MKL FFTW interface performance

MKL FFTW interface performance


   I am trying to reproduce the results of the MKL FFTW interface in this report:

   Does anybody know where I can get the source code used in that report?

   So far, I have been running the source code in this webpage:

but the MKL FFTW interface shows really poor performance. I wonder if there is something I am missing.

The MKL performance charts show the performance of other FFT problems than that measured by the benchmark code from Heiko's page.
In particular, the MKL charts show performance of a single transform, while the benchmark runs FFTs of 2 or 4 interwoven data sets. Genuine FFTW is good at such layouts.

A good starting place for benchmarking FFTs is
