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.

该项目的主要目的是为高级MIMD计算机系统开发一个“点设计”，该系统能够通过技术至少实现100个TERAOPS性能，而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的光学技术来生产一维构建块（BB），该块有效地实现了一个大型，几乎完全连接的处理器系统。 除了具有可扩展的体系结构外，我们的BB还可以扩展技术，因此，BB中包含的处理器的数量可能会大大增加，而光学技术的预期改进。 为完整系统提出了一个简单的二维结构，在该系统中，上述一维BB被扩展到二维。 借助易于使用的技术，单词范围的光学互连网络可以视为相对较短的塑料棒的网格，并将其连接到处理器卡的接口。 每个处理器卡都包含八个与电子横梁本地互连的处理器。 利用高速光学技术，所有八个处理器都与二维系统共享相同的光学接口。 它的高级体系结构也是可扩展的，因为它可以针对大于两个的任何数量的尺寸直接延伸。
