The last advances in computation have made feasible the resolution of very complex problems. Grid computing has matured to currently become one of the most successful initiatives for dealing with these challenging problems, which usually require tackling huge volumes of data. Although the main goal of the grid technology is sharing resources among several virtual organizations, few research wor...

Grid computing provides a robust paradigm to aggregate disparate resources in a secure and controlled environment. Grid architectures require an underpinning Quality of Service (QoS) support in order to manage complex computationand data-intensive applications. However, QoS guarantees in the Grid context have not been given the importance they merit. In order to enhance the functionality offere...

The effectiveness of modern complex Grid systems strongly depends on the availability, accuracy and relevance of information on all connected resources, their characteristics and state. An access to this information plays a very important role in any Grid system, providing necessary information for other Grid components and users. We set a goal for "intellectualization" of key Grid systems to p...

Information service is one of the key components of the grid system, and information service interoperation is the first step towards grid interoperation. Existing grid interoperability projects mainly focus on immediate bridge mechanisms, which is intricate and of poor scalability. A uniform information service interoperation framework (UISIF) is proposed in the paper, which adopts virtual lay...

Currently there is no practical standard for grid middleware, most of the grid platforms are built by their own, and it’s not easy to interoperate these grid platforms. Information service is one of the key components of the service oriented grid system, and information service interoperation among heterogeneous grids is the first step towards grid interoperation. Existing grid interoperability...

Computational grid systems are becoming popular with the rapid spread of computational environments dealing with large-scale applications in various areas. In general, a grid service needs to use a set of resources to complete certain tasks. Thus, in order to provide a grid service, allocating required resources to the grid is necessary. In order to increase the grid service reliability, optima...

As the emergence of Open Grid Service Architecture (OGSA), service grid is seen as a natural progression from computational grid. Because of the diversity and the complexity of the applications, it is a large challenge for the research on service grid platform. Currently, the popular information service systems are basically used to provide registry, publication, and management for computing re...

Grid service is next-generation computing platform. Transaction for Grid service is one of the key technologies. In heterogeneous, dynamical and autonomous Grid environment, however, traditional transaction technologies is unsuitable. And little attention has been paid to support transaction coordination for Grid service. In this paper, we propose a transaction framework that can coordinate ato...

The paper studies a distributed iterative algorithm for optimal scheduling in grid computing. Grid user’s requirements are formulated as dimensions in a quality of service problem expressed as a market game played by grid resource agents and grid task agents. User benefits resulting from taking decisions regarding each Quality of Service dimension are described by separate utility functions. Th...
