Jointing the world first, breaking the world record!How does this average 24 -year -old team do?

Text ｜ "China Science News" reporter Wen Cai Fei

"Based on the latest ranking of the Graph 500 just released, our team's map computing system once again ranked first in the world in the shortest single source path (SSSP), and exceeded all distributed systems with a single machine performance. Congratulations on the laboratory friends! "After learning the results, as the leader of the team, Jin Hai, a professor at the School of Computer Science and Technology of Huazhong University of Science and Technology, forwarded the good news in the WeChat group.

On the same day, when Children's Day, at the moment when they saw the results, the students were so happy that they returned to their childhood. "First, we kept the first."

Not long ago, the 24th Graph 500 ranking was announced at the International High Performance Computing Conference. , Also broke the world record.

High -performance map calculation is known as the next technology forefront, but who can think that it means that the average age of only 24 years of age is only 24 years old.

Talent training should be "urgent in the country"

Figure calculations listen to strangeness, but it is inseparable from its application in life.

I just bought a product, how to push the advertisement to B with the same interest? Suddenly there is a large number of electricity needs. Use a taxi software to navigate from one place to another, how to find the shortest path? Native

To solve these problems, they will be used to graph calculation technology. In addition, this technology is widely used in civilian and military fields such as fintech, Internet application, drug screening, and breeding screening.

In 2009, Google first proposed the concept of figure calculation. Since then, the United States, Japan and other countries have successively invested heavily in research. And China later went up, anti -overtaking in the United States, leading the world. An important evidence is the continuous refresh world record of Huazhong University of Science and Technology. The research results of the domestic Tu computing school have successively boarded the top international academic conference.

What are the mysteries behind the world's number one? "Behind the" First "is the first goal of the school with talent training." Jin Hai said.

In this team, how to cultivate excellent students, urgent the country's urgent and dare to stabb the bones, must be considered by Jinhai. He does not support the study of "from Paper to Paper". When opening the question, if some students do such a study, they will often send cash teachers "expressionless". On the contrary, the real question is really appreciated by him.

"The problem must come from the industry. If you want to do the research of" thinking about the country, the urgency of the country, the need for the country, the need for the country's need ', to lead the international cutting -edge and solve the' card neck 'problem, because only from the bottom level Principles innovation and excessive existing technology will not be subject to others. "Jin Hai was very determined.

In 2018, the "General Computer Technology and System" project led by Huazhong University of Science and Technology was included in the national key research and development plan. The school also established a joint laboratory with Huawei and Zhijiang Laboratory to cooperate with top domestic companies such as Tencent and Ali.

"Master students and doctoral students can access the topic of national key R & D plans, and suddenly open our horizons, allowing us to integrate with the industry during the start of scientific research and develop useful results." Zhao Jin, a doctoral student with the School of Technology.

Zhang Yu, an associate professor at the School of Computer Science and Technology of Huazhong University of Science and Technology, told the China Science Journal of Computer Science and Technology, and compared with previous students, there are more opportunities for students to contact the industry. "In the past, students occasionally had the doubts of whether the results met the needs of actual production, but now they can send the article to the top international conference and apply the results to the enterprise."

Create the cultural atmosphere of cultivating innovative talents

Speaking of educating people, Jinhai has "three moves". The first move is to encourage students to solve the real problems; the second trick is to give students a loose and free environment; the third trick is to create a good team culture. The "three moves" sound flat, but it is really "powerful."

"Our research content can be found by ourselves. The mentor will not ask students what to do. Instead, it supports the direction of our own interest. It will be very energetic when doing this." Zhao Jin said, he himself Regarding the direction of "independent development" "facing the hard and hard -and -hard optimization technology calculated by the picture", Zhang Yu helped him contact his foreign counterparts, and encouraged him to "do one thing and do not waste halfway, and persist."

After cooperating with the enterprise, Zhao Jin came into contact with engineering management thinking. In their cooperation with Huawei, they have to report the project progress every two weeks. About half a year, Huawei will accept and test their code. "We want to explain how the code is written, which has exercised the ability to express and communicate." Zhao Jin said.

"In the university, the cultural construction and incentives of the team are also an important part of education." Jin Hai said. The laboratory runs a journal of internal exchanges- "Parallel and Distributed Calculation Communications". Although it only issued 4 issues a year, the cover characters of each issue are students who published articles at top academic conferences. "Whenever the students publish articles in top academic conferences or journals, Teacher Jin will publish and congratulate in the nail group." Not long ago, Zhao Jin also received the congratulations of Jinhai. Unusual pride.

The laboratory also has its own WeChat public account- "through the jungle." It will publish articles published by laboratory members in top academic conferences and journals, and in popular science in popular language. The latest issue of tweets is recommending the research results of Zhao Jin and Zhang Yu's "IEEE TKDE22: GPU -based dynamic diagram processing system".

The "thick foundation" makes the future more likely

Shen Qiange is a graduate student who just joined the picture calculation team this year. She studied under the undergraduate School of Computer Science and Technology of the University of Science and Technology of China, and has not participated in such a specification game before. The feeling of "debut is the pinnacle" made her feel "dreamy." "On the day when I saw the result, some of our friends who studied one was unbelievable. They put down what was doing in our hands, and saw the results over and over again."

With the World Championship for students to "train" students, what is the confidence in the school?

Feng Dan, dean of the School of Computer Science and Technology, Huazhong University of Science and Technology, said that at the undergraduate stage, the School of Computer School pays special attention to the training of system capabilities. Students should go through "designing a CPU, an operating system, a compiler, a database" to the seventh The semester is a monthly comprehensive practice training. Now the college's talent training system has also been fully integrated into the domestic IT ecosystem, and the introduction of domestic IT ecological root technology such as Huawei Kunpeng, Shengteng, Hongmeng, and Dimeng Database into textbooks, classrooms, and experiments to achieve the cultivation of system capabilities to IT ecology. Upgrade of stack system capacity cultivation. "Students have fully contacted and learned the use of domestic IT ecological roots at the undergraduate stage, so they also laid a solid professional foundation."

"Don't underestimate the strength of students. Because they are" refined '. "Zhang Yu said that although the students trained in this way do not know what is calculated when they first arrived, they had to get started after contacting cutting -edge knowledge. quick.

It is due to the foundation that usually laid, last year's map computing team also won the national gold award of the 7th China International "Internet+" College Student Innovation and Entrepreneurship Competition. Unexpectedly, this is the result of more than a week when they encounter bumps when they are writing code.

"We ca n’t calculate the preparation time, because we have been doing high -intensity realistic projects, and the foundation we have laid during this time can actually be considered 'preparations'." Zhao Jin said with a smile.

"For computer disciplines, the" thick foundation 'is very important. Because its knowledge is updated very fast. However, it is inseparable from its ancestors and consolidate the foundation of the core lesson. If so.
