Abstract : EnSight is a commercially available, general purpose visualization program currently used at a variety of DOD and commercial research facilities. The software was originally designed and implemented for the vector based Cray computer systems. The advent of reasonably affordable parallel computers configured as symmetric multiprocessors has enabled advanced government and commercial research groups to perform computational analyses on solution sets consisting of several million grid nodes. Unfortunately, the ability to generate these massive data sets has outstripped the ability to interactively visualize them. The first goal of this project was to optimize the EnSight software for efficient sreamline generation in a steady-state vector field. After initialization, the streamline generation is a parallel task as each particle path is independent of any other path.
