摘要： A speculative web browser engine may enable providing transmission of content between a server and a client prior to a user-initiated request for the content hidden in imperative code (event handlers), which may reduce user-perceived latency when the user initiates the imperative code. In some aspects, a speculative browser state may be created from an actual browser state and used to run the event handlers. The event handlers may be modified to direct actions of the event handler to update the speculative browser state. Speculative content may be transmitted between the server and the client in response to an execution of the modified code. The speculative content may be stored in a cache and made readily available for use when the user initiates the event handler and finds that the desired content has already been fetched.
摘要翻译：推测性网络浏览器引擎可以在用户发起对隐藏在命令性代码（事件处理程序）中的内容的请求之前，在服务器和客户端之间提供内容的传输，这可能在用户启动命令性代码时减少用户感知的等待时间。在某些方面，可以从实际浏览器状态创建推测浏览器状态，并用于运行事件处理程序。可以修改事件处理程序来引导事件处理程序的动作来更新推测浏览器状态。响应于修改的代码的执行，可以在服务器和客户端之间传送推测内容。推测内容可以存储在高速缓存中，并且当用户启动事件处理程序并且发现已经获取了所需的内容时，容易可用。

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： 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： 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： Dynamically replicated memory is usable to allocate new memory space from failed memory pages by pairing compatible failed memory pages to reuse otherwise unusable failed memory pages. Dynamically replicating memory involves detecting and recording memory faults, reclaiming failed memory pages for later use, recovering from detected memory faults, and scheduling access to replicated memory pages.

摘要： An illustrative operating system distributes two or more instances of the operating system over heterogeneous platforms of a computing device. The instances of the operating system work together to provide single-kernel semantics to present a common operating system abstraction to application modules. The heterogeneous platforms may include co-processors that use different instruction set architectures and/or functionality, different NUMA domains, etc. Further, the operating system allows application modules to transparently access components using a local communication path and a remote communication path. Further, the operating system includes a policy manager module that determines the placement of components based on affinity values associated with interaction relations between components. The affinity values express the sensitivity of the interaction relations to a relative location of the components.

摘要： A metadata server configured to maintain storage assignment mappings in non-persistent storage is described herein. The tract storage assignment mappings associate servers with storage assignments, the storage assignments representing the data stored on the servers. Responsive to a failure, the metadata server receives the storage assignments from the servers and rebuilds the storage assignment mappings from the storage assignments. The metadata server is also configured to enable clients to operate during a recovery process for a failed server by providing the storage assignment mappings to the clients during the recovery process. Also during the recovery process, the replacement server for the failed server conditionally overwrites stored data with other data received from other servers as part of the recovery process. The replacement server conditionally overwrites based on version information associated with the data and version information associated with the other data, the version information being associated with one or more versions of the storage assignment mappings.

摘要： Field programmable gate arrays can be used as a shared programmable co-processor resource in a general purpose computing system. Components of an FPGA are isolated to protect the FPGA and data transferred between the FPGA and other components of the computer system. Transferred data can be digitally signed by the FPGA or other component to provide authentication. Code for programming the FPGA can be encrypted and signed by the author, loaded into the FPGA in an encrypted state, and then decrypted and authenticated by the FPGA itself, before programming the FPGA with the code. This code can be used to change the cryptographic operations performed in the FPGA, including keys, or decryption and encryption algorithms, or both.

摘要： Field programmable gate arrays can be used as a shared programmable co-processor resource in a general purpose computing system. An FPGA can be programmed to perform functions, which in turn can be associated with one or more processes. With multiple processes, the FPGA can be shared, and a process is assigned to at least one portion of the FPGA during a time slot in which to access the FPGA. Programs written in a hardware description language for programming the FPGA are made available as a hardware library. The operating system manages allocating the FPGA resources to processes, programming the FPGA in accordance with the functions to be performed by the processes using the FPGA, and scheduling use of the FPGA by these processes.
