Resumen:
A simple way to obtain self-consistent models of triaxial stellar systems  is to follow with an N-body code the collapse of an initial distribution of mass points. To determine the orbital structure of the triaxial systems so obtained one has to resort to codes of different kinds: 1) N-body codes to build up the systems that will be studied; 2) Fit the system´s potential with smooth and constant formulae; 3) Separate regular from chaotic orbits and, within the latter, recognize partially and fully chaotic ones; 4) Classify the regular orbits through frequency analysis. Here we present a description of the codes we have been using for that purpose, as well as some of the results we have recently obtained with them. We give a brief description of the cluster of parallel processors that has begun to operate at La Plata and its possible expansion in the foreseeable future, as well as some examples of its computing speed with those codes.
