Direct Simulation of Engineering Problems with a Fast Array Computer : 3rd Report, System of Data Transmission between Arithmetic Units In the Array Computer

Abstract

To shorten the time consumed for design computations in many engineering branches, the authors intend to use a new type computer system called array computer, which has hundreds of arithmetic units (AUs) connected in a multi-dimensional network. The most important, but difficult problem in design of this array computer is the development of an effective system of parallel data transmission between AUs. Hence this report deals with the development of this system, comparing the data transmission efficiencies of many conceivable systems. The results show that the effective arrangement of AUs is, (1) four- or five-dimensional array in the case of 1024 AUs, and (2) four- or six-dimensional array in the case of 4096 AUs. In both cases each AU is connected directly via data transmission lines with all AUs which lie on all coordinate axes passing through itself.
