The ups and downs of life in the Siheyuan

Back in the laboratory, the body design responsible for Nuwa 1 has also been completed.

The appearance is very similar to that of a manta ray, with transceivers placed at the two eyes.

The whole body is covered with flexible materials, the internal main frame is made of hollow high-strength carbon fiber, and part of the structure is made of titanium alloy.

The wingspan is 1.2 meters, which is equivalent to that of an ordinary adult manta ray.

The back is available in black or gray-blue colors, the belly is gray-white with scattered dark spots, and the body is like a huge blanket.

In addition, there is a round and thin tail on the back of its body, like a "sea kite".

It can imitate a manta ray, flap its two large pectoral fins, and swim in the deep sea.

In theory, it can complete common actions such as turning, 360-degree rolls, and maneuvers.

The design weighs less than 32 pounds and is equipped with the latest lithium-ion battery with a battery life of up to 3 hours.

It is also equipped with an eddy current surge generator on its back. When the battery is out of power, it can lie on the seabed and release a wave energy collection device to convert the vortex surge of water into electrical energy.

Therefore, in theory, manta rays can last indefinitely.

Li Yuan copied the design drawings, underwater acoustic transceiver, and body material requirements to a USB flash drive.

After handing these design materials to Guo Kai, Li Yuan could finally relax for a few days.

There was no way. Ever since they learned about the project Li Yuan was going to work on, although the military had provided the greatest convenience, it had put great pressure on Li Yuan by following the progress every day.

During the entire process of the experiment, a senior colonel named Li Jun in his early 40s provided services throughout the process.

Whether it's accommodation or food, the other party always provides the best.

The enthusiastic attitude put Li Yuan under great pressure.

While he was not busy, Li Yuan began to build a copy of Nuwa 1.

The current Nuwa 1 is limited by its battery capacity and cannot increase its computing power. Otherwise, frequent charging will cause a person to collapse.

However, future work will require more and more computing power, and he can no longer do without her assistance.

Therefore, I thought about designing a copy for her with higher computing power and larger data storage.

In order to achieve the target computing power, Li Yuan designed a large computer matrix composed of 64 nodes.

All nodes are connected to the server through network cables, and the server is connected to the hard disk array.

The core of each node is 4 Zu Chong 200 CPUs, each CPU comes with 1G of memory.

The server is responsible for distributing tasks to all nodes and collecting results, and all nodes perform operations in parallel.

Through Starlight or Super Interface, Nuwa 1 can distribute some computing tasks to her replicas.

If high-computing power work can be completed by replicas, she mainly considers top-level design and system framework design.

In this way, the copy has already acquired intelligent computing capabilities.

Through repeated trade-offs, a parallel programming model based on message passing was added to the Galaxy operating system, allowing different nodes to share disk arrays.

After he completed the system design with the assistance of Nuwa 1, he thought carefully and realized that the entire copy was what later generations would often call a supercomputer.

Taking into account the need for domestic technological breakthroughs, Li Yuan decided to make it public after thinking for a long time.

Supercomputers can serve many fields such as military, medicine, meteorology, finance, energy, environment and manufacturing.

It is an important basic tool for scientific research breakthroughs in our country.

But too much advanced technology is used in it, and confidentiality has become its first choice.

Li Yuan ordered Nuwa No. 1 to write a project plan, and he started calling Leader Xu and Mr. Chu.

The next morning, four people huddled in front of a CRT monitor.

"This is my latest designed CPU. It's called Zuchong 200. Its performance is as follows..."

"This is my definition of a supercomputer. It can help many industries improve work efficiency and can be used in the military..."

“The computing power is 10 billion times per second, the system can be expanded to 1024 nodes, and the computing power can be increased to 160 billion times per second.

Of course, this is only theoretical data, and the actual computing power needs to be verified in real objects."

"Each node is composed of 4 latest Zu Chong 200..."

"Its appearance will rewrite history!".

During Li Yuan's explanation, Leader Xu, Mr. Chu and Mr. Tong continued to express admiration.

Leader Xu is in charge of the Science and Technology Department, and Mr. Chu is in charge of new weapon verification.

It can be said that I am familiar with computers.

Such a huge increase in computing power left them all dumbfounded and unbelievable.

"Xiao Li, are you trying to trick us?"

Although Leader Xu knows Li Yuan, he still can't believe such a huge improvement until now.

"You know my character. I will not mess around in this matter. I have checked all the data repeatedly."

"Lao Li, you are launching satellites, how do you let others live!"

Representative Tong wanted to hug Li Yuan's neck, but he easily dodged it.

"Today I finally know why those Americans have been trying to trick you into going to them. You are so terrible."

Mr. Chu accidentally pulled off a beard and started hissing.

"As far as I know, America and Xiaori are both working on supercomputers, and I remember their computing power is in the millions.

This computing power makes people who are engaged in mathematics, H laboratory, etc. envious."

Leader Xu was deeply affected by this. Since taking office, some domestic institutions have requested the introduction of advanced foreign supercomputers.

Some universities and research institutes have frequently requested to increase their budgets and develop their own supercomputers.

Just this year, our country developed the STAR-100 (Galaxy-) supercomputer, which has a computing power of million times per second.

It is improved on the basis of the America Cray-1 machine.

Cray-1是1975-76年艾美莉卡推出一种的64位机，运行频率80MHz/160~240MIPS，拥有向量指令集和浮点指令集，具备12条独立的流水线执行单元，每个时钟周期最大可执行3条浮点指令。

Its memory bus width is 24 bits and its memory capacity is 8MB. The full system power rating is up to 115 kW.

Its CPU is not built using large-scale integrated circuits, but smaller-scale integrated circuits, with a total of 512 PCB boards.

The total area of ​​PCB boards reaches 32 square meters, and the length of signal lines connecting these PCB boards is up to 80 kilometers.

In order to ensure signal synchronization, the length of each signal line is carefully calculated.

It uses only four integrated circuits, two different speeds of 5+4 NOR gates, 1Kbit SRAM, and 16x4-bit registers.

Each PCB is covered with these densely packed chips, which are then connected together with wires.

This is only slightly better than the past transistor computers, which are essentially composed of discrete micro-scale integrated circuits.

These four types of micro-scale integrated circuits can all be produced domestically, so the reliability of Galaxy One can be imagined.

The Galaxy 2 developed later used Intel's CPU.

America introduced many restrictions on the Cray-1 that year.

1. Performance must drop significantly (from 1 million times per second to 400 million times per second);

2. It can only be used for geological exploration and cannot be used in other fields;

3. The key to the computer room is held by the Americans. Every time it is used, it must be reported to them for approval. It can only be used after approval, and there must be supervision by the Americans when using it.
