The main objective of this project is to develop a "point design" for an advanced MIMD computer system capable of achieving at least 100 TeraOPS performance with technology that will definitely become feasible in less than a decade. This design will take advantage of free-space optical technologies to produce a one-dimensional building block (BB) that implements efficiently a large, almost fully-connected system of processors. In addition to having a scaleable architecture, our BB is also technology scaleable, and therefore the number of contained processors in the BB could increase dramatically with expected improvements in optical technologies. A simple two-dimensional structure is proposed for the complete system, where the aforementioned one-dimensional BB is extended into two dimensions. With readily available technology, the word-wide optical interconnection network can be viewed as a mesh of relatively short plastic bars to which interfaces to processor cards are attached. Each processor card contains eight processors interconnected locally with an electronic crossbar. Taking advantage of higher-speed optical technologies, all eight processors share the same optical interface to the two-dimensional system. Its high-level architecture is also scaleable, because it can be extended straight forwardly for any number of dimensions larger than two.

该项目的主要目标是为先进的 MIMD 计算机系统开发“点设计”，该系统能够实现至少 100 TeraOPS 的性能，其技术肯定会在不到十年的时间内变得可行。 该设计将利用自由空间光学技术来生成一维构建块 (BB)，该构建块可有效实现大型、几乎完全连接的处理器系统。 除了具有可扩展的架构之外，我们的 BB 还具有技术可扩展性，因此随着光学技术的预期改进，BB 中包含的处理器数量可能会大幅增加。 为完整的系统提出了一种简单的二维结构，其中上述一维 BB 被扩展到二维。 利用现成的技术，全球光学互连网络可以被视为由相对较短的塑料条组成的网格，处理器卡的接口连接到该塑料条上。 每个处理器卡包含八个处理器，通过电子交叉开关进行本地互连。 利用更高速的光学技术，所有八个处理器共享与二维系统相同的光学接口。 它的高级架构也是可扩展的，因为它可以直接扩展为任意数量的大于二的维度。
