摘要： A distributed file system for devices is described. In an embodiment, each data element stored on one of the devices has an associated location and availability attribute. The location attribute is stored co-located with the data element. The availability attribute and a copy of the location attribute are stored by a metadata service. When a client on a device needs to access a data element, it sends a request to the metadata service to find the location of the data element. If the data element is available, this information is provided to the client and this may involve waking a dormant device which holds the data element. Where the data element is not available, read only access may be granted to a cached copy of the data element. Where replication is used and one of the devices holding a replica is unavailable, the system may use write off-loading.

摘要： A data store including a file location attribute is described. In an embodiment, the location attribute for a data element, such as a file or database record, is stored with the bytes of data and records the geographic location of the data element. Writing to this attribute is limited to a single trusted entity, such as an operating system, to ensure that the location data can be trusted and when a data element is moved or replicated, the attribute is updated to reflect the new location of the data element. This location data is made available to users and applications by a metadata service which tracks the locations of data elements and responds to requests from users. Access control policies can been defined in terms of location and stored at the metadata service and the metadata service can then enforce these policies when responding to requests.

摘要： A resource allocation framework for wireless/wired networks is described. In an embodiment, methods of end host based traffic management are described which operate separately from the underlying access control protocol within the network (e.g. wireless MAC protocol or TCP). The rate limits for each flow are set based on per-flow weights, which may be user specified, and based on an estimate of the utilization of the shared resource and the rate limits are adjusted periodically so that the resource is not underutilized or saturated. Some embodiments compute a virtual capacity of the resource which is adjusted to optimize the value of the utilization and then the virtual capacity is shared between flows according to the per-flow weights. Methods for estimating the utilization of a wireless network and the capacity of a broadband access link are also described.

摘要： A user interface for an information retrieval system is described. In an embodiment an output region for showing retrieved documents is displayed on an interactive surface. One or more movable user interface items, such as digital buttons or tangible objects, may be positioned in an active region. Each movable user interface item has a stored query associated with it and for example, the queries may be words or images. In an embodiment a user interface controller apparatus identifies any movable user interface items in the active region and identifies a spatial relationship between those items and the output region. In an embodiment, a query is accessed for each of the user interface items in the active region and those queries and the information about the spatial relationship are used to retrieve documents from a document database.

摘要： A method and system of resource allocation for execution of a job are provided. The method includes receiving feedback (134) regarding the execution of previously submitted jobs on one or more resource nodes (101-104), and estimating the resources required for execution of a submitted job based on the feedback (134) and the parameters of the job. One, or a plurality of resource nodes in parallel, having the estimated resources are allocated the job. The feedback may be implicit feedback indicating the success or failure of the execution of a job. The one or more resource nodes (101-104) allocated for execution of a job may have less than a user requested resource allocation for the job.

摘要： Aspects of a distributed computing environment with remote data collection management include a management server, and a plurality of computer systems networked to and managed by the management server. Each of the plurality of computer systems includes a listening agent to receive process code from a management server and to control the periodic execution of the process code to collect data from the plurality of computer systems. The periodic execution occurs without requiring a connection to be maintained between the plurality of computer systems and the management server. Further, the data collected includes data collected from problem determination activities.

摘要： A method and system for ordering and aggregating log streams. Log streams for events from different sources are received. If different sources have different recording cycles, or time epochs, that lead to different temporal granularities, then all of the log streams are combined into a single time epoch that is equal to the longest time epoch. Log streams from sources having shorter time epochs continue to retain information about their original time epochs, in order to retain information about the order of the events in those log streams. The log streams are re-ordered, both before and after being integrated into the aggregate log, by acquiring additional data from the different sources, thus permitting the likely cause/effect relationship between events.
