Summit or OLCF-4 is a supercomputer developed by IBM for use at Oak Ridge Leadership Computing Facility (OLCF), a facility at the Oak Ridge National Laboratory, United States of America. As of June 2024, it is the 9th fastest supercomputer in the world on the TOP500 list. It held the number 1 position on this list from November 2018 to June 2020.[5][6] Its current[when?] LINPACK benchmark is clocked at 148.6 petaFLOPS.[7]

As of November 2019, the supercomputer had ranked as the 5th most energy efficient in the world with a measured power efficiency of 14.668 gigaFLOPS/watt.[8] Summit was the first supercomputer to reach exaflop (a quintillion operations per second) speed, on a non-standard metric, achieving 1.88 exaflops during a genomic analysis and is expected to reach 3.3 exaflops using mixed-precision calculations.[9]
