Enabling Transparent Data Sharing in Component Models

Abstract

The fast growth of high-bandwidth unde-area networks has encouraged the development of computational grids. To deal with the increasing complexity of grid applications, the software component technology seems very appealing since it emphasizes software composition and re-use. However, current software component models only support explicit data transfers between components. The distributed shared memory paradigm has demonstrated its utility by enabling a transparent access to data via a globally shared data space. This paper proposes to extend software component models with shared memory capabilities, enabling tmnsparent access to shared data across components and leading to further decreased software complexity.
