The TOP500 list is a ranking of the world’s most powerful supercomputers. The ranking includes those systems in general use for high end applications and is based on the LINPACK benchmark. The latest edition suggests that there may be a renaissance in American supercomputing. The top place has been held by the Summit system at the Oak Ridge National Laboratory in Tennessee since June 2018 and second place since November 2019 by Sierra at the Lawrence National Laboratory in California. The ranking was compiled by Erich Strohmaier and Horst Simon of NERSC/Lawrence Berkeley National Laboratory, Jack Dongarra of the University of Tennessee, Knoxville, and Hans Meuer of the University of Mannheim, Germany.

In recent years the trend has been for the number of US systems to decline and Chinese systems to increase.  Over the last seven months the number of US systems in the top 500 has increased from 109 to 116 compared to a decrease for Chinese systems from 227 to 219. The number of Eastern European systems has also fallen. There were four Polish and three Russian supercomputers in November. Now there are one Polish and two Russian.

Europe Japan and the US performs well for academic systems. The first place in this category goes to Frontera at the Texas Advanced Computing Center at the University of Texas followed by the SuperMUC-NG at Leibniz Rechenzentrum in Germany. The top twenty in this category consists of six Japanese, five US, three Germany, two French and one Italian, Swedish, Saudi and Spanish.
