Abstract

Abstract: Scalability has become an important concept in parallel computer system and parallel algorithms.The characteristics of four existing scalability metrics are analysed for parallel computing system，i.e.，the iso-efficiency metrics，iso-speed metrics，average latency metrics and iso-ratio-of-parallel calculation-overhead metrics.A new scalability metric which reflects the scalability of parallel computer system more directly and precisely is proposed.This paper presents some experiments.The results show that this metric can estimate preferably the scalability of parallel computing systems.

Key words: architecture, parallel computing, performance, scalability

摘要：

可扩展性是设计并行计算系统和并行算法所要考虑的一个重要性能指标。分析了等效率、等速度、平均延迟和等并行计算开销比几种并行系统可扩展性模型的特征，提出了一种新的更有效的可扩展性度量标准。通过实验结果分析，该模型能很好地评测并行计算系统的可扩展性。
