We present the design of a wavelength division multiplexed fiber optic bus for multiprocessors that allows both the shared memory model and the distributed memory model to be supported efficiently. We establish this by presenting the results of a fairly detailed trace-driven simulation of the performance of a system using the proposed interconnection. We also discuss some of the engineering issues involved in the design of such a WDM fiber bus and briefly mention approaches for cutting down on the cost of the optonic interface components. Our results seem to indicate that efficient performance in the shared and distributed memory modes of operation stems from the operational concurrency of the WDM channels and the high data rate and low latency possible from the use of the new fiber channel optical receivers and transmitters
