We consider the problem of realizing several common communication structures in the all-optical Partitioned Optical Passive Stars (POPS) topology. We show that, often, the obvious or “natural” method of implementing a communication pattern in the POPS does not efficiently utilize its communication capabilities. We present techniques which distribute the(More)
This paper presents a scalable electro-optical interconnection network architecture which is suitable for tightly coupled multiprocessors. The architecture is called a Partitioned Optical Passive Star (POPS). It is a type of multiple passive star topology in which only constant and symmetric coupler fanouts are used and in which exactly one coupler is(More)

This paper presents and analyzes a topological approach to providing multiple data channels using current technologies. The Partitioned Optical Passive Stars (POPS) topology is an all-optical interconnection architecture that uses multiple non-hierarchical couplers. POPS topologies provide powerful con gurability for optimization of system complexity,(More)
We consider the problem of embedding ring and torus communication structures onto the all-optical Partitioned Optical Passive Stars (POPS) topology. We show that the natural embedding, which maps the nodes in the ring or torus directly onto the POPS, does not result in an optimal embedding, and thus does not eeciently utilize the communication capabilities(More)
