Supercomputing Experience on Tianhe-2

Xing Liu
Advisor: Prof. Edmond Chow


This is going to be a short talk about my supercomputing experience on the Tianhe-2 (TH-2) supercomputer, which has been the world’s fastest machine since June 2013. On Apirl 7-30, 2014, I had the opportunity to work at the Tianhe-2 supercomputing center in Guangzhou China with two others from Intel Labs. Before that, we had developed several distributed applications, which scaled very well on smaller clusters. We had been working on those applications for a long time and thought our codes were ready to be run on Tianhe-2. However, what really happened shows us that developing codes for a supercomputer as large as Tianhe-2 is more complicated than we thought and may be beyond our skills or abilities. In this talk, I will show my experience of using Tianhe-2 and hope you will find it interesting and useful.


Xing is a PhD student in Computational Science and Engineering (CSE) at Georgia Tech, supervised by Prof. Edmond Chow. Previously, he was a Staff R&D engineer at IBM STG Lab from 2006 to 2009. Xing’s research focuses on the invention of novel parallel numerical and discrete algorithms for solving real world scientific and engineering problems on emerging high performance architectures, including high-end multicore processors and accelerators. He is particularly interested in the areas of quantum chemistry and large-scale molecular simulations. His work also involves evaluating and analyzing some fundamental computing workloads and kernels, such as SpMV. This is due to the fact that these kernels are usually the computational bottlenecks in real world scientific problems.
