  The slip of a fluid layer in contact with a solid confining surface is
investigated for different temperatures and densities using molecular dynamic
simulations. We show that for an anomalous water-like fluid the slip goes as
follows: for low levels of shear, the defect slip appears and is related with
the particle exchange between the fluid layers; at high levels of shear, the
global slip occurs and is related to the homogeneous distribution of the fluid
in the confining surfaces. The oscillations in the transition velocity from the
defect to the global slip is shown to be associated with changes in the
layering distribution in the anomalous fluid.
