 Parameter to switch on parallel execution of fft and transpositions (with {{{MPI_ALLTOALL}}}).\\\\
 If the fft-Poisson-solver is used (see [#psolver psolver]), '''transpose_compute_overlap''' = ''.T.'' causes the fft to be executed in parallel to the transposition (done by {{{MPI_ALLTOALL}}}). For larger grids, this method may speed up the fft-solver significantly.
