Demonstrating real-time tile-based visualization at Supercomputing 2018

CEA is participating in the International Conference for High Performance Computing to be held 11-16 November 2018 in Dallas, Texas. Among other things, CEA will present a demonstration of tile-based visualization for Big Data in neurobiology and astrochemistry.

Published on 24 October 2018

The Maison de la Simulation joint research center (CEA-CNRS-UVSQ-Université de Paris-Sud) in Paris-Saclay is developing a mosaic visualization tool called TiledViz to simultaneously explore dozens of 3D images from simulations or real data collections.

Applied to brain imaging, such a tool makes it possible to establish a dictionary of all the patterns frequently observed in the population and their variability. It also makes it possible to define abnormal criteria for the patterns, for example in order to establish early diagnoses of certain pathologies.

In a completely different field, TiledViz makes it possible to analyze a set of molecular dynamics trajectories linked to astrochemical reactions. The aim is to research and understand the possible synthesis pathways for the formation of complex organic molecules in space.

On a giant screen using 3D visualization, TiledViz software presents side by side the output of each visualization tool. Scientists are then able to analyze several simulations at the same time, according to various parameters, or to compare similar results visually. In real time, the 3D images can easily be manipulated, classified, qualified and annotated using a touch table. Since the software is generic, it can manage data sets from a wide variety of sources to adapt to the needs of each scientific community.

TiledViz will be demonstrated at the Supercomputing Conference in Dallas on 11­16 November 2018. At CEA's stand, which is number 2004, visitors will also be able to discover:

About the Maison de la simulation

The Maison de la Simulation research center in Paris-Saclay is a joint initiative of CEA, CNRS, Inria, Université de Versailles Saint-Quentin-en-Yvelines and Université Paris-Sud. Its mission is to promote the efficient use of supercomputing equipment by the scientific community at both the national level with GENCI and at European level as part of the PRACE project. The laboratory also aims to develop research in HPC. Training in HPC is a fundamental challenge for research. Six PRACE Advanced Training Centers, including the Maison de la Simulation in France, have been selected to provide these courses in a coordinated manner at the European level. The aim of these centers is to organize training courses covering all the techniques essential for HPC and thus to create a community of users capable of scientifically exploiting supercomputers.
