What part am I missing? The Chinese supercomputer was more than 2X faster than the US model. When you consider Mao destroyed the universities and killed the intelligentia 40 years ago and China has rebuilt to this capacity, what are they now capable of in the next 10 years?

The development of Tianhe-2 was sponsored by the 863 High Technology Program, initiated by the Chinese Government, the government of Guangdong province, and the government of Guangzhou city.[1] It was built by China's National University of Defense Technology (NUDT) in collaboration with the Chinese IT firm Inspur.[1][5] Inspur manufactured the printed circuit boards and helped with the installation and testing of the system software.[1] The project was originally scheduled for completion in 2015, but was instead declared operational in June 2013.[6] As of June 2013, The Supercomputer has yet to become fully operational. It is expected to reach its full computing capabilities by the end of 2013.[5]

In June 2013, Tianhe-2 topped the TOP500 list of fastest supercomputers in the world. The computer beat out second place finisher Titan by nearly a 2-to-1 margin. Titan, which is housed at the U.S. Department of Energy's Oak Ridge National Laboratory, achieved 17.59 petaflops, while Tianhe-2 achieved 33.86 petaflops. Tianhe-2's phenomenal performance returned the title of the world's fastest supercomputer to China after Tianhe-I's debut in November 2010. The Institute of Electrical and Electronics Engineers said Tianhe-2's win "symbolizes China's unflinching commitment to the supercomputing arms race".[5] China houses 66 of the top 500 supercomputers, second only to the United States' 252 systems.[3]

Also in June 2013, Tianhe-2 is ranked sixth on the Graph500 list of top supercomputers. In their benchmark, the system tested at 2061 giga-TEPS (traversed edges per second). The top system, IBM Sequoia, tested at 15363 giga-TEPS.[4]

Tianhe-2 will be housed at the National Supercomputing Center in Guangzhou (NSCC-GZ) in east campus of Sun Yat-sen University after the completion of the testing procedures.
