系统度量指标的研究一直是并行系统和应用设计的重要问题。本文首先通过对国内外并行计算系统度量指标的分析，将当前并行计算系统度量指标分为单一的计算性能度量指标和多要素综合的高效能度量指标两种。其次，总结了这些度量指标的研究现状，并指出这些度量指标研究中存在的一些问题以及需要考虑的难点。由于并行计算系统正在逐渐从“高性能”走向“高效能”，本文主要考虑当前大规模并行计算系统的可靠性和能耗要素对系统的影响，从系统可扩展角度建立了可靠并行加速比和能耗并行加速比模型，并进一步扩展为度量并行计算系统效能的综合指标模型。最后指出了未来并行计算系统度量的研究方向。

The research of metrics for evaluating parallel computing systems is important to parallel systems and application design. First,based on an analysis of the current metric models for parallel computing systems,this paper classifies these model into two categories including the single computing performance model and the synthetically multiple factors productivity model. The work which has been done in the field is reviewed. Then,the various metrics are described. Something that is missing in the current research and the factors which should be considered in building the metric model are pointed out. Since the measure index for the performance of the systems demands a shift from “high performance” to “high productivity”,the paper takes the reliability and energy consumption into account,builds the reliability parallel speedup and energy parallel speedup model in view of scalability,and further proposes a metric model for evaluating the productivity of parallel computing systems. Finally,the direction of further research is proposed.
