Visualization and Data Management

One of the central challenges in modern science is the ability to quickly derive knowledge and understanding from large, complex collections of data. We present a novel approach to solve this problem that combines and extends techniques from high performance visual data analysis and scientific data management. This approach is demonstrated within the context of gaining insight from complex, time-varying datasets produced by a laser wakefield accelerator simulation. Our approach leverages histogram-based parallel coordinates for both visual information display as well as a vehicle for guiding a data mining operation. Data extraction and subsetting is implemented with state-of-the-art index/query technology. This approach, while applied here to accelerator science, is generally applicable to a broad set of science applications, and is implemented in a production-quality visual data analysis infrastructure. We conduct an extensive performance analysis and demonstrate good scalability on a distributed memory Cray XT4 system.
