However, this project was only carried out for more than half a year before it was thoroughly criticized by industry insiders.

After Taiji Co., Ltd. undertook this project, the amount of equipment purchased alone exceeded 200 million yuan. Including other expenses, the actual investment in the website has exceeded 500 million yuan.

All the money is paid for by the Ministry of Railways.

"Twenty-first Century Economic News" disclosed this, saying that the various institutions involved in the project bidding have "extremely close relationships", which also involve related transactions, self-circulation procurement and other behaviors.

The report also stated: “The Information Technology Center of the Ministry of Railways purchased its own products through the intermediary Taiji Co., Ltd.” and “the price of the products doubled several times after several changes of hands.”

Everyone knows the secrets of this.

I won’t go into details.

Immediately after the incident broke out, some people suspected that the Ministry of Railways was "keeping the money from outsiders" and only outsourced a small range of business to other companies, leaving most of the business to "its own people."

The often-cited evidence is that the Ministry of Railways rejected the mature solution provided by IBM and the distributed solution from Tsinghua University's Web and Software Technology Research Center long before the tendering process for the passenger ticketing system.

"IBM's mature solution" was rejected because the price was too high.

According to relevant sources, IBM's offer is 190 million.

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

Amid the skepticism, although Taiji Co., Ltd. completed the construction of the 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.

Almost all netizens who have used it are scolding it.

Since we had no simulations and no experience in handling huge traffic, after the Spring Festival travel online ticket purchase was launched, the website could not even be logged in for a time.

This has once again pushed the website to the forefront.

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

In the end, the Ministry of Railways could not withstand the pressure from the outside world and had no choice but to bite the bullet. In the name of technical exchange, the Academy of Railway Science sent relevant personnel to go south to contact Infinity Company.

At exactly this time, Infinity Company, 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 transmission technology used now is very mature and can be used directly.

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

The key to limiting the emergence of photonic computers still 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 is speed. Without high-speed memory for data conversion, the advantages of photonic computers cannot be realized at all.

But how is light stored?

Almost all researchers in the Optoelectronics Laboratory are devoted to the research of this project.

As long as the storage of optical information is solved, the rest is a matter of modern integrated circuit technology. As long as the phototransistors are continuously miniaturized, new computers that surpass current computers will soon be made!

It has been five or six years since the establishment of the photonic computer project team, and the funds consumed have reached a terrifying amount of more than 200 billion, and there are countless other additional resources.

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

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

But with the strong support of Chen Weidong, and after several years of continuous investment, photonic computers finally ushered in a glimmer of hope!

The project team successfully developed the world's first pure photonic chip in the laboratory.

It is a three centimeter by three centimeter square chip with a bright silver metal cover, which seems to be not much different from other chips.

But if you look closely, you will find that there are countless densely packed holes on the front, back, and sides of the chip.

These holes are so small that it's easy to mistake them for dust on the chip.

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

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

Due to the difficulty of processing, a total of 1.3 million phototransistors are integrated into this chip. In terms of this level of integration, it is only 50,000 more transistors than Intel's Pentium 4.

The only difference is that the Pentium 4 uses electron tubes, while this optical chip integrates phototransistors.

The densely packed small holes on the surface of the chip are the laser converters used for optical transmission. There are more than 16,000 optical converters like this. On average, every eighty phototransistors can share one optical transmitter.

In addition, this chip fully utilizes the characteristics of light and adopts an unprecedented quinary calculation method.

Red, orange, yellow, green, blue, purple, these seven colors of light, the project team used the five most easily identifiable colors of red, orange, yellow, green, and blue, which represent different data information, to develop this quinary system.

processor.

The quinary system is a very niche base system. Although it has many shortcomings, it is just right when used on photon processors, which can bring out the characteristics of photon computers to the extreme.

The theoretical maximum speed of a photonic computer is one quadrillion times.

The first-generation photonic processor using the quinary system, although its transistor integration level is similar to that of the Pentium IV, is seven to eight hundred times faster than the Pentium IV!

Compared with the photoelectric hybrid processor currently used by Infinite Company, the pure photonic chip has only just come out and has shown extraordinary power.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! The current low integration level provides unlimited imagination for the subsequent development of photonic chips.

Researchers at Infinite Company couldn't put it down.

Its power lies not only in the improvement of computing speed, but also in its 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 photon processors are born to be used as special chips for ultra-large and complex data processing!

A supercomputer built with this kind of processor only requires three or four blocks, and can reach or even exceed the processing speed of the latest supercomputers of Infinity Company.

It can easily perform calculations exceeding a petaflop, billions of billions, and tens of billions of times with ease!

Faced with the request for help from the Academy of Railway Sciences, Infinite Company sent more than a dozen technicians to form a project team and came to the ticketing system monitoring center of the Academy of Railway Sciences to replace them with a supercomputer built with a photon computer.

After that, optimization plans such as adjustment of the internal and external network security platform, optimization of queuing machine encryption strategies, optimization of database applications, dynamic control of user login, optimization of payment process, and page compression and transmission were implemented.

It only took four days to get the website running smoothly!

During the peak of the Spring Festival travel season, under the impact of huge data, users who logged in to the website to buy tickets did not feel any lag at all, and the entire data exchange and calculation process was extremely smooth.

Even some veteran experts from the Computer Research Institute expressed their disbelief and were dumbfounded.

Thanks to the book friend "Xiuchang" for the 500 starting coins!
Chapter completed!
