Top 500 is a ranking of the world’s most powerful computer systems and is published twice a year. The current authors are Erich Strohmeier and Horst Simon of NERSC/ Lawrence Berkeley National Laboratory, Jack Dongarra of the University of Tennessee, Knoxville, and Martin Meuer of Prometeus GmBH.
In previous years the upper levels of the ranking have been dominated by the USA and China. The latest edition just published shows, however, that the most powerful computer system in the world now is Fugaku, recently installed at the RIKEN Center for Computational Science (R-CCS) in Kobe, Japan.
The top 500 supercomputer list shows that China leads in system share with 226 systems, followed by the US with 113, Japan 29, France 19 and Germany 16. There are only two each in India and Russia and none anywhere in Africa.
This represents a slight decline for China and the US which had 228 and 117 systems respectively in the top 500 in November of last year.
The top five systems are:
- Supercomputer Fugaku. RIKEN Center for Computational Science
- DOE/SC/ Oak Ridge National Laboratory, USA
- DOE/NNSA/LLNL, USA
- Sunway TaihuLight. National Supercomputing Center, Wuxi, China
- Tianhe-2A. National Super Computer Center, Guangzhou, China.
It is possible for users to create sublists. The top five academic systems are:
- Frontera. Texas Advanced Computing Center/University of Texas, USA
- Marconi-100. CINECA, Italy
- SuperMUC-NG. Leibniz Rechenzentrum, Germany
- Oakforest-PACS. Fujitsu Joint Center for Advanced high Performance Computing, Japan
- Stampede2. Texas Advanced Computing Center, USA.
