Demon School

The data generated by the experiment will be jointly completed by global cooperation units. Of course, cooperation units with strong strength, advanced equipment and sufficient manpower will undertake a larger share of the work. Those cooperation units with weak strength, old equipment, insufficient manpower or ordinary personnel quality The share taken will naturally be less.

As for the number and number of these cooperative units, an example can be used to illustrate, you can go online to find cern papers, and then you will find that the author list of some papers is outrageously long, if I put the author list and the unit list Translated, then the book's 4,000-word guaranteed update every day is complete!

And not every staff member involved in the experiment is qualified to sign on the paper, you must have a certain position in the experimental group; so behind these long heinous lists, there are far more grassroots than this The efforts of scientific researchers; the cost of high-energy physics experiments is evident from this.

Because of Professor Lu Qiujian ’s participation in the laboratory of Professor Xuft, the share of tasks undertaken has increased a lot compared to the last time; the increase in the tasks undertaken proves that his laboratory ’s status in the international high-energy physics session has increased. So despite the increased workload, Professor Xuft is still very happy.

"You will work harder during this time, and I will apply to the school to allocate some interns and logistics staff to help!" Of course, the core work can only be done by Lu Qiujian, Dietrich, Ludwig, Karl and Frei Derek and others completed it. Looking for an intern just to save them from the most basic physical tasks; as for the logistics staff, their main job is to help these people make tea, make coffee, clean the hygiene, order takeout, etc. Free them from daily chores, so they can devote themselves to data analysis.

"Lv is responsible for arranging and managing the daily work, and then Lv summarizes the results of each stage to me!" Professor Xuft delegated the management power to Lv Qiujian. Of course, the use of the new method may not be found globally. To someone better than him.

"Okay!" Lu Qiujian did not give way, which is also an exercise for himself.

"No problem, we will obey Lu's instructions!" Although Lu Qiujian is the youngest in the laboratory, the ability demonstrated by Lu Qiujian in the previous stage of work has completely convinced them. They had absolutely no opinion on Professor Xuft's arrangement.

"So let's get started!" After Professor Xuft went out, Lv Qiujian began to take over the command of the laboratory, splitting the work into several links and assigning to Karl, Dietrich and others.

Half an hour later, Professor Xuft returned to the laboratory with the brigade. A group of young teenagers excitedly looked at the equipment and their seniors in the laboratory; especially Lu Qiujian received the most attention. His Mingrui hearing can hear the group of teenagers spit out "Bayern" from time to time. , "Free Fight" and other words.

For their work, Lu Qiujian had already arranged it just now. Karl and others stood up and briefly asked about their basic situation, and then divided into several groups, and then led a group to start the basic training before work.

This situation is happening at the same time in research institutes all over the world, from the United States to the neon, from China to France, from Italy to England ... A famous laboratory has been busy.

When 4 large detectors such as atlas and cms started working with 10 times higher accuracy than any previous tool. Will produce a pile of data. If scientists want to find what they want, this computer power is necessary.

These detectors are like a huge digital camera with 150 million pixels that can shoot 600 million times per second. They record every detail of the crash test and then send it to the center of the computing grid of the cern; precise The filter will filter out all useless data, leaving only the most interesting data. However, 15 pb (each pb is equal to 1024 tb) data still needs to be analyzed each year, which is enough to fill up 2 million DVDs.

Then the task of 150 cooperative units distributed around the world is to analyze the huge data that can fill up 2 million DVDs; cough, if you compare the data in these DVDs to some kind of movie that you like to see, a otaku is ten seconds faster After finishing one, then it would take 231 days for him to eat, drink, pour, sleep, or go to the bathroom.

Therefore, although cern's experiment is over. However, it would take a long time to know whether the Higgs boson was produced in this experiment; but with the new method provided by Lu Qiujian, this time has been much shorter than originally planned.

If the collision test is colorful and exciting, then the data analysis is boring and tasteless. This is the same as other scientific experiments. The wonderful is just a moment. More often, the staff needs to calm down to pass the boring process. Discover something wonderful.

It can be said that there is no Internet invented by Bonas-Lee ~ www.readwn.com ~ these tasks are not so easy to carry out; it is precisely because of today's developed network and increasingly updated computer technology, coupled with the completion of high-energy physics Here comes a new spring.

If there is no Internet, then even if it is completed and completed the collision experiment. Then the next data analysis work will either concentrate scientists from all over the world to cern for data analysis; or ship the data to cooperative units around the world in various ways. Damn it!

Wait for the completion of these data analysis and then summarize them to cern. If cern finds any errors or omissions in the data analysis. The data processing unit has to be returned again, so a lot of precious time is wasted on the road! Not to mention the huge cost of shipping data!

Cern's research has promoted the development of science and technology, and the development of science and technology has provided more efficient tools for the research of cern, which is a virtuous circle.

David Collin, a scientist at Imperial College London, said of the computing grid hub, "The grid is the third generation of the Internet, but unlike the Internet, you are sharing the power of a computer, not files. No This kind of infrastructure is not possible with experiments. This is why particle physicists attach so much importance to the center of this computational grid. "

And now, more than 150 cooperative units around the world are conducting data analysis of this collision experiment through this grid hub. They are busy day and night in order to find some before other cooperative units. What a surprise! (To be continued.)
