The fundamental problem the Grid research and development community is seeking to solve is how to coordinate distributed resources amongst a dynamic set of individuals and organizations in order to solve a common collaborative goal. The problem of service discovery in a Grid environment arises through the heterogeneity, distribution and sharing of the resources in different virtual organization...

Grid computing boosts productivity by maximizing resource utilization and simplifying access to resources which are shared among virtual organizations. Recently, the Grid and Web Service communities have established a set of common interests and requirements. The latest version of the Globus Toolkit implements the Web Service Resource Framework (WSRF) specifications which have been formulated t...

Grid services exploit an emerging distributed computing technology that offers possibilities for distributed resource sharing and collaboration. The standards for WSRF (Web Service Resource Framework) have allowed grid services to converge more closely on web services. Composing web services has attracted significant effort and commercial interest. This has resulted in BPEL (Business Process Ex...

Grid services have come to represent the synthesis of web services and grid computing paradigms. Web services provide the means to modularize software, enabling loosely coupled and novel synthesis. Grid computing removes the binding between functional software components and specific hosting hardware, enabling software to be deployed dynamically over a network (e.g. intra-, extraor inter-net). ...

In this paper, we present a Workflow-based grId portal for problem Solving Environment(WISE) which has been developed by integrating workflow, Grid and web technology to provide an enhanced powerful approach for problem solving environment. Workflow technology supports coordinated execution of multiple application tasks on Grid resources by enabling users to describe a workflow by composing man...

Data mining is a widely used approach for the transformation of large amounts of data to useful patterns and knowledge. Fuzzy association rules mining is a data mining technique which tries to nd association rules without the e ect of sharp boundary problems when data contains continuous and categorical attributes. Grid data mining is a new concept, which allows the data mining process to be de...

The fundamental problem the Grid research and development community is seeking to solve is how to coordinate distributed resources amongst a dynamic set of individuals and organizations in order to solve a common collaborative goal. The problem of service discovery in a Grid environment arises through the heterogeneity, distribution and sharing of the resources in different virtual organization...

In modern on demand grid computing scenarios, services from different organisations will potentially run on the same web service engine of a grid node. Secure isolation of data and code of different service instances is a vital requirement in such an environment, since mutual trust cannot be assumed between all involved parties. For Java based Grid applications the Java virtual machine offers s...

Subject of this thesis are the design and implementation of an ad hoc Grid infrastructure. The vision of an ad hoc Grid further evolves conventional serviceoriented Grid systems into a more robust, more flexible and more usable environment that is still standards compliant and interoperable with other Grid systems. A lot of work in current Grid middleware systems is focused on providing transpa...

Recent work towards a standard based, service oriented Grid represents the convergence of distributed computing technologies from e-Science and e-Commerce communities. A global service management system in such context is required to achieve efficient resource sharing and collaborative service provisioning. This paper presents VEGA system software, a novel grid platform that combines experience...
