The paper presents examples of solutions of computation dissipation of luminous flux distribution in interiors, taking into account multiple reflections, carried out at a parallel machine of cluster type. The structure of homogeneous and heterogeneous cluster was discussed. For communication between the processes the PVM library was used, operating under the LINUX operational system. Advantages and faults of the programs operating at the computers connected into the cluster are discussed. Acceleration and performance of the concurrent program was analyzed. In designing the algorithm attention was paid to minimization of the volume of interchanged messages. In the case of the heterogeneous machine three algorithms were compared each other. Examples of calculation results are presented, operation modes of homogeneous and heterogeneous clusters are compared.
