For visualization, I recommend you to take a look at Pajé: http://www-id.imag.fr/Logiciels/paje/ It is free software (LGPL): http://forge.objectweb.org/projects/paje/ I have seen it used for the visualization of events (for the analysis of deadlocks, etc.) in a heavily multi-threaded Java application. A custom Linux module collected all the events, and Pajé was used "post-mortem" for visualization of the events. It seems very similar to what you want to do, except that you would use LTTng instead of a custom module to record events. And there are nice publications about Pajé for your student to cite. ;-) -- Romain LENGLET _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
