Abstract :
The authors identify and incorporate the critical factors that influence nonuniform memory access (NUMA) memory management into their performance metrics. Using trace-driven simulations, it is shown that under certain conditions no replication is better than replication. It is also concluded that the effectiveness of replication depends on: (1) the ratio of access times to remote and local memory, (2) virtual address assignment to data, (3) data sharing characteristics, (4) overhead of enforcing consistency, and (5) amount of physical memory available relative to the data sharing characteristics
