Grid computing is a state-of-the-art parallel computing technology which enables the worldwide computers to dynamically share their computing powers and resources to each other. The driving forces for the grid and some key challenges of grid computing are discussed in this paper. This paper also presents a service oriented grid computing model which emphasizes that grid is a special computing s...

One of the key challenges for a “Grid programmer” today is how to expose functionality as an OGSIcompliant Grid Service. One of the principle differences between programming a Grid Service and simply coding the service logic is that a certain amount of meta-data is needed to actually expose that service logic as a grid service. This meta-data consists of instructions to the service’s hosting en...

This paper investigates grid computing from the point of view three basic computing platforms. Each platform considered consists of virtual compute resources, a programming environment allowing for the development of grid applications, and a grid operating system to execute user programs and to make solving complex user problems easier. Three platforms are discussed: compute grid, metacompute g...

Grid Geospatial Information Service (Grid GIS) system aims to study and develop grid-based uniform spatial information access and analysis system. Data resources of Grid GIS include not only original and traditional GIS data but remotely sensed data. Analysis function is made up of not only single spatial information access but complex and quick data processing. The Grid GIS system can provide ...

The development of modern science requires the equipment grid to provide a scientific collaboration research platform, which can realize remote collaboration and sharing with the key instruments and equipment in wide areas. The reliability and high efficiency of a grid service chain model are key points in creation of a grid equipment system. The π-calculus as powerful process algebra has a spe...

Earlier work in the areas of Service-Oriented Architecture (SOA) and Grid computing resulted in the Open Grid Services Infrastructure (OGSI) specification, which defined Grid services as an extension of Web services. As a result, people often try to understand the relationship between Grid and Web services or even compare between them. This paper clarifies that, with the on-going developments i...

This paper presents initial results of investigating and developing grid-enabled tools for collaborative image processing, visualisation, and database access within the context of the mouse atlas project at the MRC Human Genetics Unit. OGSI compliant grid services for compute intensive task in the mouse atlas have been investigated and a grid service has been developed to implement a grid-enabl...

Grid computing provides key infrastructure for distributed problem solving in dynamic virtual organizations. It has been adopted by many scientific projects, and industrial interest is rising rapidly. Compared with traditional single computer system, effective service locating in Grid is difficult because of huge amount and wide-area distribution of dynamical services. This paper presents a new...

National geological survey works have characteristics of data enormousness, computing denseness, resource distribution, and applications heterogeneousness. As innovative information infrastructure and service architecture, grid can meet geological survey application requirements by implementing sharing and cooperation of distributed and heterogeneous resources. Based on grid technologies and OG...

With the rapid development of Internet, Grid becomes more and more popular. In this paper, mobile service is introduced to solve some key problems in Grid environment, such as load balance and fault tolerance etc. A mobile service is the combination of Grid service and mobile agent and has migration ability that can make it migrate between grids and ability to detect surroundings to decide when...
