Abstract

We explore the potential of using optical waveguides and switches to build high performance parallel processing systems by introducing a new class of parallel computing architectures. This class of architectures are based on a special kind of reconfigurable buses called segmented buses. A segmented bus is a bus that can be dynamically partitioned into segments, called sub-buses, under program control. Such a bus can be used as a basic building block for constructing powerful parallel architectures. We show that parallel architectures based on segmented buses are versatile by embedding parallel communication patterns supported by a wide variety of networks such as linear array, ring, complete binary tree, X-tree, mesh-of-trees, multidimensional mesh, torus, multigrid and pyramid into segmented bus based architectures, and show that all these networks can be simulated with small slowdown factors.
