     Therefore, all the approximations that are usually made when using local FFTs with guard cells
     (for problems with multiple boxes) become exact in the case of the periodic, single-box FFT without guard cells.
 
-* ``psatd.hybrid_mpi_decomposition`` (`0` or `1`; default: 0)
-    Whether to use a different MPI decomposition for the particle-grid operations
-    (deposition and gather) and for the PSATD solver. If `1`, the FFT will
-    be performed over MPI groups.
-
-* ``psatd.ngroups_fft`` (`integer`)
-    The number of MPI groups that are created for the FFT, when using the code compiled with a PSATD solver
-    (and only if `hybrid_mpi_decomposition` is `1`).
-    The FFTs are global within one MPI group and use guard cell exchanges in between MPI groups.
-    (If ``ngroups_fft`` is larger than the number of MPI ranks used,
-    than the actual number of MPI ranks is used instead.)
-
 * ``psatd.fftw_plan_measure`` (`0` or `1`)
     Defines whether the parameters of FFTW plans will be initialized by
     measuring and optimizing performance (``FFTW_MEASURE`` mode; activated by default here).
