    摘要： A computing system for determining performance factors for using in performance modeling of a deployed subject system, is presented. The computing system includes a plurality of software components comprising the subject system. Each of the components is susceptible to event tracing while executing on the computing system. The computing system includes a tracing component. The tracing component is configured to trace events of the components of the subject system as they execute. The computing system includes a transaction identification table. The transaction identification table comprises starting and ending actions for transactions performed by the subject system. The computing system also includes a transaction identification component that identifies actions from traced events, identifies related actions corresponding to a transaction according to the starting and ending actions in the transaction identification table, and stores the related actions in the transaction workflow data store.

    摘要： A method and system are presented for determining the loading and capacity on a variable capacity channel by measuring the times at which packets are enqueued for transmission, and have their transmission completed, or by measuring these times in addition to the arrival times of the packets. The times may be measured using a device driver or other operating system component. The measurement may be performed in a centralized or distributed fashion for multi-access or point to point channels.

    摘要： A method and system for avoiding network congestion by measuring network load to adjust a rate at each source. The load (e.g., as a price value) is provided to network traffic sources, which adjust their flows based on a per-flow weight (willingness to pay). The load may be determined in-band by routers or out-of-band by an observer node. A load value (e.g., as a price) is increased or decreased based on the actual load or an estimate based on the actual load. The sources obtain the load value and control the output rates per flow based on each flow's associated weight (willingness to pay), e.g., as set by an administrator. Further, two classes of applications are enabled by allowing certain applications to ignore price.

    摘要： A data transfer system is described herein that allows data to be sent directly between two computing devices at the request of a third party client computer. The system allows a third party to initiate data transfers between computers in a network file system. This results in a significant speed increase because little to no data travels over the third party's potentially slower connection. The data transfer system provides a mechanism to determine if the direct transfer would be more efficient than two separate read and write operations, based on measurements of bandwidth and latency between each computing device. The data transfer system provides support for the source server to compress the data and the destination server to decompress the data at the direction of a third party client to further save network bandwidth.

    摘要翻译： 本文描述了允许在第三方客户端计算机的请求下在两个计算设备之间直接发送数据的数据传送系统。 系统允许第三方在网络文件系统中的计算机之间启动数据传输。 这导致显着的速度增加，因为几乎没有数据传播通过第三方的潜在较慢的连接。 基于每个计算设备之间的带宽和延迟的测量，数据传输系统提供了一种机制，以确定直接传输是否比两个单独的读取和写入操作更有效。 数据传输系统提供对源服务器的压缩数据和目的服务器的支持，以在第三方客户端的方向解压缩数据，以进一步节省网络带宽。

    摘要： A secure location system is described herein that leverages location-based services and hardware to make access decisions. Many mobile computers have location devices, such as GPS. They also have a trusted platform module (TPM) or other security device. Currently GPS location data is made directly accessible to untrusted application code using a simple protocol. The secure location system provides a secure mechanism whereby the GPS location of a computer at a specific time can be certified by the operating system kernel and TPM. The secure location system logs user activity with a label indicating the geographic location of the computing device at the time of the activity. The secure location system can provide a difficult to forge, time-stamped location through a combination of kernel-mode GPS access and TPM security hardware. Thus, the secure location system incorporates secure location information into authorization and other operating system decisions.

    摘要： A personal datacenter system is described herein that provides a framework for leveraging multiple heterogeneous computers in a dynamically changing environment together as an ad-hoc cluster for performing parallel processing of various tasks. A home environment is much more heterogeneous and dynamic than a typical datacenter, and typical datacenter scheduling strategies do not work well for these types of small clusters. Machines in a home are likely to be powered on and off, be removed and taken elsewhere, and be connected by an ad-hoc network topology with a mix of wired and wireless technologies. The personal data center system provides components to overcome these differences. The system identifies a dynamically available set of machines, characterizes their performance, discovers the network topology, and monitors the available communications bandwidth between machines. This information is then used to compute an efficient execution plan for data-parallel and/or High Performance Computing (HPC)-style applications.
