Top spot in international supercomputing challenge

NTU students take top spot in international supercomputing challenge

In the world of supercomputing, some consider taking part in the student cluster competition at the Supercomputing Conference (SCC) 2017 a major achievement.

But in only its second time participating in the competition held in the United States from Nov 13 to 15, Nanyang Technological University (NTU), represented by a team comprising six undergraduates, bagged the top prize.

It beat 15 others from around the world, including top universities like the Georgia Institute of Technology, Taiwan's National Tsing Hua University and China's Tsinghua University.

The team from NTU's School of Computer Science and Engineering had to configure a high performance computing (HPC) system that can understand and process complex scientific applications that were issued to them in mid-August.

For instance, the system may need to run applications that can detect oil and gas in the sea, or analyse a given sequence of DNA, which can take between eight to more than 30 hours to process.

But the team only had 48 hours during the conference in Denver, Colorado to build their system and run the applications.

To challenge them further, all teams were also given a mystery application at the start of the conference that their system had to process as well. The NTU team had to configure a softwareto simulate the Earth's atmosphere.

When the competition started on Nov 13, the teams worked feverishly around the clock to configure HPC systems that would allow four applications to run smoothly and efficiently.

While the HPC systems they built are not supercomputers, which refers to a system that performs at or near the currently highest operational rate for computers, they do draw on the same HPC technology.

The NTU team advisor Associate Professor Francis Lee said the students employed a maverick strategy by packing more computing power into fewer individual computers in the cluster, known as nodes in a HPC system.

While most teams used only eight graphic processing units, the NTU team used twice the number, but packed them densely into just two nodes. This was because the team was able to get access to more graphic processing units, sponsored by technology firm Nvidia Singapore.

"Previously, we didn't have the computing power to match, but this year we packed (two nodes) with 16 of these units and made it really powerful," said Prof Lee from NTU's School of Computer Science and Engineering.

The students also consulted domain experts to better understand the science behind the applications, including the Earth Observatory of Singapore, which made it easier for them to optimise the applications for the HPC system they built.

Among other things, judges appraised them on their presentation skills, and how well they understood and executed the application software.

The National Tsing Hua University and Tsinghua University were placed second and third respectively.

NTU had also entered a team in 2016 for the SCC competition which has been running since 2007. The team was sponsored by the National Supercomputing Centre Singapore (NSCC).

Team captain Liu Siyuan, 21, a fourth-year computer science student, said that the SCC competition tested the the students' skills in many aspects.

"First of all, we had to understand the applications and the maths behind them, and we also needed to have enough coding skills to change the codes of these applications (so that they can run fast on our computing system)."

While the team did not win any prize money, Prof Lee said that their victory has placed Singapore on the map in the growing field of supercomputing.

NSCC deputy director Jon Lau said: "With this achievement, we have shown that Singapore is on track towards building strong HPC competencies among our institutions of higher learning."

全球大学就业力排名 南大排名提升至第91

全球大学就业力排名国大微跌至16 南大排名提升至第91

新加坡国立大学在一项全球大学就业力排名中,名列第16,比去年下滑一个名次,是唯一跻身前20名的本地大学。

《泰晤士报高等教育特辑》本月16日发布2017年全球大学就业力排名(Global Employability University Ranking),了解各大学毕业生的受雇能力,排名工作今年步入第七年,共有150所大学入榜。



2017年全球大学就业力排名(Global Employability University Ranking)。

排名由法国人力资源机构Emerging设计,德国市场研究公司Trendence进行。全球约6000名招聘经理参与调查,受访问题包括,他们认为哪些大学培养最具备工作能力的毕业生、所重视的特质等。

国大副校长(学术事务)兼教务长陈永财教授说:“国大很欣慰我们的毕业生能继续获得全球雇主的青睐,这体现国大变革型教育的进展,强调学术水平、体验式学习、培养国际观、同职场需求挂钩等,为毕业生提供良好的就业前景。国大会继续栽培能面向未来的毕业生。”

全球方面,美国大学的整体表现最佳,150所入榜的大学中,美国大学占35所。入榜的前10名以美国学府为主,加州理工学院蝉联榜首,第二名与第三名分别是哈佛大学以及哥伦比亚大学,哥伦比亚大学今年更是跃进九个名次。

亚洲大学方面,日本的东京大学表现最佳,排名第九,其次是香港科技大学和北京大学,分别排名第12和第14。

《泰晤士报高等教育特辑》信息部主编西门贝克(Simon Baker)说,亚洲大学的整体表现都有所进步,它们着重于培养学生新时代所需的技能,包括协作能力,并在学生毕业前就让他们有机会接触业界。

除了国大,另一所入榜的本地大学是南洋理工大学。南大今年排第91,比去年高10个名次。

本地三所大学毕业生 就业率维持在八成以上

根据国大、南大和新加坡管理大学今年2月公布的毕业生就业调查,三所大学毕业生的整体就业率仍“维持在高水平”。去年在毕业后半年内找到工作的大学生比率略微增加,从前年的89.5%增加至89.7%,同时期毕业生全职就业率则只有80.2%,低于前年的83.1%。
