MigrateAtomsMsg.h

Go to the documentation of this file.

/*
   Migration messages are sent from HomePatch to HomePatch
   with lists of atoms and atom information (if any) that
   need to be migrated.  A message must be sent from a
   neighbor even if null so that the HomePatch knows
   what atoms it will have before commencing a positionsReady()
   to its Computes.
