摘要
并行计算模型是设计和分析并行算法的基础和关键,在实现高性能网络计算中起重要作用.LogP是一个面向高性能并行计算的现实模型.它可以用来作为快速的、可移植的并行算法的基础.这个模型基于四个参数,即L、o、g、P.这些参数反映了高性能网络并行计算的计算带宽、通信带宽、通信延迟、以及传输和计算的结合效率.
The model of parallel competition is the basis and key for design and analysis of parallel algorithms. It plays role in high performance network parallel computation. LogP is a realistic model towards parallel computation. It is intended to serve as a basis for developing fast, portable parallel algorithms. This Model is based on four parameters. which are called L、o、g、P . These parameters specify the computing bandwidth, the communication bandwidth, the communication delay, and the efficiency of coupling communication and computation in a high performance network parallel computation system.
