Rebirth: I carry a desktop computer inside me

It's been a year since the last time the computer hardware in the body was replaced.

According to the current rhythm of Intel's annual release of a generation of CPUs, this year released I3/I5/I7 three generations.

Performance is a boost, but not particularly large.

The process was upgraded from 32nm to 22nm.

In the past year of use, the computer in the body has indeed improved a lot, and has played a great role in multi-threaded processing, fast charging chips, and RF chip design and development.

More importantly, through in-depth research, Jiang Cheng developed patches suitable for the operation of computers in the body and established a simulation laboratory.

However, the shortcomings are also revealed.

After all, it is just a personal workstation, and Shuanglu Zhiqiang really puts it on scientific research, but it is very general.

Even in the eyes of general supercomputing, this person's workstation is also a child's thing.

Jiang Cheng didn't want to go over and touch Xinghe No. 1, that thing was in Jinmen, not far from Kyoto.

But that is composed of 6144 general-purpose processors Intelzhiqiang E5540, and the photoelectric cost is scary enough.

Due to energy consumption, Jiang Cheng is still a little worried.

Don't calculate and drag down your body, then you can't scratch it.

So, forget about large-scale supercomputing, engage in a small supercomputing.

On the same day, Jiang Cheng instructed Guo Xiaoming to prepare a large room and order a small supercomputer.

The requirements are: each node is equipped with Zhiqiang X5675 (six cores and twelve threads), 2 Tesla K20X (2688 stream processors, 6GB of video memory), plus 32GB of DDR3 1600ECC memory.

2 compute nodes on each motherboard, 16 motherboards per frame, 4 frames form a cabinet, and currently only 2 cabinets are assembled, that is, 256 processors.

A high-speed interconnect router is shared between nodes.

It is expected that after the formation, Jiangcheng will have a 1536 processor cores and a computing speed of 50 trillion times per second.

Just for these hardware purchases, Jiang Chengcheng will spend more than 5 million yuan, and if you add the air cooling system, install and debug these, then the cost will reach 6 million yuan.

From a workstation of 20,000 yuan to a small supercomputer of 6 million yuan, Jiang Cheng felt that he was still good for the computer in his body, and at least tried his best to upgrade him.

Licking his lips, Jiang Cheng said that this hardware upgrade is really addictive!

No wonder there is an old saying, three thousand budget into the card, four way titans to carry home.

Just counting those frames makes men excited, not to mention that Jiang Cheng's small supercomputer has 6144 frames, and it takes ten minutes to count with his eyes!

Although it will take a while to carry it home (in the body), Jiang Cheng is already a little impatient.

After changing the supercalculation, it would not be cool to quietly touch a lithography machine with high precision.

As long as the simulation enters the laboratory, Jiang Cheng can first strip his clothes in the internal computer to study circuits and designs, and if he is very rich, he can also quickly enter the lithography machine industry.

As for now, sorry, the lithography machine is a game that can only be played by big guys, and his current little money is equivalent to looking for death and can't turn over a little wave.

Moreover, the lithography machine industry belongs to a special industry that is high-precision and has a large continuous investment, but the market scale is not particularly large.

At the beginning, in addition to Asmail, several companies such as Nissan studied lithography machines, but the final cost was too high.

Losing money all the time, they eventually gave up continuing their in-depth research.

Only Asmail, with the common support of the Western world, has grown up.

If Jiang Cheng really wants to engage in lithography machines, he will also be like Maple Microelectronics, which will be jointly invested by Hua Guo Company to support research, and then the results will be shared by everyone.

But this idea, at present, is not yet feasible.

Moreover, Jiang Cheng's research on lithography machines is very shallow, limited to reading related books and papers.

But the future is a viable direction.

In mid-September, a small supercomputer that cost a lot of money was finally formed under the installation of professionals.

As for the operating system, Jiang Cheng adopts a relatively mature Linux distributed operating system, which is only a simple optimization of the computing power scheduling of his own small supercomputing.

But time is tight, Jiang Cheng is not very proficient in the knowledge of operating systems, it can be used for the time being, but it is not the result of optimization.

Of course, power consumption is also a big household, and the peak computing power consumption per hour will reach more than 7800 kilowatt hours. (the data is wrong, the hour is not so high)

two cabinets, with a large number of network cables connected, cluster each computer together, through the high-speed transmission channel, distributed parallel computing.

After the boot and trial run, the screen on the side shows the Linux desktop, which contains task scheduling management software, as well as basic C compiler and other software.

After the company's personnel left, Jiang Cheng reached out and touched the cabinet.

In order to introduce these huge hardware of supercomputing, Jiang Cheng was fully prepared.

He first backed up the relevant design data, software and interface patches currently processed by the internal computer.

All kinds of BIOS and high-speed Internet systems for computer supercomputing are also prepared.

Through the interface program patch, Jiang Cheng no longer has to rely on the electric shock of physical current, but can actively touch it through biological current.

The original personal workstation was still turned off first.

That's when all the replacements begin.

Because it was very large, Jiang Cheng had to spend some time to let the supercomputer enter his body.

However, when he activated through his thoughts, Jiang Cheng's eyes suddenly turned black, and the person couldn't help but soften, but fortunately, his consciousness was still there, and he reached out to support the cabinet.

This feeling is like consuming a lot of energy at once.

Putting the chocolate in his mouth, Jiang Cheng replenished his energy.

The supercomputing in the body began to start, and he could feel the surge of electricity somewhere in the body, as well as the fragments of 1s and 0s.

The backup BIOS, Linux distributed operating system, these are not used.

Jiang Cheng estimated that it should be the function of the interface program patch, and the software-level data in the power-on was also simulated.

Because software, it is nothing more than stored through hardware and run by electric current.

With a full memory of 4096G, it took half an hour for the computer in the body to boot, which is still the result of the rapid operation of the computer in the body.

But under Jiang Cheng's dozen chocolates, it was finally turned on.

Jiang Cheng was meditating and saw the desktop of the distributed system.

The software inside is exactly the same as this supercomputer.

Opening the system management software, Jiang Cheng saw a large list of processor cores.

The overall occupancy rate is less than 1%.

Jiang Cheng quickly set up the computer in the body, and under normal standby conditions, he let more than 80% of the computing power be low-power standby.

After setting up, Jiang Cheng felt that his body's strength was recovering.

"It seems that until we find a way to solve the problem of energy supply, this supercomputer cannot really unlock and use."

Jiang Cheng shook his head with a wry smile, then the next step was added to his work.

That is to study the problem of computer energy supply and substitution in the body.
