一种利用并行复算实现的OpenMP 容错机制 总被引:1,自引:0,他引:1
基于并行复算的故障恢复技术,将故障恢复的计算任务分配至未发生故障的结点上并行执行,从而显著缩短复算时间,有效降低故障恢复开销,提高并行程序容错性能.基于该故障恢复技术,提出了一种针对OpenMP并行程序的容错机制PR-OMP,有效解决了分段复算、复算负载重分布等问题;此外,还扩展了传统编译数据流分析技术,提出了针对OpenMP并行程序的数据流分析技术,并基于该技术计算状态保存开销进行优化.设计实现了用于支持PR-OMP的编译工具GiFT-OMP,并通过实验证明了PR-OMP机制及其支持工具的有效性,评估并分析了其性能和可扩展性. 相似文献

Rotary actuation generated by a cyclic symmetric stator vibrations have been investigated in this research by using numerical finite elements. The cyclic symmetric stator’s vibration response is characterized through parameter studies with varying number of protrusion fingers, their geometry parameters and contact angle between stator fingers and rotor. The structure responses on the stator disk and protrusion finger of the stator have been experimentally validated in this study. The split-frequency structure vibration response on the protrusion fingers has been found to be catalogued by the number of the finger on the stator disk. The radial deformation of the protrusion finger was examined and characterized by two different parameters, namely the displacement strength and the bending deformation angle. The numerical studies in this research were validated by experimental mechatronic prototype, from which good agreement between the two and consistency between prediction and measurement were found. 相似文献

This paper proposes a novel concept of using the sharable bandwidth of public-shared network, like FON network, to construct an efficient video delivery system. We show that the problem of constructing an architecture to serve the video streaming requests by using a minimum amount of sharable bandwidth is NP-Hard. A linear approximation algorithm is also proposed to manage the public-shared bandwidth so that all clients are served and the total amount of employed sharable bandwidth is no greater than twice of the optimal solution. 相似文献

In the ATM Forum activities, considerable efforts have focused on the congestion control of point-to-point available bit rate (ABR) service. We present a novel approach that extends existing point-to-point (unicast) congestion control protocols to a point-to-multipoint (multicast) environment. In particular, we establish a unified framework to derive a multicast congestion control protocol for an ABR service from a given rate-based unicast protocol. We generalize a known necessary and sufficient condition on the max-min fairness of unicast rate allocation for a multicast service. Using this condition, we show that the resulting multicast protocol derived using our framework preserves the fairness characteristics of the underlying unicast protocol. The practical significance of our approach is illustrated by extending a standard congestion control mechanism for an ABR service to a multicast environment. The performance of the resulting multicast protocol is examined using benchmark network configurations suggested by the traffic management subworking group at the ATM Forum, and simulation results are presented to substantiate our claims 相似文献
