It looks one can subdivide all nodes into
groups. What is the purpose then of
having....
mpi_comm_rank as well as mpi_group_rank???
mpi_comm_size as well as mpi_group_size???
Are groups and comms interchangeable as arguments
to mpi commands???
I thought they were equal but not I'm not sure.
Any help would be greatly appreciated.
Sincerely,
Chris
