Book excerpt: General problems involved in the synthesis and performance of special-purpose multicomputer systems are discussed. Three trends in the organization of joint operation of computers are distinguished: (1) Joint operation of a few existing various general-purpose computers; (2) Joint operation of a few identical general-purpose computers; (3) A special-purpose computing system (SPCS) which may consist of different or identical computers. Parallel and sometimes series-parallel algorithms are most suitable for SPCS; their efficiency can be evaluated by the minimum algorithm length and the total number of required operations. These indices of performance of SPCA are considered: (a) productivity, i.e., the net machine time spent in solving a problem; (b) productivity ratio, i.e., the ratio of the time required to solve a problem by one computer to the time required to solve the same problem by SPCS consisting of identical computers; (c) structural suitability of algorithm to SPCS; (d) utilization factor of SPCS; (e) complexity and economy of SPCS.
