This paper gives an overview of the grid based Engineering Design Problem Solving Environment (PSE) being developed at Southampton University. Following some background comments on PSE definition and function, the conceptual architecture of a PSE tool developed jointly with Cardiff University is shown. This has been integrated with the Engineering Design PSE using the Cardiff VCCE and XML component model. Essentially, VCCE forms a GUI front-end to our PSE and provides the ability to setup and execute a computation by creating a task graph from available components via drag and drop operations on a sketchpad display. A detailed description of the PSE component structure is presented next, with particular reference to the form and type of communication required between components. To overcome some communications restrictions and to provide the framework for a generic PSE system, a more general communications sub-system is being developed, based on a message passing design, using CORBA calls for component communication within an intranet cluster and using XML/SOAP for component communication across intranets.

As developed, the current PSE will be able to compute single or multi-point design evaluations over network clusters. However, in order to fully exploit parallel computation over intranet or even internet clusters and to provide an environment which more naturally meets the data-centric view of users, two additional major enhancements to the PSE are planned. The first concerns scheduling and task farming. The ultimate goal is to achieve within the PSE, an asynchronous computational workflow pattern where analysis tasks can seek to exploit whatever computational resources are available in various workstation clusters (i.e., task farming), running independently of search/optimisation tasks. The second enhancement concerns computational resource control and job control and the setting up of an Engineering Design Grid Portal. Some consideration is also given to the need to move towards a full server-side component model, particularly when the PSE has to cope with multiuser access to distributed databases.
