abstract = "Recently alternative approaches in cosmology seeks to explain the
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.",
