Abstract
Systems and methods for communicating on a richly-connected multiprocessor computer system using a pool of buffers for dynamic association with a virtual channel. Packets are communicated in a multiprocessor computer system having a large plurality of processing nodes interconnected by a defined interconnection topology, in which a communication from a source processing node to a target processing node may pass through one or more intermediate nodes en route to the target processing node. A set of virtual channels is associated for each link in the interconnection topology. A first subset of buffers is dedicated for fixed correspondence to virtual channel identifiers, and a second subset of buffers is dedicated for dynamic allocation and assignment to virtual channels.
