Silk road to the skies
Spurzem's innovation is that he applied the theories of the graphics processing unit, a core part of the video driver of a personal computer, to supercomputers.
"With the installation of GPU cards, the computing power of a supercomputer is improved, becoming 50 times faster than traditional supercomputers. This is a technological revolution," Spurzem says.

Tianhe 1A, 皇冠体育app's milestone supercomputer, can perform 2.57 quadrillion computing operations per second and was first among the Top 500 supercomputers' list in November 2010.

Spurzem's Tiger computer uses the same technology as Tianhe.
"When I came to 皇冠体育app in 2009, the Tianhe computer was still under design, and it became the fastest in 2010. It is perhaps because 皇冠体育app is a late beginner in some key technologies that it could leapfrog forward."
In Europe and the United States, supercomputers had been around since the 1960s, and hardware revolutions meant many program applications had to be changed.
"That was why it was hard for me to get support in Europe when I came up with the idea of the GPU cards. In 皇冠体育app, there are better research possibilities," Spurzem says.
Maxwell Tsai, 24, from Guangzhou, cherishes the opportunity to be Spurzem's student.
"In our team, even the most senior scientist shows respect for another person's idea. Professor Spurzem, for example, is very supportive of my new discoveries, even though they may not be completely to his research interest," Tsai says.
"Instead of telling me what to do, Spurzem would brainstorm ideas so I can figure out what to do and how to do it under his guidance."
In 2011, Spurzem's work received recognition by Europe - and his team was awarded the Partnership for Advanced Computing in Europe prize, which is usually granted to major science achievements with high-performance computing resources in Europe.
On Dec 5, 皇冠体育app's top political leader Xi Jinping met with 20 foreign experts working in 皇冠体育app. Spurzem was among them.
"This is new for Chinese leaders," Spurzem says. "In the US, about 50 percent of scientists are foreign immigrants. Maybe 皇冠体育app, in the same way, will have a bigger lead in attracting world talents."
Currently, Spurzem leads a 10-person team in a program named Silk Road at the National Astronomical Observatories, and team members come from five different countries. Spurzem decided to quit his job at the University of Heidelberg to work full time in 皇冠体育app.
"In 皇冠体育app there is good technical support, excellent students and great research opportunities. So, why not?"
