The trend of grid computing available on the Internet has generated challenges to the allocation of resources provided by this type of environment. Considering the user's satisfaction, many of these challenges can be solved by the quality of experience paradigm that takes into account several context parameters. Considering the resources utilization, the quality of context paradigm can be used to...
An optimal resource allocation is desired to increase the efficiency of systems processing business or scientific workflows. These systems include the processing of workflows in distributed computing environments such as grid or cloud computing. Current approaches used in this systems consider QoS-requirements as quality, speed or costs in the resource allocation process and just select the resources...
Managing virtual machines (VM) in large scale enterprise grid scenarios, commonly encountered in data centers, is extremely challenging. Currently, live VM migration is based on QoS non-conformance events; migration of a VM is initiated as soon as the aggregate resource (CPU and memory) requirements of the VMs on the physical machine (PM) exceed the capacity available on the PM. However, this paper...
Grid resource management plays an important role while enabling the sharing and coordinating of resources in grid computing environments. Resource reservation is an important part of the grid resource management. An advance reservation is a scheduling object which reserves a group of resources for a particular timeframe for access only by a specified entity or group of entities. Combining resource...
QoS requirements of Grid users for Grid service resources always include multiple fuzzy attributes. And there is contradictory between these QoS parameters. A multi-attributes decision making method based on information entropy is utilized to weigh the importance degree of QoS parameters and solve the contradictory. In addition, evaluation factor set is classified according to the type of QoS parameters,...
In this paper, we present a performance analysis of a dynamic bandwidth monitoring method with flow control functionality, for intensive data-passing grid applications over wide area networks. The proposed method called flatness based trajectory tracking, adapts the grid users output rates to match expressive data-transfer SLA used to describe theirs guarantees parameters. The control considers time...
The grid service has been used widely as a trend, and the scheduling algorithm for grid service has become a research focus. In this paper, a grid service scheduling architecture based on economic model (GSAEM) is proposed. The GSAEM introduces economic model into grid service scheduling, and deduces the optimal prices of grid service under every condition of resource constraints by marginal principle...
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...
