<P>(3.d) The FFT_INC variable also allows for a -DFFT_SINGLE setting that
will use single-precision FFTs with PPPM, which can speed-up
long-range calulations, particularly in parallel or on a GPU. Fourier
long-range calulations, particularly in parallel or on GPUs. Fourier
transform and related PPPM operations are somewhat insensitive to
floating point truncation errors and thus do not always need to be
performed in double precision. Using the -DFFT_SINGLE setting trades
