In this paper, we present a framework for Shared Memory Architectures that make design of parallel applications easier. We use the Model-Driven Engineering (MDE) approach and integrate new metamodels in Gaspard for each step of the design flow. The targeted model is an OpenMP metamodel, from which we immediately derive a source code in OpenMP Fortran or OpenMP C. This approach based on models allows a better reuse and also gives a better and more hierarchic view of the application so that it can better fit the architecture.
