Grid computing architecture was defined to be a complete physical layer. The functions of information systems based on grid architecture are resources sharing, collaborative processing, etc. However, each resource of collaborated grid nodes changes dynamically, how to make these resources optimize plan and allocation is an important issue. In this paper, we proposed a dynamic analyzing resource...

Grid Computing has made substantial advances in the past decade; these are primarily due to the adoption of standardized Grid middleware. However Grid computing has not yet become pervasive because of some barriers that we believe have been caused by the adoption of middleware centric approaches. These barriers include: scant support for major types of applications such as interactive applicati...

The development of the World Wide Web has changed the way that we think about information. Information on the web is distributed, updates are made asynchronously and resources come and go online without centralized control. Global networking will similarly change the way we think about and perform computation. Grid computing refers to computing in a distributed networked environment in which co...

Technological, Finance, Scientific, engineering and other applications and in specific grand challenge applications are becoming ever more demanding in terms of their computing requirements. Gradually, all these requirements can no longer be managed by a single organization. A Cost-effective modern technology that could address the computing bottleneck is grid computing, which enable clusters o...

* This project is supported by High-Tech Programme 863 (2001AA113121) and National Natural Science Foundation of China (90104021). ABSTRACT Establishing grids is an important undertaking in developing scalable distributed infrastructures. In this paper we have proposed a model for agent-based grid computing from the implement point of view. Based on the model agent-based grid computing system A...

In this expository article we will be primarily concerned with core aspects of Grids and Grid computing using OSS with some emphasis on utility computing. It is based on a technical report entitled 'Grid-Computing Using Linux' by the present author. Grids have made great progress in the area of scientific computing and collaboration projects in the recent past. They have also moved into the dom...

In this paper, first we survey security problems which exist in grid computing and then we analyze security requirements. At the end we introduce a framework which Erin Cody has posed as a solution for security problems of grid computing. The framework presented classifies security literature into System Solutions, Behavioral Solutions and Hybrid Solutions.

This paper briefly surveys how authorisation in Grid computing has evolved during the last few years, and presents the latest developments in which Grid applications can utilise a policy controlled authorisation infrastructure to make decisions about which users are allowed to perform which actions on which Grid resources. The paper describes the Global Grid Forum SAML interface for connecting ...
