[SciPy-user] parallel usage of fftw

[Glen W. Mabey]

Hello,

I've read at

http://www.fftw.org/fftw3_doc/Usage-of-Multi_002dthreaded-FFTW.html#Usage-of-Multi_002dthreaded-FFTW

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
