The article presents an exemplary solution of computation dissipation of luminous flux distribution in interiors, taking into account their multiple reflections, by means of a parallel virtual machine of cluster type. Communication between the processors was ensured by the PVM library operating under the operational system LINUX. Advantages and faults of the programs operating at the computers connected into the network making the cluster are discussed. An analysis of acceleration and efficiency of a concurrent program is carried out. During construction of the algorithm attention was paid to minimization of the number of transferred messages. Calculation examples are presented.
