A high performance graphics system for the CRAY-1

Abstract

This paper describes the design and implementation of a state-of-the-art interactive vector graphics system connected to the CRAY-I supercomputer.The primary design goal for this graphics system is that it support large hydrodynamic computer programs used in weapons design calculations. The interactive use of these programs requires displays consisting of up to 20,000 vectors, extensive interaction tools, and highbandwidth conu~unication rates. The major system components selected for this project were an Evans and Sutherland Picture System 2 and a Digital Equipment Corporation (DEC) PDP-11/70 and PDP-I1/34 running the UNIX operating system. This paper presents the system design goals and performance criteria. The hardware/software systems chosen for this project are reviewed, and the integration of this system into the Los Alamos Scientific Laboratory's (LASL) Integrated Computer Network (ICN) is described. This implementation involved most areas of applied computing, including computer graphics, communications, distributed processing, and computer security. The level of effort required for this implementation is described, and the results and benefits are presente~.Future plans for this system are also briefly described.

Visual Supercomputing: Technologies, Applications and Challenges

“…Elwald and Mass's vector graphics library for Cray‐1 [17] represents the earliest efforts for providing visualization capability to support scientific computation on supercomputers. Since then, there has been a huge volume of publications devoted to parallel architectures and algorithms for computer graphics and visualization.…”
