The TOP 500 group has been tracking the growth of the world’s most powerful computer systems since 1993. The current lists are compiled by Erich Strohmaier of NERSC/Lawrence Berkeley National Laboratory, Jack Dongarra of the University of Tennessee, Knoxville, Horst Simon of NERSC/Lawrence Berkeley National Laboratory and Martin Meuer of Pometeus GmbH.
The latest list of 500 supercomputers shows the remarkable growth of Chinese supercomputing with the number of systems in the world top 500 rising from 160 to 202 in just six months while those in the US have fallen from 169 to 143. Japan currently has 35 supercomputers, Germany 20, France 18 and the UK 15.
It is noticeable that there are very few supercomputers in Latin America, Africa, the Middle East, and South Asia. There is one in Mexico, one in South Africa, four in Saudi Arabia (three operated by Saudi Aramco), and four in India.
Currently the top five systems are:
- Sunway TaiHuLight, National Supercomputing Center, Wuxi, China
- Tianhe-2 (MilkyWay-2), National Supercomputing Center, Guangzhou, China
- Plz Daint, Swiss National Computing Centre
- Gyoukou, Japan Agency for Marine-Earth Science and Technology
- Titan, DOE/SC/Oak Ridge National Laboratory.
Chinese dominance is less evident if a list of academic supercomputers is generated. The world’s leading academic system is Oakforest-PACS in Japan, followed by Stampede 2 in Texas, TSUBAME 3.0 at the Tokyo Institute of Technology, Marconi Intel Xeon Phi at CINECA in Italy and MareNostrum at the Barcelona Supercomputing Center.
