According to the list released on, Japan's "K," built by Fujitsu, can make 8.2 quadrillion calculations each second and is the new number one supercomputer in the world.

Tianhe-1A supercomputer in China's National Supercomputing Center in Tianjin, with a performance at 2.6 quadrillion calculations per second currently ranks second on the list.

Including Tianhe-1A and Nebulae, the world's fourth fastest supercomputer, China has 62 supercomputing systems on the top 500 list. Both the numbers and accumulated peak performance of China's supercomputers have exceeded that of traditional leading countries in supercomputer development, including Germany, Japan and France. The United States, with 256 supercomputers on the list, has a good lead in this field.

China had 41 supercomputers listed on the top 500 list released in last November. The increase in the last half year showed China's increased portion of global fastest supercomputers. releases the top 500 supercomputer lists twice a year. All the top 10 supercomputers on the latest list — five from the United States, two from China, two from Japan and 1 from France — can make more than 1 quadrillion calculations per second.
