VIRTUALIZED MEMORY PAGING USING RANDOM ACCESS PERSISTENT MEMORY DEVICES

Abstract:

Systems for virtual memory computing systems. A set of hardware or software operational elements of a computing system performs virtualized memory paging. The operational elements serve to identify a random access memory device and at least one random access persistent memory device (RAPM) in a computing system. The random access persistent memory device is configured as a swap device that is apportioned as having at least some address space for swap. At least some of the swap address space is assigned to one or more virtualized entities in the computing system. When a page swap event is detected by the computing system, one or more of the operational elements execute one or more paging operations based on characteristics of the page swap event. The paging operations perform swap-in or swap-out of at least one page between the random access memory device and the random access persistent memory device.
