After sending Gu Tao and Bao Jiaqi away, the project team went to the courtyard of Gu Song's house, had a good meal, and then started the holiday.

When the holiday is over, it is to connect with the meteorological department.

First of all, the daily forecast data is compared, and the calculation speed, budget ability, and accuracy will be seen by the veterans.

So, when the big cold wave before the Spring Festival is predicted earlier, it should attract a little more attention, right?

In the past six months, others have looked at the results of the Flint Research Institute and feel that the speed is fast, but Gu Song is actually quite relaxed.

08 is a critical year.

For this reason, the underground laboratory of the Xiangshan Annex, there is almost no stop.

After two days of being tired of Xie Yinran, she entered the final exam state again.

Gu Song, on the other hand, concentrated on preparing for the first launch on Flint Island.

As an enterprise, there is absolutely no need for his launch site to wait until it is built to meet the specifications before it is put into service.

What's more, this launch has a special mission.

Therefore, after more than half a year of intensive construction on the flint island and the rough construction of the launch site, the first customized candle dragon rocket provided by the Aerospace Science and Technology Group, as well as the non-critical parts of the "test satellite" that Gu Song tinkered with in the Xiangshan Courtyard, arrived on the island by sea.

Then, at a high cost, the team that came to Flint Island to help with the rocket hoisting and testing was carried out.

In order to show his attention, Ye Ziheng also went to the island.

Looking at the space launch site, which was still rough, he said helplessly: "Why do you have to come here to launch? There are many variables in ocean shipping, and now the foundation here is poor. ”

Jian Yushu disagreed: "I always have to enter the next stage." The team trains with you every day, and you also need to go through some practical projects to gain experience. ”

Ye Ziheng shook his head: "You are really willing to spend money." ”

Of course, the normal thing is to learn, boil, and accumulate experience year by year. For such a long period of time, the remuneration package of these people is very average.

It's another form of cost reduction, exchanging time.

And Flint Aerospace is the opposite, preferring to exchange money for time and let the team grow rapidly.

He looked at the busy crowd in the hoisting workshop and the candle dragon rocket, and prayed that it would successfully complete its mission by then.

Although he was worried in his heart, the level of the team was really not as good as other launch sites, and even if there were problems, it was understandable.

But after all, this is the first candle dragon rocket delivered by the Aerospace Science and Technology Group, if this is the case, it will fail directly, how much does it hurt?

Coming out and looking at the seamless steel rails on the ground, Ye Ziheng became more and more emotional: "You are engaged in aerospace, that is really serious!"

Jian Yushu smiled a little arrogantly, of course.

When it comes to goals, now Flint Aerospace is beating the world.

Not long ago in November, SpaceX successfully launched another test and made a loud noise, saying that the next step was to deliver cargo to the International Space Station and break through docking technology.

Jian Yushu couldn't wait for time to speed up, and hurried to the next stage.

Helplessly, this is the reality of the situation.

Flint Aerospace is already too showy to make the whole world nervous.

He looked at the launch team that was busy preparing and thought about the mission of this launch mission, and sighed secretly in his heart.

……

Yan Jing, in the project team of quantum computers, there is an expert from the meteorological department, Kou Xun.

He's been in shock these days.

He never imagined that he would see a quantum computer in his lifetime.

It's not the kind that the media brings, it's the kind that has physical objects and plays a role in areas that he can understand.

Under the instructions of the big leader, the meteorological data saved over the years were brought over.

Open access to available global meteorological data has also been collected as much as possible.

Then, while the weather forecasting and prediction algorithms now used by the meteorological department were compiled into the computing programs of quantum computers, a group of people used artificial intelligence to iterate and prepare optimization algorithms with the help of Zhang Qingping.

The first wave that hit Kou Xun was actually the most intuitive, that is, the speed of calculation.

Weather forecasting is a numerical weather prediction at the level of calculation.

To put it simply, after years of research, scientists have come up with six systems of atmospheric equations of motion. The temporal and spatial variations of the wind, pressure, density, and temperature fields in the atmosphere can all be described by this set of equations.

In fact, these systems of equations are all cases under idealized conditions.

Just as vacuum and non-vacuum, smooth and frictional, these equations need to be parameterized to really calculate and parse them.

In addition to meteorological observation data, which are the initial conditions for analysis, there should also be analytical scales.

This scale is a little bit similar to resolution.

The atmospheric environment is figured out, and all changes are related. If you want to calculate, let's draw the grid first.

First of all, from the surface to the top layer of the atmosphere, it is divided into n layers.

Then, on the surface, also divided, a lattice is x km long and wide.

In this way, you get, well, the surface area of 510 million square kilometers divided by the square of x, probably millions of squares. Millions multiplied by n, OK, that's tens of millions of lattice points that need to be calculated.

Then, it depends on whether you calculate the change in the value in each cell for 10 minutes, 30 minutes, or longer.

If it's a 10-minute calculation, you have to make a 10-day forecast. Well, then each grid will be counted 1440 times.

For a real-world example, with a resolution of 15 kilometers per grid, it would take two hours a day to complete a system of equations of atmospheric motion in a column of 40 billion grids. Then, the changes in the values provided are used as the basis for the weather forecast by professionals.

Partial differential equation + floating-point number calculation + horizontal n lattice points + vertical n layers + time step limit + parameterization scheme + ...... Supercomputing is tiring......

The calculation also takes into account the issue of timeliness, and the result just came out today but the sun has gone down, and the daylilies are cold, who looks?

Weather forecasting is such a tangled process. Predictability is rooted in the interaction of atmosphere, land surface, vegetation, sea ice and sea surface. And there are always unpredictable factors on a small scale, which are related to the "chaos" theory.

At present, the limit of 12 kilometers of resolution is already very painful, and it is even ridiculed that the calculated speed cannot keep up with the speed of the actual change of the atmosphere.

For example, at a resolution of 1 km, changes caused by special factors such as small clouds cannot be included in the calculation.

The reason why Kou Xun was so shocked was that it took the quantum computer to complete an equal number of calculations.

17 seconds.

In the data brought over, the results of many supercomputing calculations in the past are saved for comparison.

Kou Xun stayed there like a chicken, while Zhang Qingping and Guo Yue were muttering and discussing.

"What's the problem, how can it take so long?"

"Does the error correction mechanism have to be optimized specifically for this model?"

"Lao Zhang, take a look, are there still some problems that can be transformed in a way that is more suitable for quantum computing?"

"I think that if we think another way of thinking, will we increase the resolution and use more data to map to each other, but will improve the fidelity rate?"

"Anyway, there must be something wrong with the timing. 100 qubits! If the supercomputing time is about 2 hours, what can happen here that it can reach less than 10 seconds, right?"

"Let's take a walk, analyze the data, and quickly change it and calculate it. ”

Kou Xun, who was holding the result, looked dazed.

17 seconds, why are you so upset?

Who am I, where am I, and what happened?
