Abstract : |
ParaGraph is a graphical display system for visualizing the behavior and performance of parallel programs on message-passing multicomputer architectures. The visual animation is based on execution trace information monitored during an actual run of a parallel program on a message-passing parallel computer. The resulting trace data are replayed pictorially to provide a dynamic depiction of the behavior of the parallel program, as well as graphical summaries of its overall performance. Many different visual perspectives are provided from which to view the same performance data, in an attempt to gain insights that might be missed by any single view. We describe this visualization tool, outline the motivation and philosophy behind its design, and provide details on how to use it. This user guide is adapted from a technical report [6], which also appears in a modified form in [7]. The principal modifications to produce this manual were the omission of, |
