6月20日，ISC12世界大学生超级计算机竞赛在德国汉堡落下帷幕。由清华大学计算机系的徐世真等6名大四学生组成的清华代表队获得了本届比赛总冠军。这是中国大学生在国际超级计算机竞赛中取得的第一个世界冠军。

June 20,，The world university ISC12 super computer competition to drop the curtain in Hamburg, Germany。By tsinghua university in the department of computer science and XuShiZhen six senior student of composition tsinghua team won the championship game。This is China's college students in international super computer competition is achieved in the first world title。

　　"我们比较幸运"，队长徐世真谦虚地总结这次比赛。然而，成绩背后凝结的是6名队员和指导老师的汗水和智慧。

"We are fortunate"，Captain XuShiZhen modest up the game。however，Scores of condensation is behind six players and guide teacher sweat and wisdom。

应邀参赛：是机遇，也是挑战 Invited to the：Is an opportunity，Is also challenges

　　今年2月，计算机系高性能所的杨广文老师找到了徐世真，希望他能参加这次超算竞赛。徐世真又找来了了吕子鉷、廖俊峰、程芃祺、任一恒、杨弋等5位同学，组建成了清华代表队。

February，The computer of high performance of the YangGuangWen teacher found XuShiZhen，Hope he can take part in the super calculate competition。XuShiZhen and find it LvZi Hong、LiaoJunFeng、ChengPengQi、RenYiHeng、Various Yang five students，Form a tsinghua team。

　　徐世真同学以超算为今后研究生期间的研究方向，参加本次比赛是一次难得的机遇。当被问到为什么选择超算时，他表示主要原因是老师的影响和个人兴趣，他说："不同的人有不同的选择，我觉得做这个就挺有意思。"

XuShiZhen students is super for future research direction of graduate student period，Participation in this race is a rare opportunity。When asked why choose super calculate，He said the main reason is the teacher's influence and personal interests，He said："Different people have different choice，I feel that this is very interesting。"

         而对杨弋同学来说，具体研究方向不同，课外工作压力繁重，比赛本身又需要耗费大量时间和精力，等待他的是对能力和毅力的双重挑战。 

         Yang and various for students，Specific research direction is different，Extracurricular work pressure heavy，The game itself and the need to spend a lot of time and energy，Waiting for his ability and perseverance to double challenges。 

努力备战："不知不觉的，天亮了，十点了" Efforts to prepare for the："Before you know it，At dawn，Ten o 'clock"

　　当6位同学正式着手准备比赛时，他们发现真正的挑战比预想中要严峻得多。

When six students begin to prepare for the formal game，They found that the real challenge than expected to severe in。

　　本次竞赛的赛事规则要求各参赛队在3000瓦功耗下，自行设计搭建系统，并进行浮点计算性能测试，及分子动力学、海洋环境等多个大型应用的算例测试。

The contest of the rules of the competition teams in the power consumption of the 3000 watts，Set up his own design system，And floating point calculations performance test，And molecular dynamics、The Marine environment, and other large application examples。

　　参加ISC12之前，要先经过国内的初赛和决赛。初赛的准备时间只有两周，决赛的准备时间也只有不到一个月。这期间，队员们几乎天天在实验室工作12小时以上。为了做到心中有数，队员们专门请教了经验丰富的兄弟院校的教授，也了解了对手的基本情况。

To ISC12 before，After the first domestic preliminaries and final。The preliminary preparation time just two weeks，The final preparation time is less than a month。During this，The players in the laboratory work nearly every day for more than 12 hours。In order to do fairly well，The players special consult the rich experience of other colleges and universities professor，Also learned the basic situation of the opponent。

　　整个准备过程中最困难的是一头一尾。开头难，是因为要在两三天内熟悉一个非计算机专业的大型应用，要充分了解程序原理、应用背景、编译运行过程、输入输出内容。而准备到最后会遇到瓶颈，"你优化一段时间，就发现优化不下去了。可能偶尔快了百分之二，也完全可以用误差来解释。天天在熬时间，就感觉没有办法再优化了。"

The preparation process of the most difficult is a head of a tail。Difficult to start，Because in two or three days to within a not familiar with computer professional large application，To fully understand the program principle、Application background、Compiler operation process、Input/output content。And going to finally will meet the bottleneck，"You optimization for a period of time，He found that optimization not bottom go to。May occasionally fast two percent，Also can use error to explain。In cook time every day，It felt no way to optimize。"

　　于是，"不知不觉的，天亮了，十点了"这样的状态常常出现在队员们的网上状态中。

so，"Before you know it，At dawn，Ten o 'clock"Such a state often appear in the state of the players online。

小试牛刀：首战告捷，出奇制胜 NiuDao was：A good beginning，Surprisingly winning

         国内决赛一开始，由于环境和他们预想不同，机器运行几乎要超过规定的3000瓦。即将到达规定值时，机器运行出了结果。回忆起当时，徐世真直呼"很惊险"。  第二部分比赛，"惊险"没有结束。由于错误估计运行时间，比赛开始两个小时后，他们发现算例不能全部运行完。于是他们进行了两次大的调整，这使得他们多完成了两个高质量的算例，同时这也成为之后在答辩中留给评委印象最深刻的部分。

         Domestic final a start，Due to different environment and they thought，The machine runs almost want to exceed the 3000 watts。Will arrive when rating，The machine runs out of the results。recall，XuShiZhen call"dangerous"。  The second part of the race，"breathtaking"Not over。Because to mistake running time，Two hours after the game，They found that example can't all after operation。Then they made two major adjustments，This makes them more completed two high quality calculation example，It may also be the defense after left the most impressive part of the judges。

         之后第二天的比赛直接确定了胜利，由于在比赛之前发现一个应用中一个非常大的改进，他们在这个应用上的得分甩开了其他对手。当天晚上他们就开始庆功了，虽然在很轻松的氛围中做答辩PPT，但黄老师要求很严格，第三天，他们获得了答辩的第一名。

         The second day after the game to directly determine the victory，Because before the game found a application of a very big improvement，They in this application of beating the score on other rivals。That night they began to celebrate，Although in very relaxed atmosphere do rejoin PPT，But the teacher is very strict，The third day，They won the reply of the first。

         赛后他们与其他队伍交流。"我们可能主要就是赢在对应用的理解上"，由于每个人都负责一个应用，而应用间存在共同点，充分交流及广泛搜集资料使得他们对于应用的理解大大加深。

         After the game they and other team communication。"We may mainly is to win in the understanding of the application"，Because everyone is responsible for an application，And the use of exist between the in common，Communicate and widely collected material makes them for application understanding greatly deepened。

稳中求胜：德国决赛，震惊世界 Stability will to win：Germany final，Shocked the world

         由于并非本土作战，在世界决赛前搭建系统的环节，除本地的学校之外，其余代表队都出现了接触不良、硬盘无法匹配等问题。美国部分大学甚至在第二天比赛前仍未搭建好系统。清华代表队也不能幸免。他们花费了一整天的时间甚至求助了赞助方工程师才完成搭建。赛前清华并不被看好。德国的队伍使用了赞助厂商特殊的设计和很多顶尖设备，集本土作战优势，被认为最有可能夺冠。

         Because there is not local operations，In the world before the final build system link，In addition to the local school outside，The rest of the teams appeared contact undesirable、Hard disk can't match。American university in the second day of even before the game is still not build good system。Tsinghua team also can't miss。They spent a whole day even turn to sponsor engineer to finish building。Pre-match tsinghua does not favor。The German team use the special design of support from manufacturer and many top equipment，Set native combat advantage，Is considered the most likely the title。

　　尽管如此，有了国内决赛的经验和对应用深入的理解，清华还是得到了冠军。特别是在OpenFoam这个流体力学的应用上，他们几乎将运行效率翻了一倍。这个成绩大大出乎了主办方的预计，震惊了超算界，甚至因此给他们颁发了一个特别奖项。

Even so，With domestic final experience and understanding of the application，Tsinghua or won the championship。Especially in OpenFoam this fluid mechanics applications，They will run efficiency almost doubled。The result was quite beyond the organizers expected，Shocked the super calculate boundary，Even so they presented a special award。

　　随着比赛的落幕，6位参赛队员也结束了大学生活。由于出国参加比赛，6位队员都错过了毕业期间的各种集体活动，这成了他们心中的遗憾。"听说班里同学已经收拾行李准备毕业旅行了，心里涌上一阵阵伤感"。比赛结束后各个队员连夜给父母、老师、辅导员写了很多明信片，表达感恩之情。

With the game in the end，Six players also ended the college life。Due to go abroad to take part in the game，Six players have missed during the graduation activities，This became the regret of their hearts。"Heard that students in the class has packed for a trip，Heart poured into the waves of sadness"。Each night after the game players to the parents、The teacher、Instructors wrote many postcards，Express gratitude。

　　但遗憾之余更多的是收获，分工合作让他们备赛中在充分交流中相互学习；在比赛中，更是提高了临场应变的能力。同时他们希望以此次胜利为契机，吸引更多的计算机人关注中国超算领域的发展，并加入到发展超算的队伍中来，希望中国超算领域早日突破应用瓶颈。

But regret more than the more is to harvest，Cooperate let them in exchange for in full of learning from each other；In the game，More is to improve the in-game adjustments ability。They also hope to the victory as an opportunity，Attract more attention to China's super computer is the development of the field，And adding to the development of the team，Hope China super calculate field early breakthrough application bottleneck。

　　其实在准备比赛的同时，他们就已经成立了SIG-HPC小组（高性能计算兴趣小组），希望以此为契机，让更多的同学加入小组，了解超级计算机的发展及相关应用。同时他们也十分期待其他院系的同学的加入。

In fact in preparation for the game at the same time，They have set up SIG-HPC group（High performance computing interest group），Hope that this as an opportunity，Let more students join groups，Understand the development of the computer and super relevant application。At the same time they also looked forward very much to other departments of the students to join in。

前景展望：应用广泛，任重道远 prospect：Wide application，Still has a

　　谈及对超级计算机领域的看法，队员们告诉我们，超级计算机涉及的领域很多，比如在海洋、石油、金融方面的应用，而且超级计算机在各个领域方面的应用是相互联系的，各模式是相通的。超算人才发展方向多，未来有很多种选择。

It comes to the super computer field of view，The players tell us，Super computer operating in many，For instance in the ocean、oil、Financial aspects of application，And the super computer in various fields of applications are connected with each other，Each mode is the same。Super talent development direction is，The future have more choices。

　　但是中国在超算领域的发展仍任重道远，比较缺乏应用方面的人才，重点在于缺乏学科交叉的综合复合型人才。现阶段国家也在大力宣传超算的应用领域。目前，清华大学计算机系将超级计算作为未来重点发展的三个方向之一。

But China is in the fields of development is still a long way to go，The relative lack of application talents，Key in a lack of discipline overlapping comprehensive talents。At present the country is the publicity of super calculate application fields。At present，Tsinghua university computer department will super calculation for future focus on the development of one of the three directions。
