INTEL OMNI-PATH SWITCHES

IMPROVE THE PERFORMANCE OF YOUR FUTURE HPC WORKLOADS 

Intel® Omni-Path Fabric Edge switches are part of an end-to-end product family for HPC fabrics that delivers high performance with breakthrough value.
Intel OPA is being designed specifically to address HPC needs to scale cost-effectively from entry level HPC clusters to larger clusters with 10,000 nodes or more at a competitive price with today’s fabrics. 
Also, they are consistent and compatible with existing Intel True Scale Fabric and InfiniBand* APIs by working through the open source OpenFabrics Alliance (OFA) software stack on leading Linux* distribution releases. Intel True Scale Fabric customers will be able to migrate to Intel OPA through an upgrade program.   


KEY FEATURES



HIGHLIGHTS

ADAPTIVE ROUTING to monitor the performance of the possible paths between fabric end-points and selects the least congested path to rebalance the packet load

DISPERSIVE ROUTING to disperse traffic flows for redundancy, performance, and load balancing.

TRAFFIC FLOW OPTIMIZATION to reduce the variation in latency seen through the network by high priority traffic in the presence of lower priority traffic. 

PACKET INTEGRITY PROTECTION to allow for rapid and transparent recovery of transmission errors between a sender and a receiver on an Intel Omni-Path Architecture link

DYNAMIC LANE SCALING to allow an operation to continue even if one or more lanes of a 4x link fail, saving the need to restart or go to a previous checkpoint to keep the application running
