China's Tianhe-2 retains supercomputer crown

The Tianhe-2 supercomputer, developed by China's National University of Defense Technology, remains the world's most powerful computer, according to a biannual Top500 list of supercomputers.

Every year, the Top 500 list publishes a rank of the world's fastest supercomputers. This year, Tianhe-2, a massive computer system, takes the trophy and makes China as the country with the fastest supercomputer in the world.

This is the third time for Tianhe-2, also known as the Milky Way-2 to top the list. With 54.9 thousand trillion floating point operations per second, Tianhe-2 is almost twice faster than "Titan" of the US, which ranks at the second place. It's highest operation speed per second equals to 1.3 billion people using calculator non-stop counting day and night for a thousand years. The computer system can be widely used in many areas such as medical service, transportation and cloud calculating.

China's Ministry of Science and Technology had announced that Tianhe-2 is open for users and invested thousand millions of yuan for developing applications working on the system.
