Abstract:
Advances in computing technology, particularly in the field of microprocessor design, have enabled natural sciences CFD simulations to be carried out at unprecedented scales, yielding torrents of numerical data. However, for many CFD researchers the greatest challenge now faced is not performing the simulation, but extracting meaningful information from the outputs that result. This talk will describe our approach to addressing this problem by exploiting the power of progressive data access (PDA). Our novel, wavelet-based PDA scheme enables the exploration and manipulation of terascale size data sets using only a commodity, desktop PC. We have created a prototype analysis system that combines advanced 3D visualization with traditional statistical analysis capabilities to create a powerful environment for investigating large, CFD data sets. With NSF ITR funding we will develop our prototype into a robust, open source tool suite, freely available to the scientific community.
