The simulations came "closer than ever" to modelling real crystalline silicon material behaviour and true properties in various conditions, said Dr. Wenlai Huang, research associate at CAS-IPE, who noted that the simulations take less time and money than experimental exercises.
"Computer simulations are critical to the study of new materials and production methods as it can reveal far more details than experimental measurements, at much less cost", stated Dr. Wenlai Huang, research associate at CAS-IPE. "The levels of performance we achieved by using all 7,168 NVIDIA GPUs in the Tianhe-1A supercomputer enabled us to run simulations that come closer than ever to reproducing the behaviour of the material in different aspects and its true bulk properties under different conditions, which are more meaningful for engineering and industrial purposes."
CAS-IPE research in this field is ongoing and new world records in the sustainable performance of molecular dynamics simulations are expected by the institute. Members of the CAS-IPE research team will present the research at the GPU Tech Conference (GTC) in San Jose, California, May 14-17, 2012, and at GTC China, December 15-16, 2011 in Beijing.
NVIDIA expertise in programmable GPUs has led to breakthroughs in parallel processing that make supercomputing inexpensive and widely accessible.
Tianhe-1A, located at the National Supercomputing Center in Tianjin, China, was named the world's fastest supercomputer in November 2010 by the Top 500 organization, the first time the title was given to a Chinese supercomputing centre. In addition to the CAS-IPE led research, it is being used to explore the areas of oil exploration, drug discovery and weather modelling.
