Query: Ensuring domain consistency in an adaptive framework with distributed
  topology for fluid flow simulations   Top-tier parallel computing clusters continue to accumulate more and more
computational power with more and better CPUs and Networks. This allows,
especially for environmental simulations, computations with larger domain sizes
and better resolution. One of the challenges becoming increasingly important is
the decomposition and distribution of the overall work load. State-of-the-art
parallel codes usually use solutions that involve complete knowledge of the
domain topology, which will lead to communication and memory bottlenecks when
computing very large domains. To meet this challenge, the authors propose a new
strategy for decentralised domain management, based on a proven hierarchic data
structure. On the way of developing a framework where individual sub-domains
only have local knowledge of their surroundings, this contribution describes
the communication patterns used in ensuring a consistent domain, without the
need for expensive global broadcast messages. Furthermore, the routines
necessary to deal with adaptive changes in domain topology, due to refinement,
coarsening and migration of sub-domains to different computational resources,
are discussed in detail.
