Abstract
An operating system (OS) receives a request to allocate a physical memory page to an address space of an application. The OS maintains a data structure that stores references to a plurality of physical memory pages that are available to be allocated, and generates a random index into the data structure, wherein the random index comprises a random number, and wherein the random index corresponds to a first reference for a first physical memory page of the plurality of physical memory pages. The OS selects the first physical memory page of the plurality of memory pages from the data structure using the random index, and maps the first physical memory page to the address space of the application.
