Hi everyone

Does anybody know if one can change the ranks of
process within the world communicator?  As far as
I know the group/communicator management routines
returns a new handle.  Can we somehow pass the world
communicator (MPI_COMM_WORLD) as the target
to any of these routines?  I am interested to know if the
ranks of the processes in MPI_COMM_WORLD can
change in any way?

Thanks in advance
Kamran
