局域网上并行计算中的通信问题

Issues of Communication in Parallel Computing on Local Area Networks

基于局域网的工作站机群（NOW），以其巨大的计算潜力、良好的性能价格比、可扩展性又灵活的体系结构而受到人们的重视。要建立有良好并行性能的NOW通用系统，必须解决许多问题，如工作站间通信开销大的问题。负载平衡问题、异构、容错等问题。文章较详细地讨论了在实现NOW系统存在的一些通信问题，并分析了国内外对此所做的一些工作。

NOW on LAN has been mentioned for it's hign compuhng potential,good performance /cost and feasiblearchitectUre.In ortler tO establish a general NOW system with excellent Paneling Performance,some problems suchas communication overhead betWeen workstations,load balanc lug, heterogeneity,fault toleranc e and s c heduling must besolved.This paper discusses several problems of communication in NOW system and analysis some related works.
