This training presents advanced visualization techniques using the open source software Paraview. The objective of the training is to give good practices for visualizing results of large scale simulations on advanced parallel computers. 

We present parallel usage (client-server and parallel IO),  the IO types best adapted to high performance visualization, as well as the remote connection to simulation codes enabling in situ visualization. 

These techniques will be demonstrated on the stereoscopic visualization wall at Maison de la Simulation  (www.maisondelasimulation.fr/Visualisation.php).

The presented tools will be illustrated during hands-on sessions.

Course outline
