This paper presents a proper direction of the development of single computer organization, which is a focus on features like a generalized interconnection of memories, or as specialized computers with geometrically related memory interconnections and controlled by one or more instruction streams. The arguments to support this are based on statistical characteristics of computation on computers over the last decade and upon the operational requirements within problems of the physical interest.
To begin with, the effort expended on achieving high parallel processing rates is wasted unless it is accompanied by achievements in sequential processing rates of very nearly the same magnitude. Besides, the physical problems which are of practical interest tend to have significant complications. To sum up the effects of data management housekeeping and of problem irregularities, the author has compared three different machine organizations involving approximately equal amounts of hardware. Also, the classic performance versus cost of computers is also discussed in this paper.
