NAME


viva - Interactive and dynamic graph visualization of a Paje trace file

SYNOPSIS


viva [OPTIONS] <TRACEFILE> <VIVA_CONFIGURATION>

DESCRIPTION


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).

OPTIONS


viva accepts the following options:

-?, --help
Show all the available options.

--usage
Give a short usage message.

INPUT DESCRIPTION


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.

Viva Configuration File
Forthcoming. See the examples directory in the meanwhile.

OUTPUT DESCRIPTION


Forthcoming.
