Eden Trace Viewer: A Tool to Visualize Parallel Functional Program Executions

This paper presents the Eden Trace Viewer (EdenTV), a tool which generates graphic representations of parallel program executions. The tracing tool was conceived to analyze the behavior of programs written in the parallel functional language Eden. With the high abstraction offered by parallel functional languages, tools for the analysis of the runtime behaviour are all the more important. We describe the concepts of Trace Generation, Trace Interpretation and Trace Representation in the EdenTV, giving brief technical details about its implementation. The functionality of the EdenTV is illustrated by two examples, emphasizing the utility of the EdenTV to analyze and improve the performance of parallel programs. An area of future work is to improve and optimize the tool in future versions, as well as to adapt it for other parallel functional languages.
