Frontier (supercomputer)

Frontier or OLCF-5 is an exascale supercomputer being developed at the Oak Ridge Leadership Computing Facility. It will be the United States' first exascale computer with a target computation performance of ~1.5 exaFLOPS.[2][3][4] It is being built at a cost of US$600 million. The machine began deployment in 2021[5] and is expected to reach full capability in 2022.[6]

OperatorsOak Ridge National Laboratory and U.S. Department of Energy
LocationOak Ridge Leadership Computing Facility (planned)
Power30 MW
Space2225 m2 (7,300 sq ft)
Speed>1.5 exaFLOPS (estimated speed)[1]
CostUS$600M (estimated cost)
PurposeScientific research

It is expected to use a combination of AMD Epyc CPUs and Radeon Instinct GPUs, consume 30 MW, and occupy 100 19-inch (48 cm) rack cabinets.[7][8][9]

Frontier will have coherent interconnects between CPUs and GPUs, allowing GPU memory to be accessed coherently by code running on the Epyc CPUs.[10]
