viva(1) Interactive and dynamic graph visualization of a Paje trace file




The viva(1) command displays a dynamic, interactive and hierarchical graph visualization of a Paje trace file. Dynamic because it uses a scalable barnes-hut graph positioning algorithm provided by libtupi, bundled within viva. Interactive because the visualizaton allows the user to interact with the graph, either by moving nodes positions or changing the time frame considered to draw its temporal data. And hierarchical because the graph exposes the internal organization of the Paje trace file. Viva is a particularly useful program to correlate the behavior of parallel and distributed applications with the underlying network topology, by mapping this behavior to visual elements of the graph representation (size of nodes, edges, and so on). A good analysis using viva depends directly to the configuration file provided as second parameter (see INPUT DESCRIPTION section for details).


viva accepts the following options:

Give a short usage message.


The viva(1) command expects two parameters: the first one is a trace file that follows the Paje file format (as described in the PDF document listed in the RESOURCES section of this page). The second is a viva configuration file with a syntax similar to property lists, a simple textual format. This configuration file is used to map the contents of the Paje trace file to the graph visualizaton construction. If these two obligatory parameters are not provided, viva(1) stops with a usage message.
