194	! step (not at each sub-time step).

447	! Description:
448	! ------------
449	!> Version with one optimized loop over all equations. It is only allowed to
450	!> be called for the Wicker and Skamarock or Piascek-Williams advection scheme.
451	!>
452	!> Here the calls of most subroutines are embedded in two DO loops over i and j,
453	!> so communication between CPUs is not allowed (does not make sense) within
454	!> these loops.
455	!>
456	!> (Optimized to avoid cache missings, i.e. for Power4/5-architectures.)
