.SH DESCRIPTION
\fBViTE\fP is a visual trace explorer. It is a useful tool for profiling and debugging parallel programs (multi\(hyprocess or multi\(hycore).
.br
\fBViTE\fP reads program execution trace data from file (currently in Pajé trace format) and display it in a graphical interface. Program execution data could be a \fBstate\fP (drawn as a colored rectangle \- color depends of the kind of state), an \fBevent\fP (drawn as a green disc) or a \fBcommunication\fP between two processes (drawn as a white arrow).
.PP
Unlike \fBvite\fP, \fBvite\-vbo\fP uses OpenGL's feature VBO (Vertex Buffer Object), which can improve performance of rendering, but can require more GPU memory.
.SH OPTIONS
\fBViTE\fP accepts the following options:
.TP 8
\fB\-h\fP
Display help.
.TP 8
\fB\-f\fP \fIfile_path\fP
Open the \fIfile_path\fP file.
.TP 8
\fB\-a\fP \fIfile_path\fP
Open the \fIfile_path\fP file and display it entirely.
.TP 8
\fB\-e\fP \fIexport_path\fP
Export the opened trace file (with \fB\-f\fP or \fB\-a\fP option) to the \fIexport_path\fP file in SVG format.
.TP 8
\fB\-t\fP [\fItime_init\fP]:[\fItime_end\fP]
Just parse trace from \fItime_init\fP to \fItime_end\fP.
.br
If \fItime_init\fP is missed, trace will be parsed from the minimum time to \fItime_end\fP.
.br
If \fItime_end\fP is missed, trace will be parsed from \fItime_init\fP to the maximum time.
.SH AUTHORS
\fBViTE\fP was created by a group of french engineering school students for the INRIA research center.
.SH "REPORTING BUGS"
Report bugs to ViTE developers <vite\-issues@inria.fr>.
