VisIt, End User Tool for Visualization and Analysis

Complex simulation efforts require varied postprocessing techniques which are often summarized as "visualization and analysis". The techniques required are diverse: data exploration, visual debugging, quantitative analysis, comparative analysis, and presentation graphics. In addition, a user may frequently go back and forth between any of these activities, causing their distinction to blur, and mandating an integrated environment where a user can seamlessly switch and/or combine modes of operation. This integrated environment also provides a great economy, allowing for file readers, data infrastructure, and routines for slicing and dicing data sets to be used in many contexts.
This poster will describe VisIt, an end user tool for visualization and analysis for large data sets that has been designed to support these varied postprocessing requirements. VisIt is an open source project, and it has received contributions from dozens of developers. VisIt was started, and is actively developed, by the Advanced Simulation and Computing (ASC) program. The project is also developed by and a major delivery vehicle for the Visualization and Analytics Center for Enabling Technologies (VACET) of the Scientific Discovery through Advanced Computing (SciDAC) program.
