Abstract:

Jumpshot-3 is the 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, like AIX's UTE slogmerge or MPICH's MPE profiling library. Basically, Jumpshot-3 is a GUI to display rectangles which represent the various MPI and user defined states and arrows which represent messages exchanged between those states. This article serves to illustrate 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.
