Abstract: Methods and systems for efficiently managing an application's address space are provided. An application requests physical memory beyond what is permissibly provided by the operating system. The application's virtual memory addresses are efficiently managed so that when access to a memory buffer is desired by the application, the logic required to map the buffer into the application's address space has been substantially completed prior to the application's request. Additionally, a method and system efficiently flushes, in advance of a need by an application, a virtual memory address from the virtual-to-physical memory caches (e.g., TLBs) of multiple processors on which the application is running.
