In light of this this question and some stuff I read online I am wondering if large FE libs (e.g., deal.ii, libmesh etc.) that do AMR keep the entire mesh or possibly a coarse version of the entire mesh on each core. Also, does this limit the size of the problems that can be solved on machines with low RAM per core.

Finally how is load balancing performed? Is the entire mesh repartitioned after each refinement/coarsening step?
