The design of a parallel digital computer architecture, the shared-memory optical/electronic computer (SMOEG), and its associated control algorithms are presented. The design is based on the shared-memory model of computation and incorporates an optical interconnection network as an essential element. The arthitecture consists of a novel passive optical shuffle-exchange network, which is detailed in another paper [Appl. Opt. 33, (1994)],.that interconnects electronic processing elements with electronic memory modules and incorporates network control. Improved capability of this optical-electronic multiple-instruction multiple-data (MIMD) architecture over fully electronic implementations stems from the reduced complexity inherent in the optical interconnection network and the resulting memory access capability. In this system the simultaneous development of three main design facets, architecture, hardware, and control algorithms, is crucial in designing an efficient high-performance system.
本文介绍了一种并行数字计算机体系结构——共享内存光/电子计算机（SMOEG）的设计及其相关控制算法。该设计基于共享内存计算模型，并将光互连网络作为一个基本要素。该体系结构由一个新颖的无源光混洗交换网络组成，该网络在另一篇论文[《应用光学》33卷，（1994年）]中有详细介绍，它将电子处理元件与电子存储模块互连，并包含网络控制。这种光电子多指令多数据（MIMD）体系结构相对于全电子实现的改进能力源于光互连网络固有的复杂性降低以及由此产生的内存访问能力。在这个系统中，体系结构、硬件和控制算法这三个主要设计方面的同步开发对于设计一个高效的高性能系统至关重要。
