Abstract
We present the key features of OPTIMUL (OPTically Interconnected MULtiprocessor) — a multiprocessor architecture that implements a distributed shared memory mechanism using a wavelength division multiplexed (WDM) fiber optic bus. OPTIMUL also supports distributed memory style multiprocessing using the same high-speed message passing mechanism that implements the distributed shared memory. Trace-driven simulation results seem to indicate that efficient performance in the shared and distributed memory modes of operation stem from the operational concurrency of the WDM channels and the high data rate and low latency possible from the use of the new fiber optic receivers and transmitters.
