Scientific simulations give rise to complex codes where data size and computation time become very important issues and sometimes a scientific barrier. Therefore, aiding parallelization has become a main topic in computer science. In this paper is introduced a new type of solution to give a totally transparent access to parallel programming for noncomputer(More)
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)
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)
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)
