Abstract
The emergence of generic interfaces, encapsulating algorithmic aspects in pattern-based constructions, has greatly alleviated the development of data-intensive and stream-processing applications. In this paper, we complement the basic patterns supported by GrPPI, a C++ General and Reusable Parallel Pattern Interface of the state-of-the-art, with the advanced parallel patterns Pool, Windowed-Farm, and Stream-Iterator. This collection of advanced patterns is basically oriented to some domain-specific applications, ranging from the evolutionary to the real-time computing areas, where compositions of basic patterns are not capable of fully mimicking algorithmic behavior of their original sequential codes. The experimental evaluation of the advanced patterns on a set of domain-specific use-cases, using different back-ends (C++ Threads, OpenMP and Intel TBB) and pattern-specific parameters, reports remarkable performance gains. We also demonstrate the benefits of the GrPPI pattern interface from the usability and flexibility points of view.
