Summary:This paper describes how to improve separation between domain-specific code and parallel code in skeletal systems. Traditionally, the code used to exploit parallelism is tangled among domain-specific code, which leads to problems such as: poor maintainability, lower flexibility, and weak scalability. In this paper we introduce the design of the YaSkel framework, which is a support tool to write parallel programs. We argue that the design of YaSkel framework allows more freedom to change the parallelization strategy when compared with traditional skeleton frameworks. To change the parallelization strategy we rely on DI - Dependency Injection - to inject a reference of a specific skeleton in latter development stages. We also show that AOP - Aspect Oriented Programming - could be used to minimize the impact of applying skeleton based approaches to legacy code.
