Abstract
We study the problems of permutation routing and sorting on several models of meshes with fixed and reconfigurable row and column buses. We describe two fast and fairly simple deterministic algorithms for permutation routing on two-dimensional networks, and a more complicated algorithm for multi-dimensional networks. The algorithms are obtained by converting two known off-line routing schemes into deterministic routing algorithms, and they can be implemented on a variety of different models of meshes with buses. We also give a deterministic algorithm for 1–1 sorting whose running time matches that for permutation routing, and another algorithm that matches the bisection lower bound on reconfigurable networks of arbitrary constant dimension.
