Dynamic hardware-assisted software-controlled page placement to manage capacity allocation and sharing within large caches
In future multi-cores, large amounts of delay and power will be spent accessing data in large L2/L3 caches. It has been recently shown that OS-based page coloring allows a non-uni...
