Massively parallel augmenting path algorithms for the assignment problem

In this paper we describe how to apply fine grain parallelism to augmenting path algorithms for the dense linear assignment problem. We prove by doing that the technique we suggest, can be efficiently implemented on commercial available, massively parallel computers. Using n processors, our method reduces the computational complexity from the sequentialO(n ³) to the parallel complexity ofO(n ²). Exhaustive experiments are performed on a Maspar MP-2 in order to determine which of the algorithmic flavors that fits best onto this kind of architecture.
