摘要： Embodiments of the invention include a method, system, and article of manufacture that provide opportunistic queuing injection strategy used for data communication between nodes of a parallel computer system. A message may be encapsulated into a set of data packets. When the packets are sent, an opportunistic injection queue may be configured to transmit them to multiple hardware injection ports. This approach allows for complete network link saturation. In a parallel system with network links in multiple dimensions, sending message packets using more than one dimension may substantially increase network throughput.
