It is shown how to handle the various aspects related to the performing and managing of a typical N-body simulation. For this purpose, the features and usage of one of the parallel codes available in AstroComp, namely the ``treeATD'' code,

The main motivation of the AstroComp project is to construct a portal, which allows to set up a repository of computational codes and common databases, making them available and enjoyable, with a user-friendly graphical web interface, to the

Their shapes are compared among themselves quantitatively. A striking similarity suggests the hypothesis that all the different kinds of astrophysical objects considered were formed by essentially the same process. Theoretical mass functions, based on the hypothesis of fragmentation due to gravitational instability (Di Fazio, 1985), are compared with the observations, yielding a remarkably good agreement.

Aim of these simulations is to understand whether the merging of a group of globular clusters in a unique stellar system
