ParaGraph

Abstract
ParaGraph is a graphical display system for visualizing the behavior and performance of parallel programs on message-passing parallel computers. It takes as input execution trace data provided by PICL (Portable Instrumented Communication Library), developed at Oak Ridge National Laboratory and available from netlib. PICL optionally produces an execution trace during an actual run of a parallel program on a message-passing machine, and the resulting trace data can then be replayed pictorially with ParaGraph to display a dynamic, graphical depiction of the behavior of the parallel program. ParaGraph provides several distinct visual perspectives from which to view processor utilization, communication traffic, and other performance data in an attempt to gain insights that might be missed by any single view.
