In Situ Visualization for Computational Science (Dagstuhl Seminar 18271)

Authors: Janine C. Bennett, Hank Childs, Christoph Garth, and Bernd Hentschel

Abstract

In situ visualization, i.e., visualizing simulation data as it is generated, is an emerging processing paradigm in response to trends in the area of high-performance computing. This paradigm holds great promise in its ability to access increased spatio-temporal resolution and leverage extensive computational power. However, the paradigm is also widely viewed as limiting when it comes to exploration-oriented use cases and further will require visualization systems to become more and more complicated and constrained. Additionally, there are many open research topics with in situ visualization. The Dagstuhl seminar 18271 "In Situ Visualization for Computational Science" brought together researchers and practitioners from three communities (computational science, high-performance computing, and scientific visualization) to share interesting findings, to identify lines of open research, and to determine a medium-term research agenda that addresses the most pressing problems. This report summarizes the outcomes and findings of the seminar.

Comparative Visualization Using Cross-Mesh Field Evaluations and Derived Quantities

Authors: Hank Childs, Sean Ahern, Jeremy Meredith, Mark Miller, and Kenneth I. Joy

Published in: Dagstuhl Follow-Ups, Volume 2, Scientific Visualization: Interactions, Features, Metaphors (2011)

Abstract

We present a data-level comparative visualization system that utilizes two key pieces of technology: (1) cross-mesh field evaluation - algorithms to evaluate a field from one mesh onto another - and (2) a highly flexible system for creating new derived quantities. In contrast to previous comparative visualization efforts, which focused on "A-B" comparisons, our system is able to compare many related simulations in a single analysis. Types of possible novel comparisons include comparisons of ensembles of data generated through parameter studies, or comparisons of time-varying data. All portions of the system have been parallelized and our results are applicable to petascale data sets.
