By eliminating most of the human efforts involved in visualizing results through postprocessing, gLucifer reconnects the scientist to the numerical experiment as it unfolds. gLucifer is capable of producing movies of a 4-D data set ‘‘on the fly’’ (simultaneously with running the parallel scientific application) without creating a performance bottleneck. We have developed such a system, gLucifer, using a software framework approach that allows efficient reuse of our efforts in other areas of research. This necessitates the creation of a new visuali- zation system that meets the needs of large-scale geodynamic modeling. Available packages make this assumption of post- processing at quite a fundamental level and are not very well suited for plotting very large numbers of specialized particles. In attempting to write this much data to disk, each computational step introduces a significant performance bottleneck, yet most existing visualization software packages inherently rely on reading data in from a dump file. Thus, the need exists for a new generation of visualization systems able to main- tain parity with the enormous volume of data generated. High-performance computing provides unprecedented capabilities to produce higher resolution 4-D models in a fraction of time.
