	413	!> Version with one optimized loop over all equations. It is only allowed to

	416	!> Here the calls of most subroutines are embedded in two DO loops over i and j,
	417	!> so communication between CPUs is not allowed (does not make sense) within

	420	!> (Optimized to avoid cache missings, i.e. for Power4/5-architectures.)
