Parallel Visualization - (Master's Thesis, French Report)

Hi-performance, parallel and distributed visualization on hi-speed networks

Increasing industrial needs for precision and quality in scientific simulations lead to the manipulation of extremely large volumes of data ranging from millions to hundreds of millions of elements. The visualization of such data is very challenging and requires intensive parallelization at all levels, because of the limited memory and computing power available.

This work adresses both limitations by taking advantage of new high-speed network technologies provided by the CARRIOCAS project that enable the use of stream-based approaches for high-performance parallel and distributed rendering.

This document describes two essential aspects of our work: On one hand, we developed an image streaming solution based on the VideoLan Client by the Ecole Centrale Paris, that is dedicated to distant visualization by thin clients. On the other hand, we implemented a hybrid algorithm that enables both resolution and complexity scaling while maintaining application-level transparency thanks to OpenGL interception techniques.

We then estimate the performance of these tools against both commercial and free software.
