    摘要： A memory management system is described herein that receives information from applications describing how memory is being used and that allows an application host to exert more control over application requests for using memory. The system provides an application memory management application-programming interface (API) that allows the application to specify more information about memory allocations that is helpful for managing memory later. The system also provides an ability to statically and/or dynamically analyze legacy applications to give applications that are not modified to work with the system some ability to participate in more effective memory management. The system provides application host changes to leverage the information provided by applications and to manage memory more effectively using the information and hooks into the application's use of memory. Thus, the system provides a new model for managing memory that improves application host behavior and allows applications to use computing resources more efficiently.

    摘要： A storage placement system is described herein that uses an operating system's knowledge related to how data is being used on a computing device to more effectively communicate with and manage flash-based storage devices. Cold data that is not frequently used can be differentiated from hot data clusters and placed in worn areas, while hot data that is frequently used can be kept readily accessible. By clustering hot data together and cold data in separate sections, the system is better able to perform wear leveling and prolong the usefulness of the flash medium. Storage of data in the cloud or other storage can intelligently persist data in a location for a short time before coalescing data to write in a block. Thus, the system leverages the operating system's knowledge of how data has been and will be used to place data on flash-based storage devices in an efficient way.

    摘要： A multimedia testing system is described herein that uses a virtual hardware driver to test software application behavior using virtual hardware in place of physical hardware devices. The virtual hardware driver receives customized input patterns that emulate behavior and formatting of data from a wide variety of hardware devices. For webcams, the system can send a steady stream of frames like those that would be provided as output from a physical webcam. A test environment can observe software interaction with the received customized input patterns to determine how the software will interact with various physical hardware devices. Thus, the multimedia testing system allows automated testing of a software application that interacts with multimedia hardware without physically buying and installing hardware devices.

    摘要： A power context system is described herein that makes decisions related to device power usage based on factors such as location, load, available alternatives, cost of power, and cost of bandwidth. The system incorporates contextual knowledge about the situation in which a device is being used. Using the context of location, devices can make smarter decisions about deciding which processes to migrate to the cloud, load balancing between applications, and switching to power saving modes depending on how far the user is from a power source. As the cloud becomes more frequently used, load balancing by utilizing distributed data warehouses to move processes to different locations in the world depending on factors such as accessibility, locales, and cost of electricity are considerations for power management. Power management of mobile devices is becoming important as integration with the cloud yields expectations of devices being able to reliably access and persist data.

    摘要： A kernel trace system is described that acts as a kernel driver to insert traces into an open system kernel using existing kernel probe application-programming interfaces (APIs) and copies these events to an existing logging module for transfer to user space. The new module aggregates kernel traces to a performance logging module. A performance logging module can be extended with the kernel trace system herein to include new events in an open kernel not originally included in the implementation of the performance logging module. In this way, the kernel trace system can cause events to be logged that were not logged in the kernel as provided by the operating system vendor, and can do so without requiring that a new version of the operating system be built. The probes can be inserted dynamically at run time on an existing kernel to extract additional trace information.
