context_page_description: Summit or OLCF-4 is a supercomputer developed by IBM for use at Oak Ridge National Laboratory, capable of 200 petaFLOPS, making it the fastest supercomputer in the world from November 2018 to June 2020. Its current LINPACK benchmark is clocked at 148.6 petaFLOPS. As of November 2019, the supercomputer is also the 5th most energy efficient in the world with a measured power efficiency of 14.668 gigaFLOPS/watt. Summit is the first supercomputer to reach exaflop speed, achieving 1.88 exaflops during a genomic analysis and is expected to reach 3.3 exaflops using mixed precision calculations.
