Constrained economics, globalization, competition, alliance, outsourcing, and network economy, all force enterprise IT applications to be reviewed from a new perspective. IT managers are frequently asked if the enterprises already have enough IT capacity; if IT departments should be outsourced; how long will it take to connect our ERP with our partners’ ERPs; if the real-time business process i...

In Virtual organization, Knowledge Discovery (KD) service contains distributed data resources and computing grid nodes. Computational grid is integrated with data grid to form Knowledge Grid, which implements Apriori algorithm for mining association rule on grid network. This paper describes development of parallel and distributed version of Apriori algorithm on Globus Toolkit using Message Pas...

As Grids are emerging as the next generation service-oriented computing platforms, they need to support Grid economy that helps in the management of supply and demand for resources and offers an economic incentive for Grid resource providers. To enable this Grid economy, a market-like Grid environment including an infrastructure that supports the publication of services and their discovery is n...

We are using Web (Grid) service technology to demonstrate the assimilation of multiple distributed data sources (a typical data grid problem) into a major parallel high-performance computing earthquake forecasting code. Such a linkage of Geoinformatics with Geocomplexity demonstrates the value of the Solid Earth Research Virtual Observatory (SERVO) Grid concept, and advance Grid technology by b...

After a brief overview of the elements of modern grid computing, a number of common use-cases of natural language processing tasks running on the grid are presented, notably corpus annotation with morpho-syntactic tagging (600+ million-word corpus in one day), n-gram statistics processing of a corpus and web-accessible services with annotation and term-extraction as examples. Implementation con...

There is increasing recognition of the need for laboratory experience that is through these experiences that students could deepen their understanding of the conceptual material, especially for the science and engineering courses. Virtual Experiment has advantages over physical laboratory at many aspects. Nowadays virtual experiments are mostly stand-alone applications without standard interfac...

Grid computing is concerned with the sharing and coordinated use of diverse resources in dynamic distributed virtual organizations The dynamic nature of Grid environments introduces challenging security concerns that demand new technical approaches In this brief overview we review key Grid security issues and outline the technologies that are being developed to address those issues We focus in ...

Grid resources such as data, services, and equipment, are increasingly being annotated with descriptive metadata that facilitates their discovery and their use in the context of Virtual Organizations (VO). Making such growing body of metadata explicit and available to Grid services is key to the success of the VO paradigm. In this paper we present a model and management architecture for Semanti...

Business process integration can be complex when it spans organisations. Existing grid technology aims to provide the capability to link processing between organisations, but does not presently provide manageable secure access to grid resources. Furthermore, current workflow tools connecting grid services lack security for collaborative workflows. The DAME (Distributed Aircraft Maintenance Envi...

This paper presents a Peer-to-Peer (P2P) infrastructure that supports a large scale grid. The P2P infrastructure is implemented in Java and federates Java Virtual Machines (JVMs) for computation. The management of shared JVMs is decentralized, self-organized, and configurable. The P2P infrastructure was deployed as a permanent desktop grid, with which we have achieved a computation record by so...
