Paper Abstract

The principles of scalable computing have been used in an investigation of the application of high speed data networks and remote computer resources in providing visualization tools for research and development activities. The architecture of a distributed visualization system that can utilize either shared memory or message passing paradigms is described. The three components of the system can be physically separated if network communication is provided. A flexible data cache server is used to accommodate newly computed data or data from an earlier experiment or computation. An image specification toolset, implemented for parallel/distributed architectures using PVM, includes methods of calculating common visualization forms such as vector fields, surfaces or streamlines from cache data. An image generation library, implemented for workstations and high performance PCs, receives the data objects and provides investigators with flexibility in image display. The system has been operated with several combinations of distributed and parallel processor machines connected by networks of different bandwidths and capacities. Observations on the performance and flexibility of different system architectures are given.
