God-level Trader of Rebirth

Chapter 379 The Dawn of a New Era

However, this project has only been carried out for more than half a year, and it was picked up by people in the industry.

After Taiji Co., Ltd. undertook this project, the purchase amount of the equipment alone exceeded 12306 million yuan. Including other expenses, the actual investment of the 5 website has exceeded [-] million yuan.

And all the money is paid by the Ministry of Railways.

"21st Century Business News" disclosed this, saying that there is an "extremely close relationship" between the agencies involved in the bidding of the 12306 project, which also involves related transactions, self-circulation procurement and other behaviors.

The content of the report also stated: "The Information Technology Center of the Ministry of Railways, through the intermediary of Taiji Stock, purchased its own products" and "the price of the products has doubled several times after several times of handover."

Anyone who knows the way of doing this understands it.

I won't go into details.

Immediately after the incident fermented, some people suspected that the Ministry of Railways was outsourcing only a small range of business to other companies, and most of the business was handed over to its "insiders".

The evidence that is often cited is that the Ministry of Railways rejected the mature solution provided by IBM and the distributed solution provided by the Web and Software Technology Research Center of Tsinghua University long before the bidding for the passenger ticket system.

"IBM Mature Solution" was rejected on the grounds that the asking price was too high.

According to relevant sources, IBM's offer is 1.9 million.

The distributed solution provided by Tsinghua University was also rejected on the grounds of immature technology.

Amidst the doubts, although Taiji Co., Ltd. completed the construction of the 12306 project, after the official operation of the website, it was on the verge of paralysis many times, and various problems, large and small, emerged one after another.

There are countless posts of complaints and abuse on the Internet.

Since there was no simulation and no experience in dealing with huge traffic, after the launch of the Spring Festival travel online ticket purchase, the website could not be logged in for a while, and it was under maintenance almost every day.

This made the 12306 website once again pushed to the forefront.

Among the many complaints, some netizens called for Infinity to lend the elites of the computer department to 12306 for a few days, or to hand over the railway ticket system to Infinity.

In the end, the Ministry of Railways couldn't withstand the pressure from the outside world, so it could only bite the bullet, and in the name of technical exchanges, the Academy of Railway Sciences sent relevant personnel to the south to contact Infinity Company.

Just at this time, Infinity Corporation, the photonic computer project team of the Optoelectronics Laboratory, made significant progress.

The core part of a photonic computer lies in light transmission, light computing, light control, and light storage.

Light transmission is a problem that has been solved a long time ago. The optical fiber technology transmission technology used now is very mature and can be used directly.

At the same time, "light computing" can also be realized.

The key to limiting the emergence of photonic computers lies in optical storage and optical control.

Optical storage does not refer to storage media such as optical discs and VCDs, but optical memory.

The biggest advantage of photonic computers lies in speed. If there is no high-speed memory for data conversion, the advantages of photonic computers cannot be reflected at all.

But how is light stored?

Almost all the researchers in the optoelectronic laboratory have devoted themselves to the research of this project.

As long as the storage of optical information is solved, the rest is the matter of modern integrated circuit technology. It only needs to continuously miniaturize the phototransistor, and soon a new type of computer that surpasses the current computer can be made!

Five or six years have passed since the establishment of the photonic computer project team, and the cost of funds has reached a terrifying 2000 billion, and other additional resources are countless.

It can be said that at this stage of the project, every researcher is under tremendous psychological pressure.

If it was an ordinary company, it would have been dragged down by such a costly project long ago.

But with the strong support of Chen Weidong, after several years of continuous investment, photon computer finally ushered in its ray of dawn!
The project team successfully developed the world's first pure photonic chip in the laboratory.

It is a three centimeters by three centimeters, square chip, showing a layer of bright silver metal cover, it seems that it is not much different from other chips.

But as long as you observe carefully, you will find that the front and back of this chip, as well as the side, have countless densely packed small holes.

These tiny holes are so small that they could easily be mistaken for dust on the chip.

Another special thing is that the whole chip has no pins for mounting on the circuit board and exchanging data.

The all-metal case is a flat piece, like a capacitor.

Due to the difficulty of processing, a total of 130 million phototransistors are integrated in this chip. In terms of this integration level, it is only [-] transistors more than Intel's Pentium [-].

The only difference is that Pentium [-] uses electron tubes, while this optical chip integrates phototransistors.

The densely packed small holes on the surface of the chip are due to the laser converters for optical transmission. There are more than 6000 such optical converters. On average, every [-] phototransistors can share one optical transmission device.

In addition, this chip gives full play to the characteristics of light and adopts an unprecedented quinary calculation method.

Red, orange, yellow, green, blue, blue and purple, these seven colors of light, the project team adopted the most easily recognizable five colors of red, orange, yellow, green, and blue, which represent different data information, and thus developed this five-ary system processor.

The quinary system is a very small number system. Although it has many shortcomings, it is just right when used in photonic processors, and it can bring the characteristics of photonic computers to the extreme.

The theoretical maximum speed of a photonic computer is 1000 trillion times.

And the first-generation photon processor using the quinary system, although the transistor integration level is similar to that of the Pentium [-], its speed is seven to eight hundred times faster than the Pentium [-]!
Compared with the optoelectronic hybrid processor currently used by Infinity, the pure photonic chip has shown extraordinary power just after it came out.

The current low level of integration provides unlimited imagination for the subsequent development of photonic chips.

The researchers of the Infinity Company couldn't put it down.

Its power is not simply an increase in computing speed, but a greater advantage lies in parallel processing capabilities.

The application of five-color light sources allows the photonic chip to process data from five ports at the same time, which is five times the parallel processing capability of ordinary electronic chips. Its significance is very far-reaching!
It can be said that photonic processors are born to be used as dedicated chips for super-large and complex data processing!

A supercomputer built with this kind of processor only needs three or four yuan, which can reach or even exceed the processing speed of the latest supercomputer of Infinity Corporation.

It is easy to perform calculations of more than [-] billion billion times, and it is also easy to perform one billion billion times and ten billion times!
Facing the request for help from the Academy of Railway Sciences, Infinity Company sent more than a dozen technicians to form a project team, came to the ticketing system monitoring center of the Academy of Railway Sciences, and replaced them with a supercomputer built by a photonic computer.

Afterwards, optimization schemes including internal and external network security platform adjustment, queuing machine encryption strategy optimization, database application optimization, user login dynamic control, payment process optimization, and page compression transmission were implemented.

It only took four days to make the 12306 website run again!

During the peak of the Spring Festival travel season, under the impact of huge data, users who log in to the website to buy tickets do not feel the slightest lag, and the entire data exchange and calculation process is also extremely smooth.

Even some old experts from the Computer Research Institute expressed disbelief and were stunned.

　Thanks to the book friend "Xiu Xiang" for the reward of 500 starting coins!
　　But I still want to say that a lazy dog ​​like me is very guilty and even feels unworthy.()
