Frontier (supercomputer)

Hewlett Packard Enterprise Frontier, or OLCF-5, is the world's first exascale supercomputer. It is hosted at the Oak Ridge Leadership Computing Facility (OLCF) in Tennessee, United States, and became operational in 2022. As of November 2024, Frontier is the third fastest supercomputer in the world. It is based on the Cray EX and is the successor to Summit (OLCF-4). Frontier achieved an Rmax of 1.102 exaFLOPS, which is 1.102 quintillion floating-point operations per second, using AMD CPUs and GPUs. Measured at 62.86 gigaflops/watt, the smaller Frontier TDS (test and development system) topped the Green500 list for most efficient supercomputer until it was dethroned in efficiency by the Flatiron Institute's Henri supercomputer in November 2022. Frontier was superseded as the fastest supercomputer in the world by El Capitan in November 2024.
