In this paper, we perform a comparison of two approaches for the parallelization of an existing, free software, FullSWOF 2D (http://www. univ-orleans.fr/mapmo/soft/FullSWOF/ that solves shallow water equations for applications in hydrology) based on a domain decomposition strategy. The first approach is based on the classical MPI library while the second(More)
GIS processing of large sets of geo-referenced tiles is usually very time-consuming for users. These computations rarely take benefits of PC clusters or Grid computing and are too often run onto simple desktop PC. This is mainly due to the difficulty of parallel programming. In this paper we propose an easy way to greatly accelerate this process for the(More)
High performance architectures evolve continuously to be more powerful. Such architectures also usually become more difficult to use efficiently. As a scientist is not a low level and high performance programming expert, Domain Specific Languages (DSLs) are a promising solution to automatically and efficiently write high performance codes. However, if DSLs(More)
