<h4 class="subsection">6.7.3 An improved replacement for MPI_Alltoall</h4>

<p>We close this section by noting that FFTW&rsquo;s MPI transpose routines can
be thought of as a generalization for the <code>MPI_Alltoall</code> function
(albeit only for floating-point types), and in some circumstances can
function as an improved replacement.
