Hej
I am new to tbb and trying out some stuff using tbb. is there some good implementation of fast-fourier-transform using tbb available? Thanks anyway

Doesn't seem like it. I guess you could either run FFT on multiple objects using a parallel_for or a parallel_for_each, or write your own algorithm using TBB that does FFT on a single object. After looking here, I found that there have been algorithms for the FFTW library in other parallel technologies, like Cilk, MPI, and just basic threads. Maybe you could convert those!

EDIT: Typo.
EDIT 2: Hey wait, they've written parallel FFT for other parallel technologies...
