Note that these are single-precision only, and you have to convert your
complex data into a split format (ctoz()/ztoc()) for the FFT routines.
But they are very fast -- the end really justifies the means.

I am new to this list. I am porting a code to the G5

computing on intel boxes until now am am anxious to
see what my new G5 can do in comparison. I have a
fortran90 code which simulates the motion of the human
vocal folds in phonation. The code uses a
Navier-Stokes solver which assumes periodic bc and
uses fft very efficiently. I want to move to the G5
with the same code intact but with the intel MKL
library replaced with some _optimized_ library for the
G5 containiing, among other things, the fft routines
[I do complex to complex and the inverse and extract
the real part ]. I am hopeful that someone on this
list can point me to a highly optimized fft. I am
aware of fftw, but have not tried it on the G5. Does
anyone know of routines which have these properties
and are sharable.
Thanks much for your help.
