Abstract: We present a parallel procedure which allows us to speed up the modelling of photometric and spectroscopic observations of active binary stars with brightness inhomogeneities on their surfaces. The procedure has been implemented using PVM and is suitable to run on a cluster of non-homogeneous, non-dedicated computers. It is optimized to recognize and assign the data sets requiring the largest computational effort to the most powerful CPUs of the cluster, taking into account the evolution of their performances during the calculation in a fully dynamical way. We report on several tests made with the workstation cluster of Catania Astrophysical Observatory and discuss the advantages of this kind of procedure for data analysis in Astrophysics.
