In classical massively parallel computers, the complexity of the interconnection networks is much higher than the complexity of the processing elements themselves. Optical interconnections may provide a way to reconsider very large parallel architectures. We compare some optically interconnected parallel multicomputer models with regard to their communication capabilities. We first establish a distinction of such systems, based on the independence of the communication elements embedded in the processors (transmitters and receivers). Then, motivated by the fact that in multicomputers some communication operations have to be very efficiently performed, we study two fundamental communication problems, namely, one-to-all and all-to-all, under the hypothesis of bounded fanout. Our results take also into account a bounded number of available wavelengths.
