Anthony Chan, William Gropp, Ewing Lusk



Jumpshot-3 is a display program for trace data in scalable log format, [SLOG-1], which is designed to store a large number of drawable objects[SLOG-2] generated from the backend of a parallel program, for example AIX's UTE slogmerge or MPICH's MPE profiling library. Basically, Jumpshot-3 is a GUI to display rectangles that represent the various MPI and user-defined states and arrows indicating messages exchanged between those states. This article illustrates the basic functionalities of Jumpshot-3 through a step-by-step guide of how one would usually use Jumpshot-3 to view a big logfile.
