title: Architectural limits on optical-highway-based parallel computing.
abstract: The high bandwidth available in optoelectronic interconnects is often suggested as making them suitable for use in high-performance computer systems. However, it will be shown that for problems where message sizes are small, the latency of an optoelectronic interprocessor interconnect will place a lower limit on the number of processors required to produce performance enhancement over a traditional electronic interconnect.
