基于QOS的网格用户驱动调度器

QOS based user driven scheduler for grid environment

Sanjay Patel, Madhuri Bhavsar

摘要:

由于网格在本质上是异构的、动态的、共享的和分布式的环境,有效地管理这些平台是非常复杂的。一个有前途的可扩展的方法来处理这些复杂性是设计的自主应用程序的自我管理。自治应用通过考虑自身行为和环境条件的知识来相应地调整其执行。基于QoS的网格用户驱动调度为自治应用提供了自优化能力。计算网格通过在物理位置的多台机器上分散单个大型计算,为用户提供解决大规模问题的能力。基于QoS的用户驱动网格调度器通过应用用户定义的调度策略来减少作业的执行时间,从而提高网格系统的可靠性,提高网格的性能。本文的主要目的是在网格节点之间分配计算负载,并开发一种基于QoS的网格调度算法,使网格更加可靠。网格计算系统不同于传统的分布式计算系统,它强调大规模的资源共享,其中处理器和通信对网格计算的可靠性有重要影响。由最终用户从提交到网格执行的应用程序中启动的可靠性功能。基础设施和管理服务的可靠性,这些服务执行网格系统运行所必需的基本功能,例如资源分配和调度。

英文摘要:

As grids are in essence heterogeneous, dynamic, shared and distributed environments, managing these kinds of platforms efficiently is extremely complex. A promising scalable approach to deal with these intricacies is the design of self-managing of autonomic applications. Autonomic applications adapt their execution accordingly by considering knowledge about their own behaviour and environmental conditions.QoS based User Driven scheduling for grid that provides the self-optimizing ability in autonomic applications. Computational grids to provide a user to solve large scale problem by spreading a single large computation across multiple machines of physical location. QoS based User Driven scheduler for grid also provides reliability of the grid systems and increase the performance of the grid to reducing the execution time of job by applying scheduling policies defined by the user. The main aim of this paper is to distribute the computational load among the available grid nodes and to developed a QoS based scheduling algorithm for grid and making grid more reliable.Grid computing system is different from conventional distributed computing systems by its focus on large scale resource sharing, where processors and communication have significant inuence on Grid computing reliability. Reliability capabilities initiated by end users from within applications they submit to the grid for execution. Reliability of infrastructure and management services that perform essential functions necessary for grid systems to operate, such as resource allocation and scheduling.
