Research starts with PhD students

Chapter 23 Just start the device and run it!
After making the report at the experimental base, the acceptance team took Zhang Shuo and Luo Yongjun to the computing center of the Institute of High Energy Physics.

On the way, Bao Hexing was still talking about Zhang Shuo in front of Liu Ye, "Let's not talk about research issues, his algorithm level is too good."

"He used the simplest and most effective method to split the modules in the framework into package algorithms. Even I couldn't do better."

"And he has a PhD in mathematics. Mathematics is the foundation of computers. If you are good at mathematics, you will have great potential for development in computer research."

"It would be a shame if such a talent didn't join the computing center..."

Liu Ye nodded continuously as he listened, and then said, "I also know that Zhang Shuo is a talented person. This research is a comparison between experiments and simulations. I haven't even thought about it, let alone doing it."

"But he has just entered his first year of doctoral studies, and his research is much more important than the level of algorithms. I think he is more suitable for the Physics Experiment Center."

"You're not trying to rob someone, are you?" Bao Hexing looked over cautiously.

Liu Ye laughed. "No matter what we say, it's useless. It seems Zhang Shuo has never considered it, or he simply doesn't want to come."

Zhang Shuo and Luo Yongjun were in another car.

Luo Yongjun was also talking about the same topic, but he was regretting Zhang Shuo's rejection, "What a great opportunity! He will be an associate researcher once he gets in."

"That's the computing center of the Institute of High Energy Physics. It's better to enter as a special talent, so you can save ten years of hard work..."

"I almost agreed to it for you just now!"

He kept shaking his head as he spoke, "If you stay in school or go to work in other universities. Now it's a promotion or leave system, and it depends on your research results."

"Of course you should be fine..."

Zhang Shuo smiled nonchalantly and said, "Didn't Professor Bao just say that I can go anytime? I can think about it when I'm about to graduate."

"Who can tell what will happen in a few years? By then, it may not be considered special talent treatment. It's OK to sign the contract now."

"I didn't want to go."

Zhang Shuo shook his head and said, "Actually, I'm not good at studying computer algorithms. I only do this because it's necessary for research."

"You're not good at it yet?"

Luo Yongjun complained a lot in his mind, then changed the subject and asked, "Have you thought about what you want to do in the future?"

"Research work related to mathematics and physics."

Zhang Shuo affirmed, "I am interested in theoretical physics and hope to do relevant experimental research in the future."

"High-energy physics experiment?"

“It is an experiment to study theoretical physics and verify physical theories.”

Luo Yongjun pursed his lips tightly and thought for a long time but still couldn't understand. He frowned and asked, "So, you still want to join the Institute of High Energy Physics?"

"Why do you say that?"

Zhang Shuo was puzzled.

Luo Yongjun explained, "The Institute of High Energy Physics' Theoretical Physics Research Center is the leading academic institution in the field of theoretical physics in China."

“There are very few scholars in the field of theoretical physics.”

"As far as I know, most professors in university physics departments are engaged in optics, condensed matter physics, plasma, quantum physics, etc."

"I'm engaged in research on string theory, dark matter, cosmology, etc. I've only heard of them, but I don't know any of them..."

Luo Yongjun said this and shook his head secretly.

He couldn't understand why he was interested in theoretical physics. Take the funding issue for example. Theoretical physics is a worse subject than mathematics!

……

Bao Hexing took Zhang Shuo and Luo Yongjun to visit the computing center.

The computing center is a very large scientific research institution, engaged in multi-directional research in high-energy physics scientific computing, data storage, networks, scientific research informationization, scientific application software, etc.

The computer cluster it owns is the largest high-energy physics data platform in the country.

The center's data processing platform supports data processing and analysis of the Capital Collider experiment, cosmic ray experiments, Daya Bay neutrino experiments, and the Large Hadron Experiment at CERN in Geneva, Switzerland.

They visited the High Energy Physics Science Data Center and the auxiliary computing room located on the underground platform.

Bao Hexing introduced that "the deputy computing room can temporarily provide additional computing power for the main computing platform."

"It is usually used for research on big data analysis and computing. Researchers can use the computing power here to solve some complex computing problems."

"The equipment here is sufficient to support experimental data analysis." "According to my estimate, only half of the equipment needs to be turned on, and all the calculations can be completed in less than two hours."

During the introduction, he kept talking about the scientific research conditions of the Computing Center, and it was obvious that he still wanted to persuade Zhang Shuo to work in the Computing Center.

After the tour, they went to a studio and discussed issues related to the program input.

The input end still needs to be modified so that the required experimental data can be directly called and entered into the program.

This is the main job.

Zhang Shuo learned about the experimental data and communicated with several researchers and decided to start the program modification work tomorrow.

The acceptance team invited Zhang Shuo and Luo Yongjun to rest in the hotel.

This reception was wonderful.

They were arranged to stay in a luxury hotel near the computing center. The hotel was located in the center of a lake, and they felt refreshed just by taking a walk around the hotel.

Luo Yongjun took a selfie with his phone and took a photo with Zhang Shuo. He sighed with excitement, "It's not so good to travel on government funds!"

“The Institute of High Energy Physics is really rich!”

"I must post it on WeChat Moments..."

He operated his phone for a long time before looking up and asking, "Zhang Shuo, I see you rarely take photos and never post to Moments, why is that?"

"There's nothing to post."

Zhang Shuo shrugged indifferently.

If he posts on WeChat Moments, there will definitely be a bunch of people asking questions.

It feels good to be cared for, but many people ask about project issues, and some just gossip. He doesn't even bother to reply to the messages.

……

After resting for a night in the hotel, I officially started working the next day. My work was to modify the input and output ends of the program.

Zhang Shuo didn't do it himself.

He just explained the program input and calculation port, and the people involved in the acceptance made modifications spontaneously.

They were all professional computer researchers, so it was very easy for them to modify the code. The input problem was solved in just one morning.

In the afternoon, all work revolves around the output end.

The output code written by Zhang Shuo is too sloppy. It is just a bunch of pictures with particle points marked with different colors. It is not easy to understand.

Several researchers took the algorithm packages they had compiled and directly embedded them into the output program, allowing it to perform a series of analyses on the output data.

Including regional location comparison, computing intensity comparison, and a series of other data.

You can even draw a picture of the experimental process and put it together with the simulation picture to clearly see the difference between the two.

At four o'clock in the afternoon, the modification work on the input and output ends was completed.

Then it is ready to debug and run.

Debugging operation is to directly enter the experimental data in batches. If there is a problem in the initial entry, you can pause and modify it, find out the problem, and then enter it again.

In other words, debugging is done directly based on experimental data.

Several researchers who participated in the program modification work were very confident in the debugging and running. They said to Bao Hexing, "No problem, it will pass in one go."

"We have debugged each module group in the program separately, and the functional implementation process is very smooth, and no obvious bugs have been found."

“Just turn on the device and run it!”

soon.

The equipment in the auxiliary computing room is turned on.

The program was entered into the main computer and the experimental data docking program began to run.

A large group of people gathered around the large screen hanging on the side.

The output screen will slowly appear above, with each point forming an image, and you can clearly see the difference from the simulated image behind.
