ion, is
transformd by: (i) transforming the <code>n1</code> dimension, which are
local to each process; (ii) transposing to an <code>n1</code> by <code>n0</code>
array, distributed across the <code>n1</code> dimension; (iii) transforming
the <code>n0</code> dimension, which is now local to each process; (iv)
transposing back.

   <p>However, in many applications it is acceptable to compute a
multidimensional DFT whose results are produced in transposed order
(e.g., <code>
