An algorithm for dynamic reconfiguration of a multicomputer network

The dynamic reconfiguration of the interconnection network is an advanced feature of some multicomputers to reduce the communication overhead. The authors present an algorithm for the dynamic reconfiguration of the network. Reconfiguration is limited, preserving the original topology. Long distance message passing is minimized by positioning communication partners close to each other. The algorithm is transparent to the application programmer and is not restricted to a particular class of applications, being very well suited for parallel applications whose communication pattern varies over time. The paper also presents some simulation results, showing the benefits from the new reconfiguration algorithm
