Job scheduling is an influential component of Grid computing. Grid consists of large number of heterogeneous resources for solving large scale problems in the area of engineering and research discipline. So a proper job scheduling mechanism is essential for the efficient and reliable working of Grid because if a job is submitted to an inappropriate resource then it will increase the completion time...
As Grid technologies evolve quickly on Internet, research related to resource scheduling faces new opportunities and challenges. These new technologies, ideas and approaches provide a new environment for researching and developing the economy-based resource scheduling system. Aiming at the hierarchical Grid model, following utility optimization thinking, while an universal flexible utility function...
A grid system is a set of independent computers that enables sharing, selection and aggregation of resources for application programs. In such system, computers and resources are distributed geographically. Once the resources are expanded in terms of hardware, software, etc., there is a need to a grid that responds to various requests more quickly. In this study, we present the idea of resource grouping...
Resources allocation is complex undertaking problem in distributed resources share problems. In this work, we consider the problem of engineering agents that act as proxies for the procurement of computational and data resources. By using economic models, mechanisms such as auctions may appropriate for the management of these problems. In this paper, we provide the design and theoretical analysis...
The management of the large scale heterogeneous resources is a critical issue in grid computing. The resource management system (RMS) is an essential component of grids. To ensure the QoS of the upper layer service, it raises high requirement for the performance, fault-tolerance and scalability of RMS. In this paper, we study three typical structures of RMS, including centralized, hierarchical and...
The convergence between Web services and grid computing became possible the integration of distributed services, providing the use of sharing and coordinated resources on the network. In this environment, the purpose of a Metascheduler would improve the performance, availability and scalability of the resources. In this paper, we present a Metascheduler framework aiming QoS provision in Web services...
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...
This paper describes the distributed resource management for QoS driven for CAD-Grid integrated system. In this work, system actualization mode, architecture and function module are discussed in building a distributed QoS driven for CAD-Grid system. An emphasis has been placed on making the tools interactive, in an effort to create a user friendly environment. The goal is to provide an efficient and...
This paper deals with the problem of scheduling workflow applications with quality of service (QoS) constraints, comprising real-time and interactivity constraints, over a service-oriented grid network. A novel approach is proposed, in which high-level advance reservations, supporting flexible start and end time, are combined with low-level soft real-time scheduling, allowing for the concurrent deployment...
Whereas Grids enable the sharing, selection, query and aggregation of geographically distributed resources for solving large-scale problems, providing efficient resource allocation mechanism managing Grid resources is a complex undertaking. In this work, we consider the problem of engineering agents that act as proxies for the procurement of computational and data resources. Since applications may...
With the converging of grid computing and Web service, grid has extended its territory from traditional computing grid to service-oriented grid, which is aiming to realize coordinated resource sharing and problem solving through service selection and composition. Therefore, selecting credible services for applications becomes a key issue in grid environment. Current research on trust inherits the...
As the key character of grid is the good service quality, the study of QoS (quality of services) becomes more and more important. And SLA (service level agreement) can really guarantee the QoS. Although SLA has been a topic in the field of telecom for many years, the researches of it in the grid are still not perfect, especially in the emerging grid economy field. In this paper, we propose a SLA control...
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 role of multimedia application in our life has dramatically increased in the last few years. Multimedia streaming is more significant than downloading ways in multimedia applications from bandwidth and delay reasons. Multimedia contents are in nature distributed in nodes of grid. Streaming media are still not well resolved in grid environment. This thesis proposes an agent-based framework for...
Resource management is one of the basic and key aspects in grid computing, especially in resource allocation and scheduling, which need to be adaptive to handle dynamic changes in availability of resources and user requirements. At the same time, they need to provide scalable, controllable, measurable, and easily enforceable policies for management of resources. In the different types of requirements...
Heterogeneous grid workflow management plays an important role in the grid interoperation. It integrates service resources from different grid systems and packs them as atomic services into a composite service. The focuses of the research are how to shield the difference among the heterogeneous grid services and how to provide a flexible way to compose services. Heterogeneous grid workflow management...
Picture archiving and communications system (PACS) is widely used in hospitals to take medical images, to send images to radiologists or doctors and to store images into storage in a digital manner, that has brought high efficiency in a medical process. Recently, PACS is required to evolve into a more sophisticated system that can communicate with other medical systems. The existing PACS was designed...
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...
As QoS-based resource management is becoming increasingly hot, the research on grid QoS plays a fundamental role in service-oriented grid environment. Grid QoS is classified into five categories in virtual organization layer in our early research. In this paper, we propose a kind of scheme to measure grid QoS based on this classification. In the scheme, the grid QoS parameters are quantified respectively...
In recent years, the technology of grid is developed quickly, but it has to face some problems waiting for resolution, such as improving the real time of grid. And at present the researches focus on two related efforts, the development of protocols enabling negotiation for the QoS of resource use, and the development of resource management pertinence strategies and algorithms. Considering the requests...
