Analyzing Overheads and Scalability Characteristics of OpenMP Applications

Tags:
scalability

Overview Analyzing the scalability behavior and the overheads of Open-MP 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. This paper presents a methodology which defines four overhead categories that can quantify exactly and describe a tool that implements this methodology. This paper evaluates the tool on the OpenMP version of the NAS parallel benchmarks.
