Abstract

Analyzing the scalability behavior and the overheads of OpenMP applications is an important step in the development process of scientific software. Unfortunately, few tools are available that allow an exact quantification of OpenMP related overheads and scalability characteristics. We present a methodology in which we define four overhead categories that we can quantify exactly and describe a tool that implements this methodology. We evaluate our tool on the OpenMP version of the NAS parallel benchmarks.
