摘要

在并行计算中，为了达到创建最高效并行计算的目标，评估加速差的原因是一项重要的开发活动。在我们对不规则并行计算，特别是图算法的研究中，我们有特定的测量需求，而缺乏相应的工具。我们创建了PGOMP，这是一个用于Gnu OpenMP实现的小型基于库的分析工具，并在这里展示了它在发现图形计算加速差的一些原因中的用途。

Binary instrumentation support for measuring performance in OpenMP programs

In parallel computations, evaluating the causes of poor speedup is an important development activity to reach the goal of creating the most efficient parallel computation possible. In our research on irregular parallel computations, especially graph algorithms, we had specific measurement needs for which a dearth of tools could be found. We created PGOMP, a small library-based profiling tool for the Gnu OpenMP implementation, and show its use here in discovering some of the causes of poor speedup in graph computations.
