Abstract
In a computing system including an application executing on top of a virtualization control layer, wherein the virtualization control layer maps portions of a virtual memory to portions of a physical memory, a method for managing memory including: identifying, by the application, a range of virtual memory whose probability of being replicated in the virtual memory exceeds a given threshold; obtaining, by the application, at least one memory address corresponding to the range of virtual memory; and passing, from the application to the virtualization control layer, an identifier for the range of virtual memory and the memory address corresponding to the range of virtual memory, wherein the identifier is useable by the virtualization control layer to identify similar ranges within the virtual memory.
