Detailed Description

ER is the abstraction of shuffile and redset into a single interface, SCR and VeloC use both and er to simplify the rebuilding steps. On a restart, shuffile is used to first move files back to owning ranks, depending on new rank-to-node mapping. Then redset is used to rebuild missing files after the shuffle.
