Frontier, or OLCF-5, is the world's first exascale supercomputer, hosted at the Oak Ridge Leadership Computing Facility (OLCF) in Tennessee, United States. It is the successor to Summit (OLCF-4). As of June 2022[update] Frontier is the world's fastest supercomputer.[2][3][4][5] Frontier has been measured to achieve an Rmax of 1.102 exaFLOPS.[6]
| Operators | Oak Ridge National Laboratory and U.S. Department of Energy |
|---|---|
| Location | Oak Ridge Leadership Computing Facility |
| Power | 21 MW |
| Space | 680 m2 (7,300 sq ft) |
| Speed | 1.102 exaFLOPS (Rmax) / 1.685 exaFLOPS (Rpeak)[1] |
| Cost | US$600M (estimated cost) |
| Purpose | Scientific research |
Frontier uses a combination of AMD Epyc 7A53s 64 core CPUs and Radeon Instinct MI250X GPUs, and occupies 74 19-inch (48 cm) rack cabinets.[7] Frontier has coherent interconnects between CPUs and GPUs, allowing GPU memory to be accessed coherently by code running on the Epyc CPUs.[8]
The machine was built at a cost of US$600 million. It began deployment in 2021[9] and reached full capability in 2022.[10] It has been clocked at 1.1 exaflops Rmax as of May 2022 making it the world's fastest supercomputer as measured in the June 2022 edition of the TOP500 list, replacing Fugaku.[11][12]
The supercomputer also tops the related Green500 list for most efficient supercomputer, measured at 62.68 gigaflops/Watt.[6] Frontier consumes 21 MW (compared to its predecessor Summit's 13 MW); it has been estimated that the successor to Frontier, or Aurora, will consume around 60MW.[citation needed]
