摘要： A system including a plurality of servers, a client, and a metadata server is described herein. The servers each store tracts of data, a plurality of the tracts comprising a byte sequence and being distributed among the plurality of servers. To locate the tracts, the metadata server generates a table that is used by the client to identify servers associated with the tracts, enabling the client to provide requests to the servers. The metadata server also enables recovery in the event of a server failure. Further, the servers construct tables of tract identifiers and locations to use in responding to the client requests.

摘要： A client device configured to write to both a growth server and a live server replica that the growth server is replacing during a growth phase is described herein. The client device first determines the growth server designated to replace a corresponding live server replica of a set of server replicas associated with a storage index. The client device then transmits a write request associated with the storage index to the set of server replicas and to the growth server. The client device may perform the determining based on storage assignment mappings. The storage assignment mappings are provided to the client device by a metadata server while the growth server retrieves data associated with the storage index from the live server replica.

摘要： The claimed subject matter provides a system and/or a method that facilitates optimally and efficiently utilizing an image file format. A server can host an image that is partitioned into two or more tiles, wherein the two or more tiles collectively represent the image in entirety and are defined in at least one image file format. A tile generator can evaluate at least one tile to identify a suitable image file format based upon at least one of a characteristic of such file format or a context of a use for the tile. A browser can utilize the tile in the identified file format in order to render a portion of the image.

摘要： The creation of an effective circuit between a sender device and a receiver device over the packet-switched network is described herein. To establish the effective circuit, the sender device sends a request to the receiver device through the packet-switched network. The request is associated with a bandwidth reservation from the receiver device for reception of a message from the sender device. The receiver device receives multiple requests from multiple sender devices and reserves bandwidth for at least one of the sender devices. The receiver device then sends a response to the at least one sender device providing clearance to send the message to the receiver device using the reserved bandwidth, the request and response establishing the effective circuit. The receiver device may also decline the requests of the other sender devices, causing the other sender devices to send other requests to other receiver devices.

摘要： The subject disclosure is directed towards one or more parallel storage components for parallelizing block-level input/output associated with remote file data. Based upon a mapping scheme, the file data is partitioned into a plurality of blocks in which each may be equal in size. A translator component of the parallel storage may determine a mapping between the plurality of blocks and a plurality of storage nodes such that at least a portion of the plurality of blocks is accessible in parallel. Such a mapping, for example, may place each block in a different storage node allowing the plurality of blocks to be retrieved simultaneously and in its entirety.

摘要： A system is disclosed that transforms offline maps into interactive online maps. In the system, geo-coordinate relationships are determined between geo-coordinates on a source map and geo-coordinates on an online reference map. An image of the source map is transformed to form an image of a modified source map having geo-coordinates that substantially align with corresponding geo-coordinates on the reference map. Modified source tiles are formed with the image of the modified source map and displayed on a portion of the reference map.

摘要： Techniques for enabling client computing devices to leverage remote server pools for increasing the effectiveness of applications stored on the client computing device are described herein. In some instances, the server pools comprise a “cloud”, “cluster” or “data center” that comprises hundreds or thousands of servers connected together by a network that has an extremely low latency and high bandwidth relative to the network through which the client computing device connects to the server pool. The client computing device may request that the server pool perform a certain task for an application whose canonical state resides on the client. After computation of a result of the task, a server of the server pool then provides the result to the client. By doing so, the techniques dramatically increase the amount of resources working on the request of the client and, hence, dramatically increase the speed and effectiveness of the client-side application.

摘要： Techniques for leveraging legacy code to deploy native-code desktop applications over a network (e.g., the Web) are described herein. These techniques include executing an application written in native code within a memory region that hardware of a computing device enforces. For instance, page-protection hardware (e.g., a memory management unit) or segmentation hardware may protect this region of memory in which the application executes. The techniques may also provide a narrow system call interface out of this memory region by dynamically enforcing system calls made by the application. Furthermore, these techniques may enable a browser of the computing device to function as an operating system for the native-code application. These techniques thus allow for execution of native-code applications on a browser of a computing device and, hence, over the Web in a resource-efficient manner and without sacrificing security of the computing device.
