In this paper an attempt is made to create a system for generating the parallel codes to simulate some astrophysical phenomena on modern computing architectures. A code construction scheme for the numerical solution of various problems of the cosmic plasma hydrodynamics is proposed using a knowledge base with an ontological representation of a given mathematical simulation area. The ontology of numerical methods and parallel algorithms and the ontology of parallel architectures and technologies together with the expert (inference) rules allow selecting an efficient numerical method, a parallel algorithm and a computational architecture for solving a necessary problem from the outlined domain. The corresponding program units that implement various stages of solving the problem on a chosen computational architecture are substituted into scheme of solving the problem constructed in this way. Program units can be based on both the author’s implementation and on calling various parallel libraries.
