Im Bereich des Grid Computing stehen Workflows im Fokus zahlreicher Projekte. Allein auf europäischer Ebene wurden und werden viele Projekte zur Entwicklung von geeigneten Werkzeugen, Sprachen und Laufzeitumgebungen für Workflows im GridComputing gefördert. Der dritte Grid Workflow Workshop adressiert sowohl wissenschaftliche als auch betriebliche Workflows im Umfeld des Grid-Computing. Diese d...

Through the 1990s to 2012 the internet changed the world of computing drastically. It started its journey with parallel computing after it advanced to distributed computing and further to grid computing. And in present scenario it creates a new world which is pronounced as a Cloud Computing [1]. These all three terms have different meanings. Cloud computing is based on backward computing scheme...

Grid computing and pervasive computing have affirmed respectively as the paradigm for high performance computing and the paradigm for user-friendly computing. The conjunction of such paradigms are now generating a new one: the Pervasive Grid Computing. This paper presents a middleware for pervasive grid applications. It consists of a set of basic services that aim to enhance classic grid enviro...

Grid computing is used to realize the connection of distributed, heterogeneous computing resources through grid, assist in accomplishing computing task. Focusing on the weakness of centralized information fusion, put forward the disturbed fusion model utilizing grid computing node to realize local decision fusion on the basis of distributing information fusion architecture, and transform the de...

The development of ubiquitous computing and mobility opens challenges for implementation of grid computing in ad hoc network environments. In this paper, a new grid computing implementation for ad hoc networks is proposed. The proposed addition of the ad hoc network protocols suite offers an easy and effective way to exploit the computing power of the network nodes. The model is implemented in ...

The Globus Toolkit has been widely used as middleware in Grid computing environments. Java CoG, Web Service and Portlet help to build Grid computing portals easily and productively. Many Grid Portals can provide a customizable interface allowing scientists and researchers to perform Grid operations such as remote submission of their own programs, staging input and ouput files, and querying reso...

Grid Computing allows coordinated and controlled resource sharing and problem solving in multi-institutional, dynamic virtual organizations. Moreover, fault tolerance and task scheduling is an important issue for large scale computational grid because of its unreliable nature of grid resources. Commonly exploited techniques to realize fault tolerance is periodic Checkpointing that periodically ...

Grid computing facilitates the realization of large-scale intraand inter-organization collaborative computer applications by harnessing computing, storage, and networking resources available over the Internet. The concept of grid computing paradigm is analogous to that of electricity power grid where electricity sources are connected together in a grid and consumes’ needs for electricity are ad...

The previous chapter of this thesis describes various aspects of grid computing environment and the security issues associated with grids. In this chapter, we present a detailed survey of relevant literature in grid computing security. The aim of this survey work is to present current research trends from the point of view of the security models and authorization mechanisms available in the gri...

Currently, e-Science applications run on dedicated computing platforms. The scientific/e-Science computing community developed the Grid to share resources and maximize compute capacity available for e-Science applications. Applications exist that incidentally have urgent high demand for compute capacity, for example in case of emergencies. Also, some researches need to do experiments with Grid ...
