Compiler-Based Tools for Analyzing Parallel Programs

In this paper, we present several tools for analyzing parallel programs. The tools are built on top of a compiler infrastructure, which provides advanced capabilities for symbolic program analysis and manipulation. The tools can display characteristics of a program and relate this information to data gathered from instrumented program runs and other performance analysis tools. They also support an interactive compilation scenario, giving the user feedback on how the compilation process performed and how to improve it. We will present case studies demonstrating the tool use. These include the characterization of an industrial application and the study of new compiler techniques and portable parallel languages.
