Omni-Path Architecture

Intel's 100 Gb/s fabric, discontinued as an Intel product in 2019 and carried forward independently by Cornelis Networks from 2020. Edges from before that date record Intel as the supplier at build.

Why this part

Intel bought QLogic's InfiniBand business and Cray's interconnect team and merged them into Omni-Path, intending to own the fabric as well as the processor. It was competitive, several large machines bought it, and Intel discontinued development in 2019, leaving SuperMUC-NG, Stampede2, TSUBAME3.0, ABCI and MareNostrum 4 on an abandoned network. The assets went to Cornelis Networks, which still ships it. A fabric is a longer commitment than a processor, because replacing one means recabling the building.
