This paper presents an analysis and evaluation of a multicomputer system called SM3 which has a number of special architectural features, viz.: (1) a number of independent computer systems interconnected by a physically partitionable bus which allows the system to be dynamically reconfigured into a number of clusters (or subnetworks) of adjacent computers to achieve a high degree of parallel, MIMD processing; (2) a set of dual switchable main memory modules used to facilitate fast data/command/message transfers among the computers; and (3) a number of special-purpose control lines for efficient interprocessor control, communication, and synchronization. Three representative database algorithms are described and modeled analytically by a set of timing equations and the results of a performance evaluation study are presented. The performance of the SM3 architecture is compared with that of several existing architectures. It is found that SM3 has an excellent overall performance for various categories of database operations and that its architecture is flexible for adapting different software algorithms. 38 references, 5 figures, 3 tables.
