Popis: This paper presents the results of modeling the interaction of a relativistic jet with an inhomogeneous galactic medium. To numerically solve the equations of special relativistic hydrodynamics, a new numerical method was developed combining the Godunov method, flow calculation by the Rusanov method, and piecewise linear representation of the solution. The numerical method was implemented in program code for supercomputer architectures with distributed memory using MPI. The results of studying the code performance on the Intel Broadwell computing nodes of the NKS-1P cluster located in the Siberian Supercomputer Center are presented.
