In the grid environment, some of the nodes may be working while others may not be active. Alternatively, all the computers could be operational, but their interconnection network may fail. From the perspective of one computer, such network partitioning may appear as a failure to other computers. These types of failures may lead to a major impact on the whole application, which is executing on the Grid for many days. In this paper we will be meta-modelling the computational grid and implementing the fault tolerant mechanism using Java agents. The purpose of the work proposed in this paper is to automate the development of a computational grid and creating graphical workflows of applications using domain-specific modelling techniques. This paper is to provide a high level view for the construction of Grid applications with the flexibility in design and deployment. Copyright © 2013 Inderscience Enterprises Ltd.

Implementation of the fault tolerance in computational grid using agents by meta-modelling approach

International Journal of Communication Networks and Distributed Systems

Applying fault detection and correction techniques in a context become a complicated issue in an environment like computational grid. Agent technology promises a more flexible approach, easier installation and management of the agent framework, and better ability to autonomously recover from failures. Understanding and handling failures becomes additional burden for application developers in a distributed environment. So tolerating the faults and maintaining the performance of the grid becomes a major challenge in the grid computing environment. The work was aimed at building a fault tolerant computational grid using agent-based scheduler. It was found that agent technology offers many advantages in terms of ease of deployment, usage and the ability to control the scheduling of grid applications at a higher level. The framework provided a generic mechanism for incorporating agents into grid applications. It was applied to the meta-scheduler with multi criteria approach. This work also does performance evaluation of the proposed approach with respect to make span time and average scheduling time of each job.
