Programming Middle Tier of a Computational Grid
We will copy a much reviled model -- Microsoft Word or PowerPoint -- Problem Solving Environments for document preparation -- for Gateway programming toolbox
Computing abstracted as a set of hierarchical Toolbars Toolbars are defined in XML and rendered in HTML for user interface. XML interpreted on middle tier as some suitable service.
Computing Toolbars include user profile, results, visualization (where “command” could be AVS), collaboration, programming model, HPF, Dataflow, resource specification, resource status, code (application specific)
