way to improve the cooling efficiency of the cooling system and then overclock it?" , Li Fei is a senior DIY player, and his computers are all overclocked, so he naturally thought of overclocking.
"No, the performance improvement obtained by overclocking is already limited, and the risk is too great, in case the chip and board are burned out, it is too late to cry", Wang Yinan immediately rejected the proposal.
"Does the supplier have any new FPGA equipment, and can it improve the performance of the dedicated circuit," said Zhang.
"Manufacturers do have some new FPGA equipment, but they are not mature, and the performance improvement of the FPGA itself has also entered a bottleneck period, between the two generations of FPGA chips, the performance is increased by less than 20%", Sun Wei said, "but in the case of last resort, it can be used as an alternative."
Seeing that the breakthrough is in front of him, but separated by a thick wall, this taste is really uncomfortable, Wang Yinan envy those who open a golden finger or bring their own system, MD, this is not scientific, how can the system be omniscient and omnipotent, there are problems, ask the system, encounter readers who suspect something, a sentence of alien technology will be dismissed.
is also the protagonist, why am I treated so poorly, I am afraid of revealing a TCM prescription, "Author, you come out, I promise not to kill you".
Wang Yinan was complaining, the phone rang, it was Deng Ruoyan,
"Yinan, is there something wrong at night", Wang Yinan wanted to say that there was something, but when the words came to his mouth, he made the mistake of weak legs when he saw a beautiful girl, "It's okay, it's okay, even if there is something, Miss Deng has instructions, isn't that a sentence."
"So some people are born with a lack of flatness, if I were Li Wenjing, I would also shave him with big ears", Zhang Qi complained secretly on the side.
"There is a cocktail party in the evening, there are many friends in the investment circle and the IT circle, I think it may be of some use to you, can you come, call Li Wenjing, just where I ate roast duck last time",
Wang Yinan thought to himself, this meeting can't go on now, it's good to change his brain, but seeing Li Wenjing's ears pricked up on the side, Wang Yinan began to stutter again,
"Cocktail party, you know I'm a countryman, not suitable for this kind of occasion", Wang Yinan said with difficulty, "Forget it."
"Qian Zhonghua will also come, he asked me to call you, or let him call you directly?" , Deng Ruoyan's voice is still so gentle and polite.
Okay, okay, two-to-one, Wang Yinan made a simple vote in his head, "Well, then I'll take a look"
"Let's go back and think about it, let go of our thinking as much as possible, and don't be limited by what we have," Wang Yinan said to everyone.
"I believe that this is the last hurdle, and if you get past it, you will be able to get through."
The meeting ended hastily, Wang Yinan went to call Li Wenjing, and naturally gained a look of contempt and white eyes.
"Love to go by yourself, this girl doesn't have the time to accompany you to pick up girls",
"This is for the development of the company, and it is definitely beneficial to meet investors and friends in the IT circle," Wang Yinan explained.
"Come less, I'm not going to go anyway", Wang Yinan didn't want to think about it, it was good for people to smoke him with a small ear, and he wanted Li Wenjing to accompany him.
After grinding for more than an hour, Wang Yinan still had to go alone, he took a taxi, and he didn't pack up, so he went to the small alley in Xicheng.
