Abstract: Described are various embodiments of a light field vision testing device, adjusted pixel rendering method and computer-readable medium therefor, and vision testing system and method using same. In one embodiment, a device or computer-implemented method is provided to dynamically adjust user perception of an input image to be rendered via a set of digital display pixels and a corresponding array of light field shaping elements until an optimal visual acuity level is identified.

Abstract: A transparent high-availability solution utilizing virtualization technology is presented. A cluster environment and management thereof is implemented through an automated installation and setup procedure resulting in a cluster acting as a single system. The cluster is setup in an isolated virtual machine on each of a number of physical nodes of the system. Customer applications are run within separate application virtual machines on one physical node at a time and are run independently and unaware of their configuration as part of a high-availability cluster. Upon detection of a failure, traffic is rerouted through a redundant node and the application virtual machines are migrated from the failing node to another node using live migration techniques.

Abstract: A system is provided for rapidly synchronizing two or more processing elements in a fault-tolerant computing system. Embodiments of this system allow for the rapid synchronization of two processing elements through partial copies of the contents of memory associate with each processing element.

Abstract: In one general aspect, a network communication unit is disclosed that includes connection servicing logic that is responsive to transport-layer headers and is operative to service virtual, error-free network connections. A programmable parser is responsive to the connection servicing logic and is operative to parse application-level information received by the connection servicing logic for at least a first of the connections. Also included is application processing logic that is responsive to the parser and operative to operate on information received through at least the first of the connections based on parsing results from the parser.
