InfoSymbiotics embodies the power of Dynamic Data Driven Applications Systems (DDDAS), a concept whereby application simulation models are dynamically integrated in a feed-back loop with the real-time data-acquisition and control components of the application system. Advanced capabilities can be created through such new computational approaches and new instrumentation methods. New modeling and simulation capabilities include: enhancing the accuracy of the application computational model by complementing and augmenting the application model with on-line measurement-data, streamed into the model at execution time and in targeted parts of the solution phase-space; or replace parts of the computation with instrumentation data streamed into the model at execution time, thus speeding-up the computation to either allow more comprehensive models of a system, or create decision support systems with the accuracy of full-scale simulations. Moreover, the notion of the executing application selectively guiding instrumentation processes, creates more efficient and effective measurement and data management capabilities, including the challenges of how to architect and dynamically manage large numbers of heterogeneous sensors and controllers; rather than the static and ad-hoc ways of today,with DDDAS these sets of resources and be managed dynamically and adaptively, and in optimized ways. The talk will present these concepts as well as a research agenda for creating these new capabilities and in the context of application areas where InfoSymbiotics/DDDAS can have transformative impact.
