Abstract : An application-independent visualization interaction system is proposed with potential for application-binding at any stage of the modeling process. Advantages of this approach include ease of use, flexibility, code reuse, and modularity. Our design ideas are manifest in the DiSplay system, a graphical user interaction and display library which can be used with any parallel software. We outline its use in the dynamic display of results from computations in queueing simulations, exemplifying synchronization of multiple remote display requests, and the potential for enhanced parallel simulations. We also describe how it may be used to define customized user interaction dialogs for input from an application, and bi-directional interaction between a user and an application.
