Abstract :
ParaGraph, a software tool that provides a detailed, dynamic, graphical animation of the behavior of message-passing parallel programs and graphical summaries of their performance, is presented. ParaGraph animates trace information from actual runs to depict behavior and obtain the performance summaries. It provides twenty-five perspectives on the same data, lending insight that might otherwise be missed. ParaGraph´s features are described, its use is explained, its software design is briefly discussed, and its displays are examined in some detail. Future work on ParaGraph is indicated.<>
