Intel's Omni-Path Architecture
The Next-Generation Fabric for HPC
Intel's Omni-Path Architecture (OPA) is the latest generation of fiber interconnect architecture and the successor to the Intel True Scale Fabric.
Intel OPA delivers the performance for tomorrow's high performance computing (HPC) workloads and the ability to scale to tens of thousands of nodes—and eventually more—at a price competitive with today’s fabrics. With increases in total bandwidfth from 40GB/s to 100GB/s and added performance features designed specifically for HPC, Intel OPA is the ideal fabric used to support clusters of all sizes with optimization for HPC applications at both the host and fabric levels for benefits that are not possible with standard Infiniband-based designs. The entire Intel OPA 100 Series is an end-to-end solution of PCIe adapters, silicon, switches, cables, and management software.
Intel OPA Software Components
The Intel OPA host software stack and the Intel® Fabric Suite are the components of Intel® OPA software. Unlike Mellanox software, Intel OPA software including Host software and Fabric Manager are offered for free!
Intel will Open Source all Host Fabric Components such as the Driver, PSM, Libfabric providers, Fabric Manager, FastFabric tools, HFI diags, FM GUI, OFA enhancements: patches, plugins, etc. In addition, host components will be upstreamed to be delivered as a part of the Operating system.
