[lammps-users] difference between comm and reverse_com

Dear Steve and LAMMPS users,

Could you explaine what is the difference between comm_compute and
Which of them I should use to get atom-tag information about ghost atoms?

Doese global numeration of atom exist?
Does ghost atom numeration in list->firstneigh correspond to global
numeration of atoms?

Maybe you recomend some published papers.

Sincerely Yours,
Alexander Vorontsov

Forward comm sends info from real atoms to ghost atoms.
Reverse comm does the inverse. Ghost atoms already
have atom-tag info, so you shouldn't need to do it again.
Atoms do have a global ID. Indices stored in neighbor
lists are local indices, not global.
