Is it possible to call cufft library calls in device function?

Question

I use the cuFFT library calls in a host code they work fine, but I want to call the cuFFT library from a kernel. Earlier versions of the CUDA didn't have this kind of support but with the dynamic parallelism is this possible ?

It will be great if there are any examples on how to achieve this.

Answer 1

Despite the introduction of dynamic parallelism on Kepler (cc 3.5) cards, cuFFT remains a host API and there is currently no way of creating or executing FFT operations in device code using cuFFT.
