Multiple channel architecture

Abstract

A parallel processing architecture based on multiple-channel optical communication is described. A large number of independent, selectable channels (or virtual buses) are available using a single optical fiber. Arbitrary interconnection patterns, as well as machine partitions, can be emulated by using appropriate channel assignments. Hierarchies of parallel architectures and simultaneous execution of parallel tasks are also possible. Recent technological advances in semiconductor laser technology that make such a parallel architecture possible, a basic system overview, various channel allocation strategies, and a summary of advantages compared with traditional interconnection techniques are presented.<>
