A Note on Dynamic Data Driven Application Simulation (DDDAS) Using Virtual Telemetry

We have immense computing power available at the national supercomputer centers and local clusters of fast PCs. We also have had a proliferation of data acquisition and generation through the deployment of sophisticated new generations of sensors. The lack of coordination between current computational capacity and sensor technology impairs our ability to effectively utilize the continuous flood of information. This is a substantial barrier to achieving the potential benefit computational science can deliver to many application areas including contaminant tracking, which is the target application area of this project. To address this current state we have identified four relatively diverse areas that have common issues that must be addressed for dynamic data driven application simulation (DDDAS) informational and computational sciences to have the promised impact toward addressing important problems. These issues include:
