  • Patent number: 7640278
    Abstract: A partial-blocking consistency point system identifies transaction updates with a consistency point ID associated with a consistency point sequence number, records consistency point data that identify a location of the partial-blocking consistency point, flushes to a non-volatile storage the transaction updates identified with the consistency point sequence number without blocking transaction activity, and hardens to the non-volatile storage the recorded partial-blocking consistency point so that data associated with the recorded partial-blocking consistency point can be recovered. The consistency point sequence number is incremented each time the partial-blocking consistency point is recorded to uniquely identify the partial-blocking consistency point and transaction updates associated with the partial-blocking consistency point. The transaction updates identified with the consistency point sequence number are processed to improve efficiency of the flushing of the transaction updates.

  • Publication number: 20080315052
    Abstract: The invention relates to improvements in hubs for wall mounting systems for screens, and in particular to a hub for a wall mounting system for a flat panel screen, such as a plasma display or television screen, which enables the screen to be tilted. The hub comprises a casing, means for attaching the hub to a screen bracket, means for attaching the hub to an arm of a wall mount, and a tilt member. The tilt member has a sliding member which is located within an arcuate cavity in the casing such that the sliding member and casing are slidable relative to each other to enable a screen attached to the mounting system to be tilted about a horizontal pivot axis. The arc is defined by the cavity having its centre, which forms the pivot axis, offset from the centre of gravity of the screen. The hub further comprises a compression spring located within the casing and biased to provide a counterbalancing force so that the screen remains stationery in any position.

  • Patent number: 7447829
    Abstract: A method and system in accordance with the present invention comprises a thread stack/thread heap combination, wherein the thread heap is for thread local memory usage and wherein the thread stack and thread heap grow in opposite directions. In the present invention the thread specific heap is allocated next to the thread's stack and grows in the opposite direction from that of the stack. This improvement allows the current space management of thread stacks, which spread out the memory placement of multiple stacks to avoid collision, to also be used for the heaps without additional overhead or complexity. It also allows the existing growth scheme of adding memory pages to the process for the stack to be used again because the growth is simply in the opposite direction. Thread specific heaps eliminate the need for expensive synchronization when allocating from a shared heap in a multiprocessor environment.

  • Publication number: 20070220298
    Abstract: A system that provides fault tolerance in a parallel processing system. During operation, the system executes a parallel computing application in parallel across a subset of computing nodes within the parallel processing system. During this process, the system monitors telemetry signals within the parallel processing system. The system analyzes the monitored telemetry signals to determine if the probability that the parallel processing system will fail is increasing. If so, the system increases the frequency at which the parallel computing application is checkpointed, wherein a checkpoint includes the state of the parallel computing application at each computing node within the parallel processing system.

  • Publication number: 20070214394
    Abstract: One embodiment of the present invention provides a system that enhances throughput and fault-tolerance in a parallel-processing system. During operation, the system first receives a task. Next, the system partitions N computing nodes into M set-aside nodes and N-M primary computing nodes, wherein M?1. The system then processes the task in parallel across the N-M primary computing nodes. While doing so, the system proactively monitors the health of each of the N-M primary computing nodes. If the system detects a node in the N-M primary computing nodes to be at risk of failure, the system copies the portion of the task associated with the at-risk node to a subset of the M set-aside nodes. The system then processes the portion of the task in parallel across the subset of the M set-aside nodes while the N-M primary computing nodes continue executing.
