ABSTRACT:
A mechanism to dynamically migrate a home node of a global page to a more suitable node for improving performance of parallel applications running on a S-COMA and other DSM systems. More specifically, consultation counts are maintained at each client node of a shared memory system, where the consultation count indicates the number of times the client node has consulted the dynamic for lines a page. This information is then used along with other information to decide on whether to change the dynamic home node to a more suitable node.
