A Framework for Desktop GRID Applications: CCADAJ

Abstract : We 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.
