Resilient Interconnect Network In Large Scale Computing

Abstract

The technology is generally for providing resilience to interconnect networks in large scale computing. Processing nodes of the network are arranged in reconfigurable pods that can contain large numbers of processing nodes. Processing nodes are grouped into building blocks of the pod, each building block may be contained within a physical computing rack. Processing nodes are interconnected via interconnect pathways that connect processing nodes to network switches. A building block's processing nodes communicate to network switches through regular communication pathways via the interconnect network. Additionally, a protection communication path is provided between a building block and the network. If a regular communication path is affected by a failure of a switch or interconnect link, the protection pathway is used to route the traffic affected by the failure without impacting the computing network. An electrical circuit switch is provided at the building block level to route data to the protection pathway.
