In this paper, we present a locality-aware home migration for software distributed shared memory. The goal is to reduce the load on the network caused by managing cached copies of objects and their consistency. Our approach dynamically changes the location of home nodes for each shared object according to localities found in memory access. Our migration system is designed to track the access frequency of objects during a given interval and exploit the locality statistics to adaptively determine the home node of each shared object. We demonstrate the efficiency of our scheme through simulations. The simulation results show that our adaptive home migration decisions result in much lower data traffic than existing home-based protocols for varying locality conditions.
