Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Implementations of a file system that is supported by a non-volatile memory that is directly connected to a memory bus, and placed side by side with a dynamic random access memory (DRAM), are described.
