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： 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： A system including at least one storage node and at least one computation node connected by a switch is described herein. Each storage node has one or more storage units and one or more network interface components, the collective bandwidths of the storage units and the network interface components being proportioned to one another to enable communication to and from other nodes at the collective bandwidth of the storage units. Each computation node has logic configured to make requests of storage nodes, an input/output bus, and one or more network interface components, the bandwidth of the bus and the collective bandwidths of the network interface components being proportioned to one another to enable communication to and from other nodes at the bandwidth of the input/output bus.
