How to Structure Parallel Applications: Local Nested Aggregates

摘要: Parallel programming, due to the lack of structuring discipline specially for communications, suffers problem large acceptance: only a complete disciplined approach can help in making process building efficient and reusable parallel programs. The paper presents Local Nested Aggregate (LNA) approach: LNAs are general-purpose entities. Each LNA is externally entity with one input stream output stream. An composed internal parts, their turn, that communicate between themselves accord defined patterns: an entire application consists decomposed top-down fashion. resulting programming style intrinsically disciplined: suggest static order predefine communication pattern. be implemented concretely within different languages: describes possible mapping object language PO.
