Parallel programming is hard. To make it a little bit easier, various computation models and technologies are developed. However in turn they are complicated itself, making it harder to add useful features to them. One way to reduce software complexity is a modular approach, for example plugin-based. It allows to add features into software in a structured way. In this paper, a plugin-based approach is suggested to be used in the author-developed technology for parallel computing, the Parallel Programming Kit (PPK).
