In this paper we are carried out the computer simulation of the dust cloud dynamics in the radio frequency discharges at the microgravity conditions using PIC/MCC method for electrons and ions and hydrodynamics model for dust particles. The moving of dust particles is governed by the electrostatic force, ion and neutral drag forces, which are averaged over period of RF discharge. The calculations were performed under various gas pressures, densities and radii of dust particles. The obtained results show that dust particles form layer with sharp boundaries in the discharge chamber. Locations of the layer boundaries don"t coincide with the edges of the rf-sheathes and depend on size of dust particles and ion density in discharge. The dust density distribution is almost uniform in the central part of the layer. At the edges of the cloud significant peaks of dust density are formed.
