This paper describes a moving home method for home-based software distributed shared memory systems. In our system, a home node users records for access to the shared page to determine the moving its role of home. Each time a home node receives a service request for the shared page from a non-home node, it records the node ID and the type of access. If the number of the access records exceeds the threshold of request counts, the home node decides whether the non-home node, which sends the request, is suitable for a new home node of the page. To evaluate our moving method, we have implemented a prototype of DSM system from scratch. The result of our performance evaluation using SPLASH2 benchmark programs shows that our method improved the performance of the system over the fixed home node methods.
