  The divisible sandpile model is a fixed-energy continuous counterpart of the
Abelian sandpile model. We start with a random initial configuration and
redistribute mass deterministically. Under certain conditions the sandpile will
stabilize. The associated odometer function describes the amount of mass
emitted from each vertex during stabilization. In this survey we describe
recent scaling limit results of the odometer function depending on different
initial configurations and redistribution rules. Moreover we review connections
to the obstacle problem from potential theory, including the connection between
odometers and limiting shapes of growth models such as iDLA. Finally we state
some open problems.
