Top500 list: a brief introduction

PDC

It ranks the world’s 500 most powerful supercomputers based on their performance as measured by the Linpack benchmark. A supercomputer that is capable of 1 exaFLOPS or higher would be called an exascale supercomputer, and, when they become available, they are expected to contribute significantly to the advancement of science and technology.
