MPI FFTW
========

   This section describes the MPI FFTW routines for distributed-memory
(and shared-memory) machines supporting MPI (Message Passing
Interface).  The MPI routines are significantly different from the
ordinary FFTW because the transform data here are *distributed* over
multiple processes, so that each process gets only a portion of the
array.  Currently, multi-dimensional transforms of both real and
complex data, as well as one-dimensional transforms of complex data,
are supported.
