Paper Abstract

This paper presents a structure and set of tools to address the needs of groups of scientists working on large, time- dependent simulations. It describes a direct manipulation, 3D steering environment that is integrated with a controller for instrumenting parallel computations, collecting output, and passing it in binary mode between heterogeneous machines. The instrumentation allows collection of data at chosen points in the model and control of the computation through changes of parameters of insertion of alternate data. The steering interface and controller are joined with a library of collaborative communication tools. With these tools a user may steer a simulation and share visualization tools within the group. In addition a time-dependent steering interface has been introduced. Here time is treated on exactly the same basis as the spatial dimensions so there is a 4D environment, 3 shown spatially and one through animation. The steering interface is built upon a flexible visualization/analysis system. This permits the immediate display of time-dependent results from the dynamic simulations and refined interaction with the results to bring out the character and correlations of multivariate data. The user can then launch new simulations at any stage in this exploration using the visualization to define and focus the simulation parameters, region of interest, and time frame.
