摘要

Interconnection networks with nearly distance independent communication latency are a key feature of recent architectures. However, shared resources such as network channels can become bottlenecks that degrade performance and limit workload scalability. In this paper, the problem of network contention in medium scale multi-computers is addressed. A queueing network model that predicts application speedup on the Paragon is presented. The model has been experimentally validated under the SUNMOS operating system. The experimental and modeling results are in good agreement and suggest ways to avoid internal network contention of communication intensive applications on the Paragon.
