摘要： Embodiments of apparatuses, methods, and systems for partitioning memory mapped device configuration space are disclosed. In one embodiment, an apparatus includes a configuration space address storage location, an access map storage location, and addressing logic. The configuration space address storage location is to store a pointer to a memory region to which transactions to configure devices in a partition of a partitioned system are addressed. The access map storage location is to store an access map or a pointer to an access map. The addressing logic is to use the access map to determine whether a configuration transaction from a processor to one of the devices is to be allowed.

摘要： A method, apparatus and system are described for seamlessly and concurrently sharing a graphics device amongst multiple virtual machines (“VMs”) on a host computer. Specifically, according to one embodiment of the invention, a graphics device may be shared by multiple VMs such that only the output of one VM (i.e., the “focus VM”) is displayed on a display device coupled to the host computer. The focus VM may be identified according to a variety of ways. The focus VM may render its output into a frame-buffer and/or an overlay buffer, and the page table entries (“PTEs) that point to the frame-buffer may then be copied to a display buffer in an unused memory location associated with the focus VM. The PTEs may additionally be copied to display buffers in unused memory locations associated with the non-focus VMs on the host. The display buffer may then output its display (via the pointers to the frame buffers) to the display device. This output remains that of the focus VM until a different VM is selected as the new focus VM. The process may then repeat itself.

摘要： In one implementation, a computer-implemented method includes receiving at information related to users of a social network site, and determining a social network graph for at least a portion of the social network, the graph including a plurality of nodes connected by links, each node corresponding to a user that has a profile page on the social network. The method can also include identifying first nodes from the plurality of nodes as including content associated with a particular subject of interest, and seeding the identified first nodes with first scores. The method can additionally include determining second scores for second nodes based on propagation of the first scores from the first nodes to the second nodes using the links of the social network graph; and providing the determined second scores for the second nodes.
