In computational grid computing, grid nodes spanning over several diverse computing resources belonging to heterogeneous administrative domains form the backbone of Virtual Enterprise [VE]. In order to offer service-on-demand, various service providers, requesters, brokers and administrators collaborate in request-response manner among each other in Service Oriented Virtual Enterprise through s...

In order to deploy existing scientific or business applications on a service-based Grid, these legacy code programs have to be transformed into Grid services. GEMLCA (Grid Execution Management for Legacy Code Architecture) represents a solution to make available and execute legacy applications through an OGSI Grid service without re-engineering the original code. GEMLCA is a client front-end OG...

This investigation proposed a service-oriented approach based on a pervasive learning grid for solving the difficulties associated with sharing learning resources distributed on different e-Learning platforms. Furthermore, the p-Learning grid not only enabled collaboration and effective reuse of the learning objects, but also supported learning at anytime and anywhere. Since the WSDL of web ser...

This contribution presents the design and implementation of a bank service, constituting a key component in a recently developed Grid accounting system solution. The Grid accounting system maintains a Grid-wide view of the resources consumed by members of a virtual organization. The bank is designed as an online service, managing the accounts of VO projects. Each service request is transparentl...

The grid is moving from the scientific grid to a pervasive and economic/business grid. Service trading, in which service provider and service consumer negotiate for a mutually acceptable agreement on multi-issues such as service performance, access cost etc., is one of the most important components in building the Economic Grid. In view of Pervasive Grid, a new challenging issue is that partici...

In BIS-Grid, a BMBF-funded project in the context of the German D-Grid initiative (http://www.d-grid.de), we focus on employing Grid technologies for information systems integration. The goal is to enable small and medium enterprises (SMEs) to integrate heterogeneous business information systems and to use external Grid resources and services with reasonable effort. To achieve this goal, we dev...

We have developed the ZENTURIO experiment management system for performance studies, parameter studies, and software testing of parallel applications on cluster and Grid architectures. In this paper we describe the design and implementation of ZENTURIO as a Web service-based distributed architecture. We highlight limitations of Web services for deployment on the Grid and propose solutions. Expe...

Database oriented data grid becomes a new demand with the development of grid technology, and DS_Grid (DatabaSe oriented Data Grid) is such a grid system supporting dynamic data integration with the idea of service. In DS_Grid, MultiChord is adopted as the grid framework implementing the distributed storage, processing and data integration of data service resources and the domain and its corres...

Grid service is defined by OGSA as a web service that provides a set of well-defined interfaces and that follows specific conventions. To classify different Grid services and describe their relations, we present Grid Service SemiGroup (GSSG) based on group theory. Moreover, a novel concept, i.e. meta-service, is proposed based on the definition of generating element in cyclic monoid. To meet in...
