"The original weather simulator was big and very computationally demanding, and I usually ran or optimized it on a machine in the lab. It's just a simplified version, but their algorithm is pretty much ......"

Lou Bingcheng opened the simulator while introducing.

I saw that on the screen was a program with a very simple interface, among which there was a rough map of the world, which was basically gray, only in the location of the capital of China, there was a little color.

"The meteorological monitoring points in the capital of China are relatively dense, so I usually use the meteorological data of the capital to simulate or adjust. ”

Lou Bingcheng clicked "Import" in the window on the left side of the rain simulator, and after the progress bar was finished, a series of parameters in the window below began to flash rapidly, and the color of the map of the capital also changed.

Lou Bingcheng said: "What has just been imported is the basic meteorological data of the capital in the previous month...... For each quarter, the simulator has a theoretical model of climate change. ”

"In this way, even on a personal computer, it can still maintain an accuracy rate of about 75% in weather forecasting, and about 20% accuracy in rainstorm forecasting. ”

Soon the simulator will give the weather forecast for the capital for the next week, including rain and rain, temperature, precipitation and so on.

Lou Bingcheng clicked on the "comparison" next to it again, and then the result of "72%" was displayed on it.

"This is a comparison with the forecasts released by the Capital Meteorological Bureau, and sometimes there are big differences," he explained. But after a long period of summarization and induction, those two figures are basically accurate. ”

Lin Han nodded slightly: "If this simulator runs on a mainframe, how accurate will it be?"

Lou Bingcheng lifted his glasses: "I have run on the mainframe a few times, and the accuracy rate of weather and rain is about 85%, and the accuracy of rainstorm prediction is 22%......"

Although this accuracy rate is slightly lower than that of the Meteorological Bureau, after all, the simulator developed by Lou Bingcheng alone is already quite an excellent achievement.

This result is not far from Lin Han's original idea, and it should be enough to achieve the expected goal under the condition that the machine and data conditions are more superior.

"Dr. Lou, let's talk about the details of the cooperation. ”

……

A few days later, Lin Han and Lou Bingcheng took a plane from Canberra to the capital of China.

Lou Bingcheng's academic visit has been basically completed, but the nominal deadline has not yet expired, and he communicated with his supervisor and returned to China ahead of schedule.

When he came to the capital, Lin Han first followed him to Tsinghua Fork Courtyard to see this academic highland that he used to yearn for, and he was fortunate to meet Mr. Yao Qizhi, who can be called the Taishan Beidou in the computer science industry.

Academician Yao Qizhi learned of the plans of the two and expressed his support, hoping that the two could make some pioneering contributions in the field of meteorological services in China.

At the end, Academician Yao also said that if there are any technical difficulties, he can also provide some help and theoretical references within his ability.

Lin Han was naturally happy to do this. Although Academician Yao is a theoretical scientist, after all, he is a Turing Award-level existence, and his scientific research experience and theoretical perspective are absolutely unattainable by ordinary people.

What's more, there is also the Turing Award, which is comparable to the Nobel Prize, and when the company is established, even if it is just an introduction to a paragraph "world-famous scientist, Academician Yao Qizhi has instructed our company's technology...... it must be excellent.

……

IBM Chinese translation name "International Business Machines Corporation", or "International Business Machines Corporation", is one of the world's most famous technology companies, in the business machine and computer underlying achievements, unparalleled,

Lin Han once discussed with others, regardless of market value and income, which IT giants such as IBM, Google, Microsoft, and Apple have made the greatest contributions.

In the end, it was concluded that IBM was the world's best.

So far, most of the world's commercial mainframe computers have been provided by IBM.

As a world-class technology giant, IBM has a large branch in the capital of China, which is responsible for most of its business in China.

If Lin Han wants to buy a mainframe, his first choice is naturally to go to IBM Huaxia Capital Branch.

Of course, before that, he had to find a reliable hardware engineer to help him handle the purchase and placement of the mainframe.

Lin Han had a choice in his heart for this, but it was an old colleague of him when he worked in the capital, a super honest man who is almost forty years old this year but is still single.

……

Su Xiangyuan was wearing a pair of thick black-framed glasses, a plaid shirt and big pants, and he was a little sloppy, he was sitting in front of the computer, and he was typing on the keyboard with some excitement at this time.

"Dear Xin, we're going to meet tomorrow......"

It turned out that this was a female netizen he met on a blind date website, and the two had a good conversation, and within a few days, they chatted hotly and proposed to meet.

As the most senior and skilled hardware engineer in the company, Su Xiangyuan can be said to be worth a lot of money, but due to various reasons, he has not been able to get rid of the single state.

It is only in the past few days that the dawn of hope has gradually revealed.

Female netizens sent a message "Uh-huh".

This "uh-huh" made Su Xiang's heart bloom and he was extremely excited.

The female netizen came again, "What do we have to eat when we meet?"

Su Xiangyuan pondered for a second, his eyes lit up, and then he typed, "Let's go eat hot pot." ”

After the message was sent, there was a long silence on the other side.

He was stunned for a moment, and then he hit another of his favorite dishes.

"Do you want to be spicy?"

The female netizen was silent again.

At this moment, Su Xiangyuan's mobile phone suddenly rang, but the caller ID was "Lin Han".

After connecting the phone, I only heard Lin Han say with a smile: "Old Su, how are you doing lately?"

Su Xiang laughed: "It's still the same, a single dog for many years, but I heard that you have been mixing well recently, and you have been talking and laughing with Ma Ling." ”

At this time, a female netizen sent a message "Let's eat hot pot", but his attention was completely gone......
