Abstract: Distributed I/O virtualization includes receiving, at a first physical node in a plurality of physical nodes, an indication of a request to transfer data from an I/O device on the first physical node to a set of guest physical addresses. An operating system is executing collectively across the plurality of physical nodes. It further includes writing data from the I/O device to one or more portions of physical memory local to the first physical node. It further includes mapping the set of guest physical addresses to the written one or more portions of physical memory local to the first physical node.

Abstract: Handling frequently accessed pages is disclosed. An indication is received of a stalling event caused by a requested portion of memory being inaccessible. It is determined that the requested portion of memory is a frequently updated portion of memory. The stalling event is handled based at least in part on the determination that the requested portion of memory is a frequently updated portion of memory.

Abstract: A process includes creating, by a kernel of a distributed system, entries in a storage replica table, which are associated with a guest physical memory address. The process includes storing, by the kernel, data in the entries associating the entries with respective versions of content for the guest physical memory address; storing, by the kernel, data in the entries associating the entries with respective stable storage block addresses; and storing, by the kernel, data in the entries associating the entries with respective real physical memory addresses. The process includes, responsive to a read request to read content associated with a first version of the versions, accessing, by the kernel, the storage replica table. The process includes, responsive to the accessing the storage replica table, identifying, by the kernel, a first entry of the entries associated with the first version. The first entry contains data associating the first entry with a first real physical memory address.

Abstract: In some examples, a distributed system includes a plurality of computer nodes comprising respective physical input/output (I/O) interfaces to a network-attached storage system. A virtual I/O interface is between a distributed virtual management program and a guest operating system (OS) of a virtual machine (VM). A plurality of virtual processors access the network-attached storage system through the virtual I/O interface in parallel using the respective physical I/O interfaces, where a first virtual processor in a first computer node is to use a data structure in the virtual I/O interface to submit a request to access data in the network-attached storage system and to receive a result of the request, and where the access of data from the network-attached storage system to satisfy the request is performed locally at the first computer node using the physical I/O interface of the first computer node.

Abstract: Hierarchical stalling strategies are disclosed. An indication is received of a stalling event caused by a requested resource being inaccessible. In response to receiving the indication of the stalling event, a set of cost functions usable to determine how to handle the stalling event is selected based at least in part on a type of the stalling event. The stalling event is handled based at least in part on an evaluation of the set of cost functions selected based at least in part on the type of the stalling event.

Abstract: A method, system, and computer program product provide the ability to connect online and offline activity. Advertisement delivery information is acquired. The advertisement delivery information includes an advertisement identification and a user identification identifying a user to which the advertisement was delivered. Beacon information is acquired. The beacon information includes a beacon identification and location. The beacon identification and the device identification are received from an application executing on a first device associated with the user. The application receives the low energy signal from the beacon identified by the beacon identification. Based on the advertisement delivery information, beacon identification, and device identification, conversion of the advertisement is directly attributed. Conversion information based on the conversion is then provided.

Abstract: In a television system in which at least program title information for programs which are to be transmitted in the future is transmitted in advance to form a channel guide listing, apparatus is provided for searching the listing for specific user-entered information, and upon successful conclusion to the search, the apparatus schedules the tuning of the desired program, or in the alternative, notifies the viewer of the availability of the program. In those instances where descriptive text accompanies the program listing, apparatus of the invention performs a search of the text for a particular text string which may relate to the title, the star, the director, or the context of the program, among other search criteria.
