Virtual-channel flow control

摘要: Network throughput can be increased by dividing the buffer storage associated with each network channel into several virtual channels. Each physical is small queues, channels, rather than a single deep queue. The channels one are allocated independently but compete other for bandwidth. Virtual decouple resources from transmission resources. This decoupling allows active messages to pass blocked using bandwidth that would otherwise left idle. paper studies performance of networks both analysis and simulation. These show increase throughput, factor four 10-stage networks, reduce dependence on depth network. >
