Summit or OLCF-4 is a supercomputer developed by IBM for use at Oak Ridge National Laboratory, which as of June 8, 2018 is the fastest supercomputer in the world, capable of 200 petaflops. Its current LINPACK benchmark is clocked at 122.3 petaflops. As of June 2018, the supercomputer is also the 5th most energy efficient in the world with a measured power efficiency of 13.889 GFlops/watts. Summit is the first supercomputer to reach exascale speed, achieving 1.88 exaops during a genomic analysis and is expected to reach 3.3 exaops using mixed precision calculations.
