Аннотация:The study of the algorithms parallel structure is becoming increasingly important for any specialists dealing with high-performance computing. Theoretical information on this topic is included in various training courses of many higher educational institutions. However, the usual form of practical training is only the execution of tasks for the parallel implementation of specific algorithms. In the course “Supercomputing Simulation and Technologies” at the Faculty of Computational Mathematics and Cybernetics at Lomonosov Moscow State University, we have proposed a new type of practical task related to the study, description and visualization of the algorithms parallel structure. Using the AlgoView visualization system developed by the authors, the study of the information structure can be carried out without access to high-performance computing systems. The same approach is planned to be used in the AlgoWiki Open encyclopedia of parallel algorithmic features.
