Abstract: A method is described. The method includes receiving notice of a page fault. A page targeted by a memory access instruction that resulted in the page fault residing in persistent memory without system memory status. In response to the page fault, updating page table information to include a translation that points to the page in persistent memory such that the page changes to system memory status without moving the page and system memory expands to include the page in persistent memory.

Abstract: A host based caching technique may be used to determine caching policies for a hybrid hard disk drive. Because the host based caching may make use of knowledge about what data is being cached, improved performance may be achieved in some cases.

Abstract: A processor is described. The processor includes register space to accept input parameters of a software command to move a data item out of computer system storage and into persistent system memory. The input parameters include an identifier of a software process that desires access to the data item in the persistent system memory and a virtual address of the data item referred to by the software process.

Abstract: Examples include techniques for emulating a non-volatile dual inline memory module (NVDIMM) in a computing platform using a non-volatile storage device. When a power up event occurs for the computing platform, a host memory buffer may be allocated in a system memory device and a backing store for the host memory buffer may be copied from the non-volatile storage device to the host memory buffer in the system memory device. When a power down event or a flush event occurs for the computing platform, the host memory buffer may be copied from the system memory device to the corresponding backing store for the host memory buffer in the non-volatile storage device. Thus, virtual NVDIMM functionality may be provided without having NVDIMM hardware in the computing platform.
