Summary:We represent results of numerical simulation of molecular clouds dynamical collision. The problem was considered in 3D on extremely high resolution computational grids. The choice of so highly detailed grids is necessary due to fulfillment of numerical Jeans instability. The numerical code was parallelized using OpenMP and CUDA. The code uses Automatic Mesh Refinement (AMR) procedure. We discuss the application of the used numerical method for the simulation of molecular clouds fragmentation, formation of proto-cores and filaments formation what is important for the star formation processes.
