Development of the instrumental support of the domestic computing platform "Elbrus 801-PC" in the problems of neural network modeling of nonlinear dynamic systems

The development of tools for solving research problems with the use of domestic software and hardware is an urgent direction. Such tasks include the tasks of neural network modeling of nonlinear controlled systems. The paper provides an extended analysis of the capabilities of the Elbrus architecture and the blocks of the built-in EML library for mathematical modeling of nonlinear systems. A comparative analysis of the instrumentation and efficiency of computational experiments is performed, taking into account the use of an 8-core processor and the potential capabilities of a 16-core processor. The specifics of the EML library blocks in relation to solving specific types of scientific problems is considered and the optimized software is analyzed. The design of generalized models of nonlinear systems with switching is proposed. For generalized models, a new switching algorithm has been developed that can be adapted to the Elbrus computing platform. An algorithmic tree is constructed, and algorithmic and software are developed for the study of models with switching. The results of adaptation of the modules of the software package for modeling managed systems to the elements of the platform are presented. The results of computer modeling of nonlinear systems based on the Elbrus 801-RS computing platform are systematized and generalized. The results can be used in problems of creating algorithmic and software for solving research modeling problems, in problems of synthesis and analysis of models of controlled technical systems with switching modes of operation, as well as in problems of neural network modeling and machine learning.
