Omni-Path is a high-performance communication architecture owned by Intel. This communication architecture offers low communication latency, low power consumption and a high throughput. Intel plans to develop technology based on this architecture that will serve as the on-ramp to exascale computing.
Production of Omni-Path products started in 2015 and mass delivery of these products started in the first quarter of 2016. In November 2015, adapters were launched using QSFP28 connectors with channels speeds up to 100 Gbit/s. Simultaneously, switches based on the 48-port "Prairie River" ASIC were launched.
