A heuristic approach for embedding communication patterns in an interconnection cached parallel processing network

Abstract

The problem of identifying whether a graph has a bounded l-contraction for a given integer l is known to be NP-complete for l>2. The authors describe a heuristic approach based on simulated annealing to approximate the solution of this problem. Performance results of their algorithm on graphs representing classical topologies (e.g. trees, grids, hypercubes and cube connected cycles), are presented as well.<>
