Paper Abstract

This paper discusses the need for dynamically reconfigurable interconnection networks in parallel computing systems and describes some of the important physical parameters, limitations and tradeoffs of optical and electronic interconnection architectures. Several optical matrix-vector realizations of generalized crossbar networks are given and compared. These systems may utilize acousto-, electro-, or magneto-optic spatial light modulators as their active switching elements, and moderately large crossbar networks (64x 64 to 512 x 512) appear feasible. Finally, the use of general optical sequential logic architectures to implement crossbar and multistage networks is considered.
