New parallel algorithm is developed for simulating dynamics of thin circumstellar disk. It is based on the combination of gridless method of smoothed particle hydrodynamics (SPH) and grid-based convolution method for calculating gravitational potential. To develop the algorithm we made software profiling of numerical experiments aimed to simulate gravitational fragmentation and subsequent inward migration of dense clumps onto the star.
