  We present our studies on jet-induced modifications of the characteristic of
the bulk nuclear matter. To describe such a matter, we use efficient
relativistic hydrodynamic simulations in (3+1) dimensions employing the
Graphics Processing Unit (GPU) in the parallel programming framework. We use
Cartesian coordinates in the calculations to ensure a high spatial resolution
that is constant throughout the evolution of the system. We show our results on
how jets modify the hydrodynamics fields and discuss the implications.
