Abstract

In this paper we discuss the parallel implementation of the auction algorithm for the classical assignment problem. We show that the algorithm admits a totally asynchronous implementation and we consider several implementations on a shared memory machine, with varying degrees of synchronization. We also discuss and explore computationally the tradeoffs involved in using asynchronism to reduce the synchronization penalty.
