Abstract: An original kinetic model for the molecular velocity distribution function is considered. Based on this model, the equations of ideal magnetogasdynamics (MGD) are derived and an original model for dissipative MGD is obtained. The latter model can be used to construct algorithms easily adaptable to high-performance computer architectures. As an example, results of high-performance computations of astrophysical phenomena are presented, namely, the formation of cosmic jets is modeled.

Key words: magnetogasdynamics, kinetic models, kinetically consistent algorithms, high-performance computations.
