Abstract: A virtual machine monitor (VMM) is configured to enforce deterministic execution of virtual machines in a multiprocessor machine. The VMM is configured to ensure that any communication by physical processors via shared memory is deterministic. When such VMMs are implemented in a distributed environment of multiprocessor machines coupled via a logical communication link, non-deterministic server applications running on virtual machines using the VMM may be replicated.

Abstract: This document describes techniques for allowing a computing device that provides a minimal execution environment to execute legacy applications that rely on rich functionality that the computing device does not natively provide. For instance, a device may initially receive a request to execute an application and may determine whether the application is directly executable. In response to determining that the application is not directly executable, the computing device may determine whether the application specifies another application to provide the functionality. If the application specifies another application to provide this functionality, then the computing device retrieves the specified application and executes the specified application on the client computing device. If the application does not specify such an application, then the computing device may execute a default application for providing the functionality. The specified or default application then executes the application that is not directly executable on the minimal-execution-environment computing device.
Abstract translation: 本文档描述了允许提供最小执行环境的计算设备执行依赖计算设备本身不提供的丰富功能的旧应用程序的技术。 例如，设备可以初始地接收执行应用的请求，并且可以确定应用是否可直接执行。 响应于确定应用程序不是可直接执行的，计算设备可以确定应用程序是否指定另一个应用程序来提供功能。 如果应用程序指定另一个应用程序来提供此功能，则计算设备将检索指定的应用程序并在客户端计算设备上执行指定的应用程序。 如果应用程序没有指定这样的应用程序，则计算设备可以执行用于提供功能的默认应用程序。 指定或默认应用程序然后执行在最小执行环境计算设备上不能直接执行的应用程序。

Abstract: 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.

Abstract: Digital maps can be composed of a series of image tiles that are selected based on the context of the map to be presented. Independently hosted tiles can comprise additional details that can be added to the map. A manifest can be created that describes the layers of map details composed of such independently hosted tiles. Externally referable mechanisms can, based on the manifest and map context, select tiles, from among the independently hosted tiles, that correspond to map tiles being displayed to a user. Subsequently, the mechanisms can instruct a browser, as specified in the manifest, to combine the map tiles and the independently hosted tiles to generate a more detailed map. Alternatively, customized mechanisms can generate map detail tiles in real-time, based on an exported map context. Also, controls instantiated by the browser can render three-dimensional images based on the combined map tiles.

Abstract: 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.

Abstract: Techniques for facilitating secure application interoperation via user interface (UI) gestures in computing devices that strictly isolate applications operating thereon are described herein. For instance, applications may define one or more specific UI gestures that, when executed by the user, express that the user desires for the computing device to allow for an instance of directed, ephemeral, by-value communication between two isolated applications. In some implementations, the gesture is an atomic gesture, such as a drag-and-drop operation. That is, the gesture is one that the user completes continuously and without interruption.

Abstract: 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.

Abstract: 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.

Abstract: The described implementations relate to efficient scheduling of transactions and tasks. A memory location, address, or variable previously accessed by a blocked entity is observed periodically to determine an appropriate time to wake and retry the blocked entity. If the previous accessed memory location, address or variable changes state, a scheduler wakes the blocked entity and the blocked entity retries processing. A doubly-indexed data structure of blocked entities and memory locations associated with the blocked entities may be used to efficiently determine when a retrying execution would be profitable.
Abstract translation: 所描述的实现涉及事务和任务的有效调度。 周期性地观察先前被阻塞实体访问的存储器位置，地址或变量，以确定唤醒并重试被阻塞实体的适当时间。 如果先前访问的存储器位置，地址或变量改变状态，则调度器唤醒被阻止的实体，并且被阻止的实体重试处理。 被阻止的实体和与被阻止的实体相关联的存储器位置的双重索引的数据结构可以用于有效地确定重试执行何时是有利可图的。
