Cornelis Omni-Path Express Edge Switches

Cornelis Omni-Path Express Accelerated Host Fabric Adapters are designed to provide a perfect semantic match between the requirements of real-world HPC applications and the scale-out fabric, maximizing performance at scale.

Cornelis Omni-Path Express adapters come in PCI low profile and Open Compute Project (OCP) 3.0 form factors and deliver scalable bandwidth in increments of 100 Gbps, 250 million MPI messages per second, and sub-microsecond MPI latency.

Other advanced performance features include dispersive routing, congestion control, a unique sub-link layer architecture that enables Packet Integrity Protection (zero latency protection against bit transmission errors), and Virtual Fabrics support.

  • Cornelis Networks provides the industry’s leading edge switch.

    Omni-Path Express Edge Switches costeffectively deliver high bandwidth and use advanced technologies to meet the key challenges to application performance, maximizing cluster scalability and message rate while minimizing.

    Cornelis Omni-Path Express scale-out interconnect

    Cornelis Omni-Path Express scale-out interconnect Unprecedented demands on the scale-out interconnect are being driven by advances in artificial intelligence, high performance data analytics, and traditional modeling and simulation environments, coupled with extremely capable processing and storage infrastructures.

    Cornelis Omni-Path Express is the next generation of high performance fabrics, a proven hardware foundation combined with the OpenFabrics Interfaces (OFI) software framework, that delivers the industry’s lowest latency, highest message rate, and best collectives performance, all at the industry’s lowest CPU utilization

    Accelerated application performance at scale.

    Cornelis Omni-Path Express Edge Switches provide forty-eight 100 Gbps ports, delivering full bidirectional bandwidth per port.

    Cornelis Omni-Path Express Edge Switches are very versatile, as the only switch in small clusters, the first tier switch in larger clusters, and the network core in intermediate clusters.

    The Omni-Path Express Edge Switches ensure optimal application performance by delivering key features for efficiency, including dynamic adaptive routing and congestion control.

    These features are complemented by a unique sub-link layer architecture that enables Packet Integrity Protection (zero latency protection against bit transmission errors) and Traffic Flow Optimization (pausing the transmission of a lower priority packet in favor of a higher priority packet).

    These features, together with advanced Virtual Fabrics support, provide the unique interconnect capabilities to deliver industry leading application performance and manageability at scale.
