The invention is a modular backup and retrieval system. The software modules making up the backup and retrieval system run independently, and can run either on the same computing devices or on different computing devices. The modular software system coordinates and performs backups of various computing devices communicating to the modules. Actions of modules on one of the computing devices acts as a system manager for a network backup regimen. A management component acts as a manager for the archival and restoration of the computing devices on the network. It manages and allocates library media usage, maintains backup scheduling and levels, and supervises or maintains the archives themselves through pruning or aging policies. The management component is not hard wired in its functionality, but may adapt to changing circumstances in these policies. A second software module acts as a manager for each particular library media.

The invention addresses the management of multiple operating systems on a single computer and other boot-time problems. A boot-time graphical user interface is described, including support for menus, tabs, non-ASCII characters, and other graphical user interface components in the pre-boot environment. Approaches to organizing the storage and selection of multiple operating system are also presented, including the use of multiple directories which are identified in operating system boot sectors.

The invention provides a system and method for receiving weather forecast information in a mobile unit (MU) and using that information to warn a user of a future weather hazard with reference to the MU's location and/or intended direction of travel. A hazard location algorithm compares a forecast location of each MU with a forecast hazard and transmits a warning to each MU that is predicted to encounter the hazard. As the MU moves, its actual position is updated in the forecasting center, and a revised warning is transmitted to the MU. The hazard information may be displayed on the user's system in the form of a rotating map with an automatically adjustable range to display warning information in relation to the system's location. Warnings, including audio warnings for playback and crawls for display on a television, can be automatically generated and spoken or displayed to a user.

A server management apparatus for lowering migration costs during scale-in/scale-out and workload consolidation of a cluster system(s) to thereby reduce power consumption is disclosed. The apparatus manages a physical server group which renders operative a virtual server group thereon and, when putting into practice a cluster system including a plurality of virtual servers placed in the physical server group, manages the layout state of virtual servers pursuant to the load state of the virtual server group. When executing scale-in, a virtual server operating on a physical server with the minimum number of operative virtual servers is specified as a shutdown target. When executing scale-out, a workload variation is predicted to control a scale-out destination of cluster system so that load variation-resembled cluster systems gather on the same physical server. The scale-in execution timing is delayed if the predicted load variation tends to rise and accelerated if it falls.

System and method for modeling a nonlinear process. A combined model for predictive optimization or control of a nonlinear process includes a nonlinear approximator, coupled to a parameterized dynamic or static model, operable to model the nonlinear process. The nonlinear approximator receives process inputs, and generates parameters for the parameterized dynamic model. The parameterized dynamic model receives the parameters and process inputs, and generates predicted process outputs based on the parameters and process inputs, where the predicted process outputs are useable to analyze and/or control the nonlinear process. The combined model may be trained in an integrated manner, e.g., substantially concurrently, by identifying process inputs and outputs (I/O), collecting data for process I/O, determining constraints on model behavior from prior knowledge, formulating an optimization problem, executing an optimization algorithm to determine model parameters subject to the determined constraints, and verifying the compliance of the model with the constraints.

Concurrently branch predicting for multiple branch-type instructions demands of high performance environments. Concurrently branch predicting for multiple branch-type instructions provides the instruction flow for a high bandwidth pipeline utilized in advanced performance environments. Branch predictions are concurrently generated for multiple branch-type instructions. The concurrently generated branch predictions are then supplied for further processing of the corresponding branch-type instructions.

The invention provides tools and techniques for migration of user profiles in place on a computer. In one method, a first step provides a migration content storage partition to hold migration content such as user settings. This partition is provided by using a partition manipulation tool to obtain sufficient space on the computer. A second step saves migration content into the provided partition. A third step deploys an image into another partition on the computer, overwriting that partition. A fourth step then uses the migration tool to restore migration content from the migration content storage partition into the newly imaged partition, thereby customizing the new image with at least some of the former image's user settings. The migration content storage partition may then be deleted, or it may be retained and made available to the user as additional storage.

Embodiments of the invention are directed to producing spike-timing dependent plasticity using electronic neurons for computation, and pattern matching tasks such as association and recall. In response to an electronic neuron spiking, a spiking signal is sent from the electronic neuron to each axon driver and each dendrite driver connected to the spiking electronic neuron. Each axon driver receiving the spiking signal sends an axonal signal from the axon driver to a variable state resistor. Each dendrite driver receiving the spiking signal sends a dendritic signal from the dendrite driver to the variable state resistor, wherein the variable state resistor couples the axon driver and the dendrite driver. The combination of the axonal and dendritic signals is capable of increasing or decreasing conductance of the variable state resistor.

A system enables indirect determination of a position vector (V_R) of a point position (P). The system uses two fixed trackers (10 and 10′) whose absolute positions are known. A movable measuring device (20) provides a rigid rod (25) supporting a pair of reflectors (30 and 30′) which are mounted at fixed positions. A reference point (R) is mounted at a further fixed position on the rod (25) and is on a straight line (L) through the reflectors (30 and 30′). Light beams from the trackers (10 and 10′) acquire the reflectors (30 and 30′) so that when the reference point (R) is positioned at the point position (P), the position vector (V_R) of point position (P) is determinate by vector addition.

The present invention provides a unique system and method that facilitates reducing network traffic between a plurality of servers located on a social-based network. The system and method involve identifying a plurality of vertices or service users on the network with respect to their server or network locations. The vertices' contacts or connections can be located or determined as well. In order to minimize communication traffic, the vertices and their connections with respect to their respective server locations can be analyzed to determine whether at least a subset of nodes should be moved or relocated to another server to facilitate mitigating network traffic while balancing user load among the various servers or parts of the network. Thus, an underlying social network can be effectively partitioned. In addition, the network can be parsed into a collection of nested layers, whereby each successively less dense layer can be partitioned with respect to the previous (partitioned) more dense layer.

Some embodiments provide an optimized multi-hit caching technique that minimizes the performance impact associated with caching of long-tail content while retaining much of the efficiency and minimal overhead associated with first hit caching in determining when to cache content. The optimized multi-hit caching utilizes a modified bloom filter implementation that performs flushing and state rolling to delete indices representing stale content from a bit array used to track hit counts without affecting identification of other content that may be represented with indices overlapping with those representing the stale content. Specifically, a copy of the bit array is stored prior to flushing the bit array so as to avoid losing track of previously requested and cached content when flushing the bit arrays and the flushing is performed to remove the bit indices representing stale content from the bit array and to minimize the possibility of a false positive.

A method and system for using a peripheral device identifier obtained from a peripheral device to determine a network address from a database, or generate the network address based on the identifier. Information related to the peripheral device is obtained from a remote device at the network address. The method includes automatically transferring at least one identifier from the peripheral device to a host device when the peripheral device is connected to the host device. The step of transferring is preferably done during or after enumeration of the peripheral device, such as occurs when a USB device is connected to a computer. The identifier is used as an index to automatically determine a network address from a database on the host device or a remote device, or to automatically generate a network address. Then, communication occurs between the host device and a remote device or other source of the information indicated by the network address. For example, the host device may download a device driver for the peripheral device from the remote device or from another peripheral device connected to the host device indicated by the network address.

The system and method for structuring self-provisioning workloads deployed in virtualized data centers described herein may provide a scalable architecture that can inject intelligence and embed policies into managed workloads to provision and tune resources allocated to the managed workloads, thereby enhancing workload portability across various cloud and virtualized data centers. In particular, the self-provisioning workloads may have a packaged software stack that includes resource utilization instrumentation to collect utilization metrics from physical resources that a virtualization host allocates to the workload, a resource management policy engine to communicate with the virtualization host to effect tuning the physical resources allocated to the workload, and a mapping that the resource management policy engine references to request tuning the physical resources allocated to the workload from a management domain associated with the virtualization host.

A management system for managing a plurality of computers and a plurality of pieces of software in a computer center includes: a selection data storage part for storing data regarding allocation destination selection, the data including at least either one of operation data and temperature data, wherein the operation data represent states of execution of the pieces of software by the computers, respectively, and temperature data represent temperature distribution in the computers; an instruction generation part for extracting an overheated computer that is assumed to emit more heat as compared with the other computers, and a less-heated computer that is assumed to emit less heat as compared with the other computers, by using the data regarding allocation destination selection, and generating an instruction for relocating at least a part of a piece of software allocated to the overheated computer to the less-heated computer; and an instruction part for outputting the instruction. This makes it possible to save energy for cooling the computers.

When a shutter button of a digital camera is pressed, a picture signal fetched from a CCD is converted to a digital signal and compressed and written into a nonvolatile memory means like a flash memory card as a picture file which can be identified uniquely. By turning on a reproduction switch, a picture file is read out from the nonvolatile memory means, the compressed data is expanded and converted to an analog signal, and the converted picture is displayed on a liquid crystal display. By pressing a display feed key, another picture file is read out and displayed. A user can produce a control file for controlling print processing, display processing, transmission processing and the like for the picture file by selecting a particular picture file using an operation key. The nonvolatile memory means can be removed. By mounting this memory means on a printer unit, display unit or picture transmission unit, the digital camera also can be used during print, display or transmission of the picture. If multi-screen print is carried out on the printer unit, a vertical direction of each picture is unified. Further, upon reprint operation for multiple order persons, sorting work after the print is facilitated by providing with an identification means for identifying each order person.

The user is continually provided with re-tailored information resulting from an iterative process of obtaining and evaluating data that progresses the user towards a desired behavior modification. The desired behavior modification can be, for example, the cessation of smoking.

A network quality control system includes a user control console to probe, calculate, and display the quality of an enterprise's network connections to remote SNMP managed devices supporting real-time services like VoIP. Traceroute-like messages are sent to each remote SNMP managed device to report on the path, and hop latency, jitter, and packet losses. MOS scores are computed to indicate performance with a variety of available codec's. Empty test packets used simply to probe network quality are not used. Instead, SNMP messages that carry valuable information or commands for other purposes are gleaned of timing information so the MOS quality scores can be calculated in background.

A cloud computing system is described herein that enables fast processing of queries over massive amounts of stored data. The system is characterized by the ability to scan tens of billions of data items and to perform aggregate calculations like counts, sums, and averages in real-time (less than three seconds). Ad hoc queries are supported including grouping, sorting, and filtering without the need to predefine queries by providing highly efficient loading and processing of data items across an arbitrarily large number of processors. The system does not require any fixed schema, thus the system supports any type of data. Calculations made to satisfy a query may be distributed across a large number of processors to parallelize the work. In addition, an optimal blob size for storing multiple serialized data items is determined, and existing blobs that are too large or too small are proactively redistributed or coalesced to increase performance.

A method of processing a document object model (DOM) tree having at least one tag located at a given node in the tree. The tag serves as a marker that initiates the invocation of a tag handler that, in turn, performs a simple macro substitution or a more complex algorithmic reorganization and manipulation of the tree. Upon encountering the tag, given information is passed to a method. In a first embodiment, the given information is a text representation of XML in the DOM tree at the given node and any child nodes of the given node. In an alternate embodiment, the given information is the given node of the DOM tree itself. The method generates an XML string, which is then parsed into a new DOM tree having a root node. The given node and any child nodes are then replaced by the new DOM tree, with the root node of the new DOM tree being positioned at the given node in the original DOM tree. The process may then be repeated for any additional tags.

A data processing apparatus is provided which allows easy identification of a correspondence relationship between a trace packet and a performance packet. The data processing apparatus includes: a measurement trigger generation unit that generates a measurement trigger; a performance monitor unit that measures a performance measurement event collected from a central processing unit (CPU) and outputs a measurement value; and a CPU trace unit that generates a trace packet sequence of trace information including an operation record of the CPU. Upon receipt of the measurement trigger, the performance monitor unit starts or ends measurement of performance metrics or outputs the measurement value, while, upon receipt of the measurement trigger, the CPU trace unit generates a trigger packet indicating generation of the measurement trigger and inserts the trigger packet, at a position corresponding to timing with which the measurement trigger is generated, into the trace packet sequence.
