Revisiting Future Path

No. 084 Only the device and the name, can not be fake

However, the Spring and Autumn series companies are small companies after all.

Wei Dongsheng recklessly sacrificed a big killer that disintegrated the existing firewall principle, and he would definitely usher in uncontrollable peeping. Therefore, Wei Dongsheng screened the preciousness of the information and deliberately kept the core technologies that IBM and other companies had guarded against. Only relatively less core information would be shared with Xiao Lei.

To be honest, the information is incomplete, but Xiao Lei feels it is normal: If companies such as IBM are so slack that their core information is stolen casually, how can they be worthy of their reputation.

Moreover, Xiao Lei did not care about network security.

These days, Xiao Lei has poured all his energy into the supercomputer design scheme of Wei Dong's life called "Cambrian 2004".

Xiao Lei was very ashamed. After more than ten years of experience, he could not understand Wei Dongsheng's "Cambrian 2004" supercomputer architecture. At first, Xiao Lei laughed that this was a fantasy design plan, and studied the error correction mentality, trying to find enough reasons to reject this design. However, Xiao Lei became more and more horrified when error correction came and went. The daydream-like heterogeneous algorithm and architecture of "Cambrian 2004" could be logically self-consistent.

The design scheme of the "Cambrian 2004" supercomputer was not complete and error-free. Xiao Lei's horror was that there were no obvious errors in the theory.

In other words, the design plan Wei Dongsheng gave him is very likely to be true.

if it is real……

The supercomputer circles in China and even the whole world will cause violent shocks.

Xiao Lei did not believe that "Cambrian 2004" was designed by Wei Dongsheng, and asked about its origins euphemistically: "Which company is the upcoming product of Cambrian 2004?"

Wei Dongsheng: "Wisdom Universe Information Industry."

Xiao Lei couldn't laugh or cry and said: "The Cambrian 2004 is indeed very detailed. However, there are still many key issues that need to be resolved if I want to turn it from a theoretical hypothesis into a real product. Although I have worked at Suguang for more than ten years In 1991, I witnessed the development process of "Dawning 1000" to "Dawning 4000-L", but never practiced a supercomputer project based on heterogeneous computing. Even the "Dawning 4000A" in preparation, the chip only uses AMD_Opteron_850 Processor. In front of the'Cambrian 2004', I was a primary school student who needed to make up lessons. I had to communicate with the designer further to quickly turn the theory into reality."

Wei Dongsheng understood Xiao Lei's attitude.

Wei Dongsheng examines the history of supercomputer development and is simply divided into several stages: the traditional era, the computer era, the energy-saving era, and the heterogeneous era.

In the early days, every supercomputer was very expensive, because not only the processor needed to be specially designed, but also the high-speed internet connection cables were also specially customized. In the era when supercomputers were beyond reach, Wei Dong's life was called the traditional era. Every supercomputer at that time was a real supercomputer.

With the rapid development of personal computers and networks, people began to try mass-produced computer accessories, such as supercomputers. Several personal computer-level chips are connected through the network, and then processed in parallel after splitting tasks. The performance is not weaker than those of expensive special-purpose computers, so supercomputers began to become civilians. Wei Dongsheng named this era the Zanji era.

Zanji has its limits. For example, suppose that a person spends 6000 seconds to dig a well. With simple digital substitution, 6,000 people cannot dig a well in one second. 6000 people are more efficient than one person, but they cannot dig a well in one second. This is the limitation of parallel computing and the shortcomings of Zhanji supercomputers. After research, one of the core issues that limit the number of machines is power consumption. Power and heat issues make it impossible for people to pile up CPUs to make supercomputers indefinitely. As a result, supercomputer developers no longer pursue the high performance of a single core, and instead consider issues such as power consumption and power saving. IBM announced the successful development of the Blue_Gene supercomputer this year, which is the work of this concept. Wei Dongsheng named this era the energy-saving era.

At the end of 2003, IBM's blue gene had just started the climax of the energy-saving era.

The "Cambrian 2004" presented by Wei Dongsheng is a heterogeneous era after the energy-saving era.

The so-called heterogeneous, the simplest and most straightforward impression is that the CPU is paired with the GPU. Before the heterogeneous era, for example, the "Dawning 4000A" supercomputer in preparation, all basic chips are CPUs; the supercomputer in the heterogeneous era, such as the famous "Tianhe No. 1" supercomputer in the future, has a collection of 6,144 CPUs and 5120. GPU. CPU paired with GPU is an image concept, and the technical reserve behind it is heterogeneous computing.

At the end of 2003, heterogeneous computing has not yet received strategic attention.

Speaking of, the beginning of the heterogeneous wave should be traced back to the Cell processor.

As early as 2001, Sony announced that it had hired IBM to design the processor "Cell" of the PS3 game console, saying that the Cell's computing power would reach an unprecedented one trillion floating point calculations per second. At that time, the first reaction from the outside world was that Sony and IBM were bragging. From 2001 to 2003, Cell has not yet completed its design, and public opinion has gradually forgotten the Cell project.

Wei Dongsheng knows that the Cell project will be successful in the future, and heterogeneous computing is also feasible

Heterogeneous computing is the general trend of the future.

Therefore, Wei Dongsheng played a half-step forward and came up with a supercomputer design scheme with a heterogeneous computing structure.

If all goes well, "Cambrian 2004" will set off the first wave of heterogeneous computing.

If Wei Dongsheng only used his mouth to say that CPU and GPU can work together, Xiao Lei laughed with great probability. Similar ideas, in fact, have long been exaggerated propaganda by public opinion, saying that it is possible to develop personal supercomputers with GPU features; that is, the concept of heterogeneous computing, which also appeared as early as the mid-1980s. However, the gap between the concept and the theory, and the theory and the reality, is more than vast. Wei Dongsheng’s greatness lies not in proposing the concept of heterogeneous computing supercomputers, but in proposing detailed theories that can be implemented by virtue of his solid plagiarism or reference basis.

If Wei Dongsheng's design is full of loopholes, no matter how forward-looking it is, it will be difficult for Xiao Lei to really take it seriously.

The development of supercomputers is a highly professional job. Who has the leisure to listen to the daydreams of a high school student? In this era when the wave of heterogeneous computing has not yet fluctuated, not everyone is spending money and energy to improve the heterogeneous computing framework. Wei Dongsheng's design plan is complete and complete and no key errors can be found. He pointed out a direction that Xiao Lei will shock the "Cambrian 2004" such an unprecedented heterogeneous computing structure supercomputer.

Wei Dongsheng frankly faced Xiao Lei’s doubts and smiled and said, “I have already said that I am the designer of the Cambrian 2004. If you don’t believe me, if you have any questions, just ask me.”

Hearing such confident sonorous words from Wei Dongsheng, Xiao Lei was taken aback: "You really designed it?"

Wei Dongsheng: "Come and test me."

Xiao Lei hesitated for a few seconds, confronted Wei Dongsheng with a straightforward personality, and pointed to a solution: "Why is this design here?"

Wei Dongsheng is very familiar with the framework of the "Cambrian 2004" supercomputer, and immediately gave a long detailed explanation: "Here, I have calculated the task mapping and scheduling mechanism. Such an algorithm is more efficient and can optimize resource allocation... "

Wei Dongsheng talked freely and introduced Xiao Lei to the optimization concept of resource allocation.

Experts know if there is any when they speak.

Xiao Lei communicated with Wei Dongsheng on technical issues for a while, and immediately understood that Wei Dongsheng did not know how to pretend, but really understood.

I really understand!

If you really understand, then the so-called simple...?

Does Wei Dongsheng find it simple?

!

Xiao Lei couldn't help taking a cold breath.

What a talent this is.

Xiao Lei previously looked down on Xiao Lei because he was a sophomore in high school, and now he looks up on Wei Dongsheng because Wei Dongsheng is pretending to be boastful, misunderstanding that Wei Dongsheng is a true genius.

Xiao Lei is actually more receptive to the aura of genius than ordinary people, because his alma mater Tsinghua University and neighboring Yanjing University are both the highest universities in China. The college entrance examination champions and peers are pushed into it every year, and there is never a lack of rare animal type geniuses. Soil. In other words, before Xiao Lei was admitted to Tsinghua University, the computer in his mind was a super radio. At the beginning of enrollment, Xiao Lei didn't understand computers and didn't like computers very much. Xiao Lei has a classmate who can calculate calculus mentally and calculate Fourier transform verbally, which makes people doubt his brain structure. The reason why Xiao Lei later became enthusiastic about studying supercomputers was entirely because he was stimulated by this classmate's powerful mathematical talent and felt that he had to be equipped with a supercomputer to catch up with him.

Xiao Lei misunderstood that Wei Dongsheng was a super genius like his classmates.

Thinking of old classmates saying that calculus is not harder than addition and subtraction, thinking of Wei Dongsheng's saying that supercomputers are simple, Xiao Lei seemed to see the ladder between evildoers and humans.

Xiao Lei has seen many geniuses, and is also used to these talented and enchanting geniuses. Xiao Lei simply accepted the "fact" that Wei Dongsheng was an extraordinary genius, and when he knew his mistake, he changed his style and apologized to Wei Dongsheng: "You really designed "Cambrian 2004". Hey, standing with you geniuses, I always feel like I am A chimpanzee that has not yet fully evolved."

Wei Dongsheng smiled: "Itching for a while."

More than ten years after Xiao Lei graduated, his thinking has gradually matured, and he no longer wastes time inferiority or feeling other people's talents, and prioritizes his own work. It was verified that Wei Dongsheng really understands supercomputer design, and that the supercomputer of the heterogeneous computing framework is really operability, Xiao Lei enthusiastically discussed with Wei Dongsheng.

At the same time, Wei Dongsheng had no intention of letting go of supercomputer affairs.

Wei Dongsheng’s weapon for galloping the Internet is computer intelligent life, and supercomputers are the basis for the advancement of computer intelligent life cyanobacteria to Blue Fern. To control one hundred percent of computer intelligent life, one must control one hundred percent of supercomputers. If he does not understand the basic knowledge and infrastructure of supercomputers, how can Wei Dongsheng dare to use computer intelligent life at ease?

Computer intelligent life is not a pet bound in the game. If unfortunately encounter a special situation, it is not impossible for a hostile force to steal the supercomputer and persuade the computer's intelligent life to be reduced. In order to avoid such accidents, Wei Dongsheng must master the core technology of supercomputers and control the intelligent life of computers in a true sense.

Some interests, such as cooperation with Huo Yongshan, such as the use of the power to make people stronger; and some interests, such as computer intelligent life, Wei Dongsheng must be held firmly in his hands.

Zuo Chuanyou said: Only implements and names should not be fakes.

That's the truth.
