System and method for establishing sufficient virtual channel performance in a parallel computing network

摘要

A method for interconnecting multiple computational devices in a parallel computing network including a plurality of serially associated pairs of nodes, wherein each of the pairs of nodes is interconnected via at least one physical communication channel. A sufficient virtual channel rate required to provide a predetermined amount of Amdahl scaling is first determined. The maximum number of virtual channels, each having a transmission rate at least equal to the sufficient virtual channel rate, that can be implemented over each physical communication channel is then determined. The physical communication channel between each of the nodes is then subdivided into the determined maximum number of virtual channels.
