By the time I arrived at the inpatient unit, it was past the patient's visiting time.

However, Su Xiaoxiao was obviously familiar with the medical staff here, and after whispering a few words with a nurse on duty in her thirties, Su Xiaoxiao was taken into the ward by another nurse, and Chen Xin was turned away.

Seeing Su Xiaoxiao's back disappear into the ward area, the nurse looked at Chen Xin and said with a smile: "You are Xiaoxiao's boyfriend, right? ”

Chen Xin nodded and asked, "Sister nurse, what kind of illness does Xiaoxiao's mother have? ”

The head nurse smiled at Chen Xin's sister's call, obviously having a very good impression of Chen Xin, she sighed in a low voice: "Xiaoxiao, this child, is too thoughtful, and likes to take everything to heart, no wonder she is reluctant to tell you about the situation at home." When she was younger, I was neighbors with their family, so I knew a few things about her family. To say that in the past, Xiaoxiao's family was still quite rich, her father made a lot of money in business in the nineties, bought a villa in Heyuan Villa in Jiangcheng City, and moved out of the community. She herself was raised as a baby by her family since she was a child, and she became more and more beautiful when she grew up, and later appeared in Chinese opera. ”

Everyone said that this child has a great future, plus the family has money, and no one will bully her when she enters the entertainment industry. Who knew that two years ago, less than half a year after she went to college, her father partnered with others to engage in private financing, but the other party took all the money away and ran abroad, Xiaoxiao and her father were arrested and sentenced to five years. The family's villa car was all auctioned by the court to pay off the debt, her mother was not in good health, she had been holding on for the past two years, and she didn't know what she was stimulated a few days ago, she cried and laughed at home, and hurt people, so she was sent here. ”

"Xiaoxiao was filming in Hengdian during this time, and basically came to see her mother every week. Her mother recognized her and didn't let anyone else get close, but she got sick again tonight, and it was too much trouble, so she had to call her. ”

Chen Xin was silent, and asked again: "Sister nurse, is Xiaoxiao's money in the hospital account enough?"

The head nurse said: "I looked at it two days ago, and there are more than 3,000, which should be able to be used until the end of this month." ”

Chen Xin thought about it and asked the head nurse to give him Xiaoxiao's account number, he took out his mobile phone and walked to the corner, pretending to be calling, and said in a low voice: ", give this account 50,000 yuan." ”

said: "From your private account or from the company's account?"

Chen Xindao: "Private account, how much money is still in it." ”

Gaga laughed: "There are more than 300,000 left, Lao Dou, in order for you to pick up the girl smoothly, I have lost all the money in, don't forget to pay me back when the time comes!"

Chen Xin said disdainfully: "Go aside!"

However, what he said is not wrong, although Chen Xin got a lot of money during this time, he couldn't use it, and the more than 70 million US dollars of the Swiss bank had not been moved, and Chen Xin took out the money to launder it when he was going to the Paris Air Show. As for "Bring Her Eyes", the box office will not arrive until at least next month.

So these days, Chen Xinquan relies on the support of's "Interstellar Survival Law", this novel has been praised by netizens as the first god book of Internet science fiction, with 50,000 words updated every day in the early days, and it can still guarantee 20,000 words updated every day, which is very sci-fi in itself.

Coupled with the endless black technology and the major civilizations that have appeared one after another, those sci-fi concepts that have never been heard of, reasonable plots, simple and accurate words, make book fans addicted, and the starting point has asked Chen Xin several times to publish this book, but Chen Xin has rejected it.

Even so, Chen Xin still received a huge monthly manuscript fee of 2 million, except for a part of the transfer to the company's account, the rest was given to Chen Xin for use.

About half an hour later, Su Xiaoxiao came out of it, and stopped talking: "Mr. Chen, I'm sorry for you today, I still have to accompany my mother at night, or ...... You go back first. ”

Chen Xin smiled: "Take good care of your mother, if you encounter any difficulties, then call me." ”

As he spoke, he turned to leave.

"Mr. Chen. ”

"Is there anything else?" Chen Xin said, turning his head.

Su Xiaoxiao showed a smile on her face and said, "Xiexie you!"

Chen Xin waved his hand, but his footsteps never stopped.

Su Xiaoxiao watched Chen Xin's back disappear behind the door blankly, and at this time, the head nurse came over and said, "Xiaoxiao, why did your boyfriend leave?"

Su Xiaoxiao shook her head and said, "He's not my boyfriend." ”

The head nurse said curiously: "It's not your boyfriend, then why did he transfer 50,000 yuan to your account?"

Su Xiaoxiao was slightly stunned and asked, "When did he turn around?"

The head nurse said, "Just now." ”

Su Xiaoxiao hurriedly ran to the middle of the corridor, leaned on the window and looked down, downstairs, a white Passat was slowly driving out of the hospital parking lot, she had a complicated look on her face, and muttered, "I will repay you." ”

After coming out of the hospital, Chen Xin directly dialed Yu Shijian's phone and recounted to him what happened at night, and made a special statement that he was very unhappy with the bag and the director.

Yu Shijian didn't expect Chen Xin to Yujian Su Xiaoxiao again, and he encountered that kind of thing, he hurriedly patted his chest and assured Chen Xin that he would definitely give him a satisfactory answer.

Chen Xin gave up.

……………………

That night, Chen Xin did not return to Hengdian, but returned to his home in Jiangcheng.

The next day, Wu Jun called him and told him that Zhou Xingchi had agreed to Cybertron Digital's request to invest in CG special effects, and as for the specific share ratio, it was necessary to continue to negotiate.

Chen Xin simply handed over the negotiation work to Wu Jun, and he and Gangyi began to prepare for the construction of the supercomputer.

Chen Xin still has a certain understanding of supercomputers.

AT PRESENT, THE SUPERCOMPUTERS USED IN VARIOUS COUNTRIES ARE USUALLY COMPOSED OF HUNDREDS OF THOUSANDS OR EVEN MORE PROCESSORS (MACHINES), SUCH AS CHINA'S SUPERCOMPUTER "TIANHE-I", WHICH USES 6144 INTEL GENERAL-PURPOSE MULTI-CORE PROCESSORS AND 5120 AMD GRAPHICS ACCELERATION PROCESSORS, WITH A TOTAL MEMORY CAPACITY OF 98TB. As for the point-to-point communication, the bandwidth reaches 40Gbps, and the total disk capacity for sharing is 1PB.

The supercomputer assembled in this way is also staggeringly large, the "Tianhe-1" supercomputer consists of 103 cabinets, covers an area of nearly 1,000 square meters, and its total weight reaches 155 tons. When Tianhe-1 is running at full capacity, its total power consumption reaches 4.04 megawatts, that is, 4,040 kWh per hour, and the power consumption is close to 100,000 kWh for 24 hours of full-load operation, and the electricity bill alone is as high as 18 million a year.

ALTHOUGH "TIANHE-1" HAS REACHED THE TOP OF THE TOP500 AT THIS TIME, THERE ARE ALSO A LOT OF CRITICISMS ON THE INTERNET ABOUT TIANHE-1, FOR EXAMPLE, THE PROCESSORS IT USES ARE INTEL AND AMD, AND ITS LINKPACK FLOATING-POINT OPERATION SPEED IS ONLY 47% OF THE PEAK SPEED.

However, this has a lot to do with the design idea of Tianhe-1.

First of all, "Tianhe-1" pioneered the architecture of CPU and GPU convergence and parallelism. Anyone who pays attention to computers knows that the manufacturers of CPU and GPU have recently competed with each other, and even shouted slogans to replace each other, but now there is a trend of convergence and development. This idea was first proposed and practiced by Chinese scientific and technological personnel during the development of "Tianhe-1".

Compared to CPUs, GPUs have a lot of excellent qualities that CPUs don't have.

GPUs consume very little energy and cost very little. Therefore, Tianhe-1 has a total investment of 600 million yuan, and if all of it is done with CPUs, it may take more than 2 billion yuan to make it. The second is energy consumption, with a total power consumption of 4.04 megawatts.

There is a green 500 ranking in the world, and Tianhe-1 is now ranked second, and each watt can produce 635.15 million floating-point operations, second only to IBM's "blue gene supercomputer" in the United States. Without heterogeneous structures, it would reach 12 megawatts. The 8 megawatts of electricity saved is equivalent to the annual electricity consumption of 5,000 households, which is still considerable.

However, GPUs are not without their drawbacks.

One of them is the reliability problem, ECC memory has no product to support so far, HPC computing is far more heavy than home computers, the requirements for accuracy are far more than game rendering, game rendering errors, it is generally difficult to be clearly reflected in the picture, players can fully tolerate it, but scientific computing can never tolerate these errors! But Tianhe-1 customers don't have to worry about such a problem, after all, there are 5120 CPUs with no problem with accuracy.

The second is the software problem, which is the biggest defect of the GPU at present, and the current commercial GPU programs are indeed a lot more than a few years ago, but compared to the HPC programs composed of general-purpose CPUs, it is still too much worse. There is still C (CUDA) available for NVIDIA GPUs, while AMDGPU is trickier, and even more famous is mailto:Folding@Home

Folding@Home, it was only because of Tianhe-1 that Linpack could be run. It can be seen that supercomputers using GPUs are likely to face the embarrassing situation of not being able to use GPU computing.

In general, the idea of using GPUs for Tianhe-1 is very haode, and general-purpose computing processors such as Fermi are also the development trend of supercomputing in the future, but the level of computing performance depends on what GPU is used! For peak performance, you can choose R700 for running a linpack; for actual performance and software support, R700 is completely untouchable.
