Query: The holographic dual of a Riemann problem in a large number of
  dimensions   We study properties of a non equilibrium steady state generated when two heat
baths are initially in contact with one another. The dynamics of the system we
study are governed by holographic duality in a large number of dimensions. We
discuss the "phase diagram" associated with the steady state; the dual,
dynamical, black hole description of this problem; and its relation to the
fluid/gravity correspondence.
