摘要

大多数程序都是重复的,在不同的执行时间可以看到类似的行为。提出的算法自动地将程序执行的相似部分分组为阶段,其中每个阶段的间隔具有相同的行为和相似的资源需求。这些先前的技术专注于固定长度的间隔(例如1亿条指令)来寻找相位行为。固定长度的间隔可能使程序的周期相位行为难以发现,因为固定的间隔长度可能与程序的实际相位行为的周期不同步。此外,固定的间隔长度只能表达一个层次的相位行为。在本文中,我们图解地说明了在程序中存在一个相位行为层次,并激发了对可变长度间隔的需求。我们描述了应用于SimPoint以支持可变长度间隔的更改。最后,我们提供了一个关于使用可变长度间隔来指导SimPoint的初步研究

Motivation for Variable Length Intervals and Hierarchical Phase Behavior
Most programs are repetitive, where similar behavior can be seen at different execution times. Proposed algorithms automatically group similar portions of a program's execution into phases, where the intervals in each phase have homogeneous behavior and similar resource requirements. These prior techniques focus on fixed length intervals (such as a hundred million instructions) to find phase behavior. Fixed length intervals can make a program's periodic phase behavior difficult to find, because the fixed interval length can be out of sync with the period of the program's actual phase behavior. In addition, a fixed interval length can only express one level of phase behavior. In this paper, we graphically show that there exists a hierarchy of phase behavior in programs and motivate the need for variable length intervals. We describe the changes applied to SimPoint to support variable length intervals. We finally conclude by providing an initial study into using variable length intervals to guide SimPoint
