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

472	!> Version with one optimized loop over all equations. It is only allowed to
473	!> be called for the Wicker and Skamarock or Piascek-Williams advection scheme.
474	!>
475	!> Here the calls of most subroutines are embedded in two DO loops over i and j,
476	!> so communication between CPUs is not allowed (does not make sense) within
477	!> these loops.
478	!>
479	!> (Optimized to avoid cache missings, i.e. for Power4/5-architectures.)
