I am pretty sure that the overhead of communicating a large array from one process to another will vastly overwhelm any speed gains you get by using pyFFTW over numpy.fft. > To be honest I don't know yet if the FFTs are going to be the limiting step but I thought I may as well give pyFFTW a try and ran into that issue... In that case, thinking about multiprocessing or even pyFFTW is far too premature. Implement your code with numpy.fft and see what performance you actually get. -- Robert Kern
