This subroutine wraps up the output functionality for the code that creates the list of suggested process counts for the linear computation and checks whether those process counts work well for the non-linear calculations as well.
The optional parameter onlyxoryfac (which is a logical) is used to highlight process counts that have been generated using code which looks for the factors of kx*ky rather than kx and ky separately. This is only currently used for layouts that start with x and y (for instance xyles or yxles).
