                         nature of dark matter as a direct result of the non-linear 
                         spacetime curvature due to different types of deformation 
                         potentials. In this context, a key test for this hypothesis is to 
                         examine the effects of deformation on the evolution of large 
                         scales structures. An important requirement for the fine analysis 
                         of this pure gravitational signature (without dark matter 
                         elements) is to characterize the position of a galaxy during its 
                         trajectory to the gravitational collapse of super clusters at low 
                         redshifts. In this context, each element in an gravitational 
                         N-body simulation behaves as a tracer of collapse governed by the 
                         process known as chaotic advection (or lagrangian turbulence). In 
                         order to develop a detailed study of this new approach we develop 
                         the COsmic LAgrangian TUrbulence Simulator (COLATUS) to perform 
                         gravitational N-body simulations based on Compute Unified Device 
                         Architecture (CUDA) for graphics processing units (GPUs). In this 
                         paper we report the first robust results obtained from COLATUS.
