Lecture Concepts and Models of Parallel and Data-centric Programming†
The traditional simulation is increasingly enhanced by modeling based on (large) data sets. Methods and tools of parallel programming foster the setup, evaluation and adoption of compute-intensive and complex models. In parallel processing of large amounts of data, novel programming models offer additional functionality and performance improvements by adopting data-centric approaches instead of focusing on computations. In this lecture, corresponding programming models, selected algorithms and tools are presented which are used in high-performance computing and data sciences.
The objectives of the lecture are the classification of parallel systems in high-performance computing, as well as the processing of large data sets (big data) and the understanding of optimization and parallelization concepts to exploit these systems. This includes the knowledge and comprehension of the implementation of various programming models, of selected parallel algorithms and respective complexity characteristics and scalability limits.
