Grid computing involves the coordination of multiple distributed processes such that they function as one system. Computational Grids are used to achieve this. Grid computing operates through the use of remote machines accepting executable code, which they process. Grid computing defines far more than the organisation and architecture of computational networks. How Grid is used, the policies un...

Grid Infrastructure and popular Grid computing toolkit Globus Toolkit 3.0(GT3) are introduced in this paper. A distributed simulation system based on Grid computing is developed, working mechanism and architecture model of this system are also discussed in this paper. Simultaneously, a distributed simulation experimentation about lightning electromagnetic field is implemented in Grid computing ...

Grid computing system is different from conventional distributed computing systems by its focus on large-scale resource sharing, where processors and communication have significant influence on grid computing reliability. Most previous research on conventional small-scale distributed systems ignored the communication time and processing time when studying the distributed program reliability, wh...

Grid users always expect to meet some challenges to employ Grid resources, such as customized computing environment and QoS support. In this paper, we propose a new methodology for Grid computing – to use virtual machines as computing resources and provide Virtual Distributed Environments (VDE) for Grid users. It is declared that employing virtual environment for Grid computing can bring variou...

—Grid computing has attracted many researchers over a few years, and as a result many new protocols have emerged and also evolved since its inception a decade ago. Grid protocols play major role in implementing services that facilitate coordinated resource sharing across diverse organizations. In this paper, we provide comprehensive coverage of different core Grid protocols that can be used in ...

Experiences with three practical meteorological applications with different characteristics are used to highlight the core computer science aspects and applicability of distributed computing to meteorology. Presenting Cloud and Grid computing this paper shows use case scenarios fitting a wide range of meteorological applications from 5 operational to research studies. The paper concludes that d...

In a basic grid computing system, every computer can access the resources of every other computer belonging to the network. In the ideal grid computing system, every resource is shared, turning a computer network into a powerful supercomputer. It’s a special kind of distributed computing. In distributed computing, different computers within the same network share one or more resources. Cloud co...

Grid computing technologies enable widespread sharing and coordinated us of networked resources, including computing resources. Open Grid Service Architecture (OGSA) marries Web services to grid protocols, thereby making progress in defining interfaces for grid services. We put forward here a hierarchical architecture, which is based on grid service, for parallel computing in grid environment. ...
