\chapter{Introduction}
With the ever increasing dissemination of multi-core architectures,
parallel and/or distributed applications are becoming the norm, so
as to use computer resources as efficiently as possible. Trace
collection and visualization is useful for developers willing to
debug and monitor the performance of their parallel applications.
Yet, most existing trace visualization tools are proprietary or
cannot handle large trace files.
\ViTE is a powerful, portable and open-source profiling tool which
visualizes the traces produced by parallel applications. Thanks to
its scalable design, \ViTE efficiently helps programmers to analyze
the performance of potentially large applications running on many
nodes, cores and communicating processes.
\ViTE allows one to visualize traces written in the \paje open format
(see \\ \url{http://www-id.imag.fr/Logiciels/paje/}) and the OTF. Its features include
the ability to export views in the SVG format, so as to integrate
them easily into reports, and the production of statistics.
The aim of \ViTE is to have a free and open software able to display different traces format with a user-friendly interface. That is why it is under Cecill-A licence (you can see the content on chapter \ref{Licence}).
More information are available on the official website of\\ \ViTE~:
\url{http://vite.gforge.inria.fr/},\\ or on the forge itself~:
\url{http://gforge.inria.fr/projects/vite/}.
This document is a start guide for understanding how to use \ViTE.
The figures \ref{exempleViTE1} and \ref{exempleViTE2} are examples of a trace you can watch with \ViTE.
