摘要： The systems described herein are configured to enhance the efficiency of memory in a host file system with respect to hosted virtual file systems. In situations when the hosted virtual file systems use smaller file block sizes than the file block sizes of the host file system. During storage of a file, a file block is assigned a block address and unmapping bits. The block address and unmapping bits are stored in a pointer block or other similar data structure associated with the file. Particularly, the block address is stored in a first address block and the unmapping bits are stored in at least one additional address block located in proximity to the block address, such that the unmap granularity of the file is not limited by the fixed size of address blocks in the system.

摘要： A storage controller maintains an allocation space for extent space efficient storage volumes, in response to a request from a host application for storage space, wherein an extent pool is configured to allocate available extents to the host application. In response to a request from the host application to delete data stored in selected extents that are already allocated to the host application, the storage controller deletes the data but continues to maintain the selected extents as being allocated to the host application. In response to a request to write new data, the storage controller writes the new data to the selected extents that are already allocated.

摘要： An apparatus and method are described for coupling a front end core to an accelerator component (e.g., such as a graphics accelerator). For example, an apparatus is described comprising: an accelerator comprising one or more execution units (EUs) to execute a specified set of instructions; and a front end core comprising a translation lookaside buffer (TLB) communicatively coupled to the accelerator and providing memory access services to the accelerator, the memory access services including performing TLB lookup operations to map virtual to physical addresses on behalf of the accelerator and in response to the accelerator requiring access to a system memory.

摘要： In a system having non-uniform memory access architecture, with a plurality of nodes, memory access by entities such as virtual CPUs is estimated by invalidating a selected sub-set of memory units, and then detecting and compiling access statistics, for example by counting the page faults that arise when any virtual CPU accesses an invalidated memory unit. The entities, or pairs of entities, may then be migrated or otherwise co-located on the node for which they have greatest memory locality.

摘要： This disclosure provides techniques of hierarchical address virtualization within a memory controller and configurable block device allocation. By performing address translation only at select hierarchical levels, a memory controller can be designed to have predictable I/O latency, with brief or otherwise negligible logical-to-physical address translation time. In one embodiment, address transition may be implemented entirely with logical gates and look-up tables of a memory controller integrated circuit, without requiring processor cycles. The disclosed virtualization scheme also provides for flexibility in customizing the configuration of virtual storage devices, to present nearly any desired configuration to a host or client.
