文摘仿真点(simulation point,SimPoint)作为一种代表性采样技术被广泛应用于处理器硅前性能评估中。SimPoint为每个待评估的程序根据贝叶斯信息准则确定仿真点数目。然而,标准测试集内不同程序有着不同的行为复杂程度,需要不同数目的仿真点来准确刻画其程序行为。SimPoint无法识别出不同程序间的复杂度差异,无法做到在总仿真点数目一定的情况下,将更多的仿真点分配给行为复杂的程序以降低这些程序的性能评估误差,将更少的仿真点分配给行为简单的程序而不损失这些程序的性能评估精度。由于没有在测试集内合理地进行仿真点分配,SimPoint虽然可以给出比较准确的平均性能评估误差,但是某些行为复杂的测试子项的性能评估误差依然较大。针对这一问题,本文优化了SimPoint的仿真点局部分配方式,提出了一种全局贪心分配方法———贪心点(greedy point,GreedyPoint)方法。该方法将仿真点的分配问题抽象为含约束的优化问题,使用微架构无关特征计算表征误差,通过全局贪心算法来求解该优化问题。实验数据表明,在相同仿真开销下,与SimPoint相比,GreedyPoint可以将SPEC CPU 2017测试套件的平均性能评估误差由3.23%降低到2.08%,最大性能评估误差由21.22%大幅降低至7.01%。
