A major problem for modern four dimensional computational simulations is that they generate large volumes of data at a much faster rate than can be effectively processed using standard storage and visualization techniques. We are in the process of building an advanced system for interactive, real-time visualization of the output from computational planetary dynamo simulations. The dynamo code is a modified version of Magic2 (J. Wicht, Phys. Earth Planet. Int., in press, 2002). Time-scaling of typical dynamo simulations is such that it is presently feasible to observe the motion of convection and magnetic variations in the real time numerical output, similar to a laboratory experiment. The visualization system is designed to run relatively independently of the dynamo code. In particular, the system architecture allows three-dimensional rendering of scalar and vector fields to occur independently of the data production process. Thus data production delays do not cause delays in manipulation of the visual representation, such as object rotation and data queries. In fact, for truly immersive applications the display refresh rate should be on the order of 10 Hz minimum. The main components of the system are 1) the simulation program; 2) the solution server; 3) the solution formatter; and 4) the visualization program. Here the simulation program is the dynamo code. The solution server controls which data from the simulation will be processed, thus helping to solve the problem of large data volume. The solution formatter converts simulation output for further processing by the visualization program. The subsystems 1), 2) and 3), are run on a large multiprocessor shared memory parallel (SMP) machine whereas subsystem 4) may be run on a remote PC or workstation. The data transfer from the SMP machine to the PC is facilitated by data compression and a high speed link of 1 gigabits per second. This system architecture will allow us to visualize key diagnostics in the dynamo simulations in real time, which will greatly facilitate output computational efficiency and understanding of run results. The relative independence of the visualization system from the simulation code makes it amenable for future application to different computational dynamics simulation codes.
