| || ||To orientate oneself in parallel systems on the market, be able to assess communication and computing possibilities of a particular architecture and to predict the performance of parallel applications. To get acquainted with the most important parallel programming tools (MPI, OpenMP), to learn their practical use and solving problems in parallel.|
| || ||The course covers architecture and programming of parallel systems with functional- and data-parallelism. First the most proliferated symmetrical multiprocessors with shared bus (SMP) and their programming in OpenMP environment are dealt with. Then follows the treatment of interconnection networks, a basic structure for popular networks of workstations and other message-passing systems. Their programming in standardized interface MPI is illustrated with case studies of parallel applications. Data-parallel systems and programming are in the last group.|
|Knowledge and skills required for the course:|
| || ||Von-Neumann computer architecture, computer memory hierarchy, cache memories and their organization, programming in assembly and in C/C++|
|Subject specific learning outcomes and competences:|
| || ||Overview of principles of parallel system design and of interconnection networks, communication techniques and algorithms. Survey of parallelization techniques of fundamental scientific problems, knowledge of parallel programming in MPI and OpenMP.|
|Generic learning outcomes and competences:|
| || ||Knowledge of capabilities and limitations of parallel processing, ability to estimate performance of parallel applications. Language means for process/thread communication and synchronization. Competence in hardware-software platforms for high-performance computing and simulations.|
