e., focus is not on details of a low-level implementation Performance Exploitation of generic parallel execution patterns in a domain at high abstraction level Reduced (restricted) expressiveness Full extraction of available parallelism Make use of knowledge (domain, architecture) for static and dynamic optimizations Portability and Scalability DSL and run-time system should be easily extendable in order to adapt to new architectures Applications (DSL codes) should remain the same Allows hardware engineers to introduce innovations without worrying about portability 4Ħ Goals of a DSL Domain-specific: provide only expressions relevant to the topic Orthogonal: one single way of specifying something Expressive and compact: describe relevant constructs with few statements Abstract: work on a high-level point of view Adaptable: support complex things Adoptable: employ terms and concepts of the domain Regular: all terms should follow the same syntax and ideas Well-defined: non-ambiguous and easy to understand Talk about what should be computed, not how.

Software development has to address all these issues! 1ģ Challenge: The 3 P s Performance Portable: high performance on different target hardware Competetive: performance comparable to hand-written code Portability Support different target architectures from the same algorithm description Support different target languages and technologies from the same algorithm description Productivity Algorithm description at a high level Hide low-level details from the user 2Ĥ Domain-Specific Language (DSL) Definitions Domain-Specific Languages: An Annotated Bibliography, Arie van Deursen, Paul Klint, und Joost Visser: A domain-specific language (DSL) is a programming language or executable specification language that offers, through appropriate notations and abstractions, expressive power focused on, and usually restricted to, a particular problem domain.
