Dynamic Adaptation for Grid Computing

Abstract

As Grid architectures provide resources that uctuate, applications that should be run on such environments must be able to take into account the changes that may occur. This document describes how applications can be built from components that may dynamically adapt themselves. We propose a generic framework to help the developpers of such components. In the case of a component that encapsulates a parallel code, a consistency model for the dynamic adaptation is dened. An implementation of a restricted consistency model allowed us to experiment our ideas.

Dynamically Adapting Software Components for the Grid

A Self-Adaptable Approach for Easing the Development of Grid-Oriented Services

“…In [3], [10], [1], [12] there are further discussions about adaptation techniques. While [1], [12] address general issues and enabling technologies for software adaptation, [3], [10] propose an adaptation design that divides distinct adaptation concerns: Monitor, Analyze, Plan and Execute 2 .…”

On one hand, in [10], the authors propose a general architecture for Autonomic Computing.…”

“…On one hand, in [10], the authors propose a general architecture for Autonomic Computing. On the other hand, Dynaco (Dynamic Adaptation for Components) [3] proposes an adaptation model validated by a framework for developing self-adaptable application on grids. Furthermore, Dynaco promotes the re-usability of adaptation generic mechanisms which can be customized according to the adaptation domain.…”

“…The self-adaptive aspect is addressed by Dynaco (Dynamic Adaptation for Components) [3] in a design based on components. We rely on iPOJO [6] due to its dynamic and flexible capabilities for developing and maintaining services on OSGi [14] platforms.…”
