Outline

• Background of China HPC TOP100 • Analysis of 2011 China HPC TOP100 • Overview of China 863 key project • Petascale Applications on TianHe-1A • Future HPC performance development

trends of China • Summary

• With correct strategies, China wins the HPC Olympic Games on 2011, and HPC is really helping science and economy development of China.

• HPC real application still lag behind the US, Euro and Japan.

• On TianHe-1A, several applications can scale up to 80,000 cpu cores.

• The growth rate of China HPC Perf. Is the fastest. • There will be at least 19 major petaflops

supercomputing centers within 5 years.

Summary

• First Petaflops supercomputer totaly powered by domestic processor designed by China has been released on HPC China 2011@JiNan;

• According to TOP100 predictions, 10 Petaflops peak performace supercomputer will appear before 2013;

• According to TOP100 predictions, 100 Petaflops peak performance supercomputer may appear before 2015;
