Abstract : Today's scientific applications, such as natural phenomena simulations, require high computing power and a large storage capacity. The computational grids appear as a solution to offer this power by pooling resources from different organizations. However, these architectures make programming complex: they are dynamic, heterogeneous and widely distributed. This thesis focuses on issues related to the design of a grid data sharing service. The objective is to enable transparent access to data by handling location, transfer and management of fault-tolerance and consistency. We are particularly focused on the management of consistency and persistence in dynamic environment. In this context, ensuring the persistence requires fault tolerance mechanisms. We propose an approach to jointly manage these two aspects through a software architecture that couples various consistency protocols with fault-tolerance mechanisms. We propose a hierarchical design of this architecture, adapted to the grid network topology. These contributions have been implemented in the JUXMEM grid data sharing service. Experiments conducted on the experimental grid Grid5000 show that our hierarchical approach can improve the performance of shared data access.
