Abstract
Still, NUMA-RC does not perform well for migration intensive applications. We propose to augment NUMA-RC further with the ability of migrating data using memory lines that are not actively used. The resulting architecture is termed as EX-NUMA. The extra design overhead of EX-NUMA over NUMA-RC is minimal and is shown to be effective: our simulation results suggest that EX-NUMA outperforms both NUMA-RC and COMA regardless of what type of application is being run.
