Grid Computing is about sharing of the resources and provides the facility to access the shared resources by allocation, virtualization and management. To utilize the heterogeneous resources, resource provisioning and scheduling is required. Resources can be effectively provisioned on the basis of QoS parameters. Further scheduling of resources can be done based on provisioned resources. In this paper,...
Business oriented grids call for effective Quality of Service strategies able to adapt to different user requirements. Performance analyses and predictions with respect to different load conditions or management policies are essential instruments to define such strategies. In this paper, we present a non-Markovian Stochastic Petri Net model that allows to conduct performance analyses of Grid systems...
The provision of Quality of Service in Grid environments is still an open issue that needs attention from the research community. One way of contributing to the provision QoS in Grids is by performing meta-scheduling of jobs in advance, that is, jobs are scheduled some time before they are actually executed. In this way, the aproppriate resources will be available to run the job when needed, so that...
Grid systems allow the execution of a class of highly demanding services and applications. These grids involve communication networks, and their links are essential resources for massive data transfers. However, the management of current grid systems requires intervention for efficient service provisioning. Moreover, this need increases with the increase in demand for grid services. Therefore, grid...
Based on the analysis of grid computing characteristics, this paper brings up an enterprise grid architecture, analyses the functionality of consisted modules and focuses on session scheduling algorithm of workload management layer. Via analyzing the disadvantages of traditional priority-based FCFS scheduling strategy, this paper makes two ameliorations of the strategy- dynamic priority-based proportional...
With the continuous deepening of the network technology and application , there is strict requirements inequality of service (QoS) to the grid, how to reasonable allocation resources so that the maximum utilization of the resources becomes a press for solution based on users in meeting the requirements of QoS. In this paper to the dynamic,distributing and isomerism of grid resources a QoS-based dynamic...
The grid system should present the heterogeneous, distributed resources with different qualities and availabilities as a coherent, coordinated system. This article suggests a new and somewhat complete architecture for resource management. This system provides conditions like advance reservation, the control of accessibility authentication, migration form a resource to another, and deadlock discovery...
In order to co-ordinate multiple resource providers in grid environment to meet a common objective, support for negotiation is needed to establish a contract between the user and the resource providers that clearly states the QoS required, restrictions on resource utilization and penalties during violation of the objective. Strength of the negotiation process mainly depends on the selection of resources...
As Grid networks grows, the complexity of resource management in Grid networks dramatically increases. To manage the Grid resources efficiently, policy based resource management system is suitable. However, the policy which made at a moment could not be appropriate to other time because the condition of the grid resources with time space changes. Thus, in this paper, we propose asynchronous policy-based...
