Abstract: Virtual storage arrays consolidate data storage at a data center for physical and virtual computer systems at one or more branch network locations. Standalone and virtualized computer systems at a branch network location load, execute, and store their operating systems, applications, and data using virtual storage arrays and do not require any built-in or external non-volatile data storage devices such as hard disk drives or solid-state drives at the branch network location. The virtual disks of the virtual storage array are mapped to physical data storage at the data center and accessed via a WAN using storage block-based protocols. A storage block cache at the branch network location includes storage blocks prefetched based on knowledge about the computer systems at the branch network location and the behavior of their operating systems and applications.

Abstract: Methods and apparatus are provided for intercepting a client-server communication connection in a computing environment. A first network intermediary configured to facilitate optimization of client-server transactions may be installed in a path of communications between the client and the server. A second network intermediary configured to cooperate with the first network intermediary is not in the path of communications between the client and the server. The first network intermediary intercepts a connection request from the client and forwards a modified request toward the server. A module within the server intercepts the connection request and redirects it to the second network intermediary. The client-server connection is thus split-terminated at the two network intermediaries, which establish cooperative sessions between themselves and with the client and with the server.

Abstract: Circuitry and method for dividing the frequency of an input clock signal for use in a prescaler of a digital frequency synthesizer. A flip flop is clocked on a first type of edge of the input clock signal, and provides an output for use as a divided clock signal. Feedback circuitry is clocked on the first type of edge of the input clock signal and provides a signal to a data input of the flip flop based on the inverse of the output of the flip flop.

Abstract: In a system where transactions are accelerated with asynchronous writes that require acknowledgements, with pre-acknowledging writes at a source of the writes, a destination-side transaction accelerator includes a queue for queue writes to a destination, at least some of the writes being pre-acknowledged by a source-side transaction accelerator prior to the write completing at the destination, a memory for storing a status of a destination-side queue and possibly other determinants, and logic for signaling to the source-side transaction accelerator with instructions to alter pre-acknowledgement rules to hold off on and pursue pre-acknowledgements based on the destination-side queue status. The rules can take into account adjusting the flow of pre-acknowledged requests or pre-acknowledgements at the sender-side transaction accelerator based at least on the computed logical length.

Abstract: An analytic system may have a number of processing stages. One or more data sources may provide data to a first processing stage. The first processing stage may specify one or more data contracts having a schema describing a layout and types of data provided by the one or more data sources. Each of the processing stages may specify a respective data contract having a schema such that the processing stages may understand a layout and types of data provided as input to the processing stages. The data contracts me further specify a valid range of values for various items of data described by schemas. Data not conforming to a data contract may be automatically filtered out such that a corresponding processing stage may not be provided with the non-conforming data.

Abstract: Methods, systems, and apparatus, including computer program products, for generating synthetic queries using seed queries and structural similarity between documents are described. In one aspect, a method includes identifying embedded coding fragments (e.g., HTML tag) from a structured document and a seed query; generating one or more query templates, each query template corresponding to at least one coding fragment, the query template including a generative rule to be used in generating candidate synthetic queries; generating the candidate synthetic queries by applying the query templates to other documents that are hosted on the same web site as the document; identifying terms that match structure of the query templates as candidate synthetic queries; measuring a performance for each of the candidate synthetic queries; and designating as synthetic queries the candidate synthetic queries that have performance measurements exceeding a performance threshold.

Abstract: Described herein are various principles for operating a transmitter circuit to reduce noise affecting a signal being generated and reducing jitter. In some embodiments, a circuit is operated in a way that switching occurs at or above a bit rate of transmission, such that at least one switch changes state at least for every bit. Operating the circuit in such a way leads to a switching rate that is above a resonant frequency of the circuit and prevents large oscillations and noise from being inserted into the signal and causing communication problems.

Abstract: A hypervisor receives an interrupt that includes a target address and, in turn, branches to an administrating interrupt vector. Next, the administrating interrupt vector determines whether to branch to a piggyback interrupt handler corresponding to a piggyback interrupt vector. Based upon the determination, the hypervisor either branches to the piggyback interrupt handler or to an administrating interrupt handler that corresponds to the administrating interrupt vector.
