TOP 500 is a list of the world’s 500 most powerful computer systems. It has been published twice a year since 1993. Systems are ranked by their performance on the LINPACK Benchmark. However, any system created specifically to compete in the rankings is not considered.

The top supercomputer system is Summit at Oak Ridge National Laboratory (ORNL) followed by Sierra at Lawrence Livermore National Laboratory (LLNL), both in the United States. There are another three US Department of Energy supercomputers in the top ten. Third place goes to the Sunway TaihuLight system, at the National Supercomputing Center in Wuxi. Tianhe-2A (Milky Way-2A), at the National Supercomputer Center in Guangzho, China is fourth and Piz Daint, at the Swiss National Supercomputing Centre (CSCS) in Lugano is fifth.

The compilers of the list are 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 Prometeus (and, from 1993 until his death in 2014, Hans Meuer of the University of Mannheim, Germany).

In the current ranking China accounts for 227 of the systems in the top five hundred, up from 206 six months ago while the USA has 109, down from 124 in June. Japan has 31, the UK 20, and France 18.

The most powerful academic supercomputer is SuperMUC-NG at Leibnitz Rechenzentrum in Germany.
