MPI_COMM_SPAWN broken because nextcid_nb not implemented #5

Closed abouteiller closed 6 years ago

Original report by Aurelien Bouteiller (Bitbucket: abouteiller, GitHub: abouteiller).

The algorithm implemented in nextcid and nextcid_nb are different. That makes the cid decision inconsistent and makes in turn MPI_COMM_SPAWN crash because the communicators do not get a unique cid.
