• Application of Grid-based computing to coupled
  model systems at multiple scales.
• Midwest Hydrology domain
• Chesapeake Bay domain
• Integration of component models into single
  persistent functional environment.
• Integration of resources via Globus
• Persistence accomplished through CAVERNSoft
• Focus on Accessing the Grid.
• Cave5D/Virtual Director and CAVERNSoft
• Globus/VisAD

Application of Grid-based computing to coupled
model systems at multiple scales

• Chesapeake Bay Domain
• Simulation components for estuarine ecosystem on
  daily to seasonal time scale
• Circulation (FY99)
• Biology (FY00)
• Atmospheric coupling (FY00)
• Collaborative Virtual Environment
• Analysis w/remote sites (FY99)
• Persistence (FY00)
• Simulation Modeling Environment (SME) consists of
  modular, pluggable components using XML
• Linkage w/other models (FY00)

Application of Grid-based computing allowing
desktop access to remote assets
Simulation Configuration The Spatial Modeling
Environment (SME) provides an interface for
desktop access to remote supercomputing resources
via a Java-based configuration manager, shown at
left. Scientists are able to remotely build,
configure, interactively run, control and
visualize complex environmental simulations. One
is able to configure simulation inputs and
outputs, control simulation dynamics and browse
through the objects of a running or paused
simulation. A palette of data viewers supports
many display formats, from the 2D desktop using
VisAD through fully immersive virtual
environments using Cave5D/Virtual Director.
