SYSTEM OF EXPRESS CHANNELS IN AN INTERCONNECTION NETWORK THAT AUTOMATICALLY BYPASSES LOCAL CHANNEL ADDRESSABLE NODES

An interconnection network is embellished with express channels that serve as parallel alternative paths to local channels between non-local nodes of the network. The use of the express channels increases throughput and diminishes latency experienced by the network. A single express channel may be used for a given sequence of nodes or alternatively multiple express channels may be utilized. Furthermore, express channels may be oriented in more than one dimension. Interchanges act as routing interfaces between the express channels and the conventional channels. The interchanges may be used as interfaces that adjust the wire density signalling level and speed at the boundaries of modules.
