Hello Everyone,

Suppose I want to use a 2-dimensional cartesian topology and I want to
broadcast to a given row or column.  Is there a direct, easy way of
creating appropriate communicators for the rows and columns from the
cartesian communicator?  Ot should I just use MPI_Group_incl and list
the processes one by one for each row and column I need?

Thanks,
