A Framework for Desktop GRID Applications: CCADAJ

Abstract

International audienceWe propose a new component framework over a middleware platform for GRID computing: DG-ADAJ (Desktop GRID - Adaptive Distributed Application in Java). Our platform allows to have a Single System Image (SSI) of the GRID platform. It gives a specialmechanism at middleware level which assures dynamic and automatic adaptation to variations of computation methods and execution platform. DG-ADAJ gives also specific mechanisms based on control components which helps a users to build component-based parallel/distributed applications. We use the CCA (Common Component Architecture) as a component architecture model for our framework. CCADAJ (CCA-ADAJ) is a layer above the DG-ADAJ environment, which helps user to build his parallel/distributed applications by assembling components in a transparent way and which exploits the parallelism of the environment

Webservices oriented data mining in knowledge architecture

“…This solution is a completely Java compliant system built around the object oriented programming environment. As shown also in the previously mentioned figures, we have introduced a Common Component Architecture (CCA) based framework [3,5] over the DG-ADAJ platform [4] in order to easily build and deploy applications on the DG-ADAJ platform.…”

“…The DG-ADAJ environment could thus be freed of some of the placement, distribution and execution tasks, by moving significant parts of these to the higher layer of the ESB and enactment environment. With WODKA, the powerful ability to create component-based applications, developed over the DG-ADAJ platform (see [4,12]) is extended with the help of webservices open standards, by offering the possibility to access both local and remote CCA components, eventually deployed on different DG-ADAJ environments.…”

“…In the DisDaMin project (Distributed Data Mining, see [13]), we have introduced solutions for some data mining problems by providing new distributed algorithms suited to a Grid environment. The DG-ADAJ project [4,12] provides a middleware platform for the Grid that can be used as a basis for the deployment of DisDaMin algorithms.…”
