摘要

批量同步并行(BSP)模型对于开发可扩展的并行计算软件非常有用。为了使BSP模型适应网格环境,提出了基于Globus Toolkit服务的BSP开发库BSP- g。本文在BSP-G的基础上,提出了一种agent辅助的ServiceBSP模型。该模型中的代理可以对计算服务进行qos感知选择,并监控这些服务的状态。在选择阶段,代理可以通过引用服务质量本体存储库来处理服务的QoS信息的多样性。实验表明,该agent可以根据QoS需求选择网格服务,为用户提供满意的超步骤

Agent Assisted ServiceBSP Model in Grids
The bulk synchronous parallelism (BSP) model is useful in developing scalable software for parallel computation. To adapt the BSP model to the grid environment, the BSP-G, a BSP development library based on the services of Globus Toolkit has been proposed. In this paper, we further the work of BSP-G and introduce an agent assisted ServiceBSP model. The agent in this model could make a QoS-aware selection of computational services and monitor the status of those services. During the selection phase, the agent can handle the diversity of QoS information of services by referring to an ontology repository of quality of service (QoS). An experiment shows that the agent could provide users with satisfied supersteps by selecting Grid services on QoS demand
