Using Phase Analysis to Perform Accurate and Efficient Simulation

在涉及程序仿真的体系结构和系统研究中，一个至关重要的问题是如何在模拟最小数量的程序（尽可能快地收集结果）的同时，仍能获得代表程序完整执行的准确结果。本提案的目标是通过充分发展使用相位分析的技术来指导有效和准确的模拟和程序分析来解决这个问题。我们的重点是创建新的阶段分析技术，为单个程序和多线程工作负载提供非常准确和高效的仿真基础设施。这些新的相位分析技术还将纳入统计抽样，以提供具有统计保证的最小模拟点集。

Calder, BradelyCCF-0342522A crucial problem for architecture and systems research involving program simulation is how to simulate the smallest amount of the program (to gather the results as fast as possible), and still achieve accurate results representative of the complete execution of the program. The goal of this proposal is to address this problem by fully developing techniques using phase analysis to guide efficient and accurate simulation and program analysis.Our focus is to create new phase analysis techniques to provide very accurate and efficient simulation infrastructure for single program, and multi-threaded workloads. These new phase analysis techniques will also incorporate statistical sampling to provide a minimal set of simulation points with statistical guarantees.
