An Implementation of a Distributed Interactive Graphics System for a Supercomputer Environment

摘要

We describe the design, implementation, and performance of a distributed interactive graphics software system. The software is distributed between two machines with very different capabilities, a supercomputer (Cray-2) and a graphics workstation (Silicon Graphics Iris). Both machines run the same operating system (unix) and are programmed by the user. Three dimensional graphical transformations, display updates, the user interface, and related operations are handled by the graphics workstation, while computationally intensive operations and some graphics are performed by the supercomputer. Communication between the two machines consists of a remote graphics protocol using TCP/IP as the transport layer.
