Abstract:

Extreme Data Management, Analysis, and Visualization for Scientific Discovery and Economic Development

Effective use of data management techniques for the analysis and visualization of massive data models is crucial for the success of any supercomputing center, for creating a data-intensive scientific investigation cyberinfrastructure, and for a growing number of industrial endeavors. As exascale computing progresses, data movement challenges have fostered innovation leading to complex streaming workflows which take advantage of being able to process in-motion data. This technology is also being used to more broadly investigate sensing data and is being deployed in commercial products, with direct economic and societal impact.

The techniques developed at the Center for Extreme Data Management Analysis and Visualization (CEDMAV) allow for the building of a scalable data movement infrastructure for fast I/O while organizing the data in a way that makes it immediately accessible for analytics and visualization. In this talk I will share not only these techniques, but also a topological analytics framework that allows for processing data in-situ and for achieving massive data reductions while maintaining the ability to explore the full parameter space for a featured selection. Overall, this technological innovation leads to a flexible data streaming workflow that allows for working with massive simulation models without compromising the interactive nature of the exploratory process that is characteristic of the most effective data analytics and visualization environment. These data streaming technologies are increasingly useful in experimental facilities, e.g., microscopes used in neuroscientific research, and synchrotron light sources for materials science. The distributed deployment of these technologies is poised to provide cost effective solutions in fields such as precision agriculture, surveillance, telemedicine, and many others as well.
