Paper Abstract

This paper investigates the problems of throughput and reliability encountered in designing multi-computer systems for processing real-time sensor data in the mid-1980 time period. The basic microcomputer and minicomputer building block characteristics are identified; characteristics of ring, crossbar, and banyan interconnection networks are quantified; and the form factors for the resulting multicomputer systems are estimated. Techniques for achieving ultra-reliable computing systems--triple-modular redundancy (TMR), dedicated switched-standby spares, pooled switched-standby spares, and hybrid redundancy--are reviewed and their resulting impact on system design is discussed. The hazard function and its impact on the reliability of systems that must remain dormant for considerable periods are discussed. A technique employing pooled standby with fault tolerance and reconfiguration is concluded to provide the most effective solution where size, weight, and power constraints are most severe.
