Jumpshot
Section contributed by IICT-BAS
SLOG-2 is Argonne Lab's MPI logging package that includes a visualization tool, Jumpshot-4, that allows you to 'see' MPI events in your program and how they relate to time and events in other processes. Jumpshot works by reading a log file that was generated on a run of your MPI program after it has been properly instrumented. Jumpshot-4 allows seamless scrolling from the beginning to the end of the logfile at any zoom level. The main visual component in the SLOG-2 visualization program, Jumpshot-4, is the timeline canvas, which is zoomable and scrollable in both the horizontal and vertical axes. The timeline canvas can be thought of as a timeline vs. time coordinate system. Each point on the canvas is identified by two numbers: a timestamp and a timeline ID. The graphical objects contained in the SLOG-2 file are drawn on the canvas.
