Service Level Agreements provide the foundation to negotiate for a distinct Quality of Service level between the provider and the consumer of a service. Since the Grid community is adopting concepts of Service-Oriented Architectures and Web Services are capturing their space within the Grid landscape, resource management within Grids increasingly evolves towards the management of resources repr...

The Grid has emerged as a new distributed computing infrastructure for advanced science and engineering aiming at enabling sharing of resources and information towards coordinated problem solving in dynamic environments. Research in Grid Computing and Web Services has recently converged in what is known as the Web Service Resource Framework. While Web Service technologies and standards such as ...

Today grid middleware is complex to be used, the development of grid-aware applications is errorprone and the Virtual Organization grid paradigm contrasts with traditional HPC optimisation strategies based on resource stability and known cost models of inter-node interaction patterns. The authors analyse several aspects of grid adaptivity, and identify 5 roles: the active resource/execution man...

This work proposes p-Learning grid, a service-oriented approach, based on a pervasive learning grid, for solving difficulties associated with the sharing of learning resources distributed on different e-Learning platforms. The p-Learning grid not only enables collaboration and effective reuse of learning objects but also supports learning anytime, anywhere. Since the WSDL of web services remain...

Background: A cursory analysis of the biomedical grid literature shows that most projects emphasize data sharing and the development of new applications for the grid environment. Much less is known about the best practices for the migration of existing analytical tools into the grid environment. Objectives: To make GeneHunter available as a grid service and to evaluate the effort and best pract...

The Grid Information Service (GIS) is one of the Grid Common Services which make up the basic functions belonging to Grids. This service offers a resource discovery mechanism, of which an implementation is provided by the Monitoring and Discovery Service (MDS-2), which is part of the Globus Toolkitw. Grid applications are typically the users of this resource discovery mechanism; knowledge is th...

This position paper addresses the question of integrating GRID and MAS (Multi-Agent Systems) models by means of a service oriented approach. Service Oriented Computing (SOC) tries to address many challenges in the world of computing with services. The concept of service is clearly at the intersection of GRID and MAS and their integration allows to address one of these key challenges: the implem...

Many Grid applications require high bandwidth end-to-end connections between Grid resources in different domains. Fiber optic networks, owned by different providers, have to cooperate in a coordinated manner in order to provide an end-to-end connection. Currently, multi-domain optical network solutions require paper-based long-term contracts between administrative domains. This paper describes ...

Grid computing brings heterogeneity and decentralization to the world of science and technology. It leverages every bit of idle computing resources andprovides a straightforwardmiddleware for integrating cross-domain scientific devices and legacy systems. In a super big Grid, job scheduling is challenging specifically when it needs to have access to vast amount of resources. The process of mapp...

We propose the use of programmable Grid resource partitioning heuristics in the context of a distributed service Grid management architecture. The architecture is capable of performing automated and exclusive resource-to-service assignations based on Grid resource status/properties and monitored service demand. We present two distinct approaches for the partitioning problem, the first based on ...
