Visualization, Execution trace

ViTE is a trace explorer. It is a tool made to visualize execution traces of large parallel programs. It supports Pajé, a trace format created by Inria Grenoble, and OTF and OTF2 formats, developed by the University of Dresden and allows the programmer a simpler way to analyse, debug and/or profile large parallel applications. It is an open source software licenced under CeCILL-A.

The ViTE software is available at http://vite.gforge.inria.fr and has been developed in collaboration with the Inria Bordeaux - Sud-Ouest SED team, Telecom SudParis and Inria Grenoble.

In the same context we also contribute to the EZtrace and GTG libraries in collaboration with F. Trahay from Telecom SudParis. EZTrace (http://eztrace.gforge.inria.fr ) is a tool that aims at generating automatically execution trace from HPC programs. It generates execution trace files thanks to the GTG library (http://gtg.gforge.inria.fr ) that can be later interpreted by visualization tools such as ViTE .
