Abstract : 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 ease programming for scientists, maintainability and portability issues are transferred from scientists to DSL de- signers. This paper deals with an approach to improve main- tainability and programming productivity of DSLs through the generation of a component-based parallel runtime. To study it, the paper presents a DSL for multi-stencil pro- grams, that is evaluated on a real-case of shallow water equations.
