| 摘 要： | 分析了几种可扩展性能评价模型存在的问题，针对实际评价与测试的需要，提出了一种基于等平均负载的数值并行计算可扩展性评价模型．该评价模型对可扩展性能加速比和可扩展性进行了重新定义，给出了使用该模型的进行可扩展加速比和可扩展性测试的方法，结合曲线拟合或并行计算时间模型可以预测并行系统的可扩展性，对NPB BT，SP和矩阵乘法进行了可扩展性预测．

| Abstract: | In this paper, the existing problems of the current scalability models are analyzed, and aiming at the requirements of the practical evaluations and tests, a practical scalability metric based on iso-average-computation-load is proposed to provide a quantitative measurement of the scalability. In this metric, the definitions of scalable speedup and scalability are different from the current metrics. By using this metric, a practical method can be obtained to test scalable speedup and scalability, and combined with curve fitting or parallel computing time model, the scalabilities of parallel systems can be predicted. |
