This document discusses and compares several common network topologies for parallel and distributed computing. It describes key properties like degree, diameter, and bisection width for linear arrays, 2D and 3D meshes/toruses, binary trees, and hypercubes. The 3D mesh topology has desirable features like constant degree, relatively low diameter, and high bisection width, making it suitable for interconnection networks in supercomputers. Hypercubes have the highest bisection width but non-constant degree, limiting scalability. Overall, the document analyzes and contrasts popular topology options for parallel computing networks.
