Ghost cells: Cells that are duplicated across multiple machines. For example if we're considering an edge where the end vertices reside on different machines, it's possible we will need access to both vertices. Ghost cells require update messages to be exchanged across machines when writes occur, but not reads.

The Lizst compiler will actually generate MPI sends and receives (for a cluster system) for the ghost cells depending on how it divided up the mesh! That's pretty cool.
