Abstract

Computational facilities and applications together continue to grow in their ability to simulate complex physical systems with high fidelity. However, the ultimate success of these endeavors rests not on our ability to simulate the systems but to extract meaning from the results of these simulations. As the amount and complexity of the data generated from these simulations increases, the task of analyzing this data has grown more difficult. Specialized tools and techniques are necessary to effectively analyze the results of today's most ambitious simulation efforts.

The goal of this workshop is to bring together researchers and practitioners in visual analysis and data exploration to identify some of the opportunities and challenges of visual data analysis today and on future petascale systems. The emphasis is on providing tools and techniques applicable to computational science applications, such as those executing on the Department of Energy Leadership Computing Facilities, that will aid in the scientific discovery process.
