Hello, I've read at http://www.fftw.org/fftw3_doc/Usage-of-Multi_002dthreaded-FFTW.html#Usage-of... that getting fftw to use multiple threads to speed up performance on SMP machines is quite easy to initiate. Has anyone used tried this? I haven't ever used fftw without scipy, but if there were some way to easily implement a python interface such that fftw_init_threads(), fftw_plan_with_nthreads(), and fftw_cleanup_threads() could be called, it would be really cool. I'm having a bit of a time trying to figure out how fftpack is married to fftw ... maybe I should just try calling those functions with ctypes? Any input would be greatly appreciated. Thanks, Glen
