  abstract	= {Significantly improving the scalability of large
		  structured adaptive mesh refinement (SAMR) applications is
		  challenging. It requires sophisticated capabilities for
		  using the underlying parallel computer's resources in the
		  most efficient way. This is non-trivial, since the basic
		  conditions for how to allocate the resources change
		  dramatically during run-time due to the dynamics inherent
		  in these applications.
		  
		  This report presents a first characterization of a hybrid
		  and dynamic partitioner for parallel SAMR applications.
		  Specifically, we determine optimal parameter settings for
		  trade-offs like communication vs.\ load balance and speed
		  vs.\ quality. The key contribution is that the
		  characterization enables the partitioner to respond
		  accurately to stimuli from system and application state,
		  and hence adapting to various SAMR scenarios. This
		  potentially reduces run-time for large SAMR applications.}
