Developing FFT's in parallel using Fortran 90

Angel_Vergara — Thu, 05 Nov 2009 16:51:16 GMT

Hi everyone!!!

I'm working in fortran 90 and I need to paralelize the FFT's routines, someone could tell me where can I find some examples or documentation about it??

thanks

Angel

Have you got chance to check MKL DFTI interface? The sample code is located at MKL installation folder examplesdftfsource

Thanks,
Chao

Angel,
as an additional info, I'd recommend to look at the KB article to shows different parallelization techniques for MKL FFT: "http://software.intel.com/en-us/articles/different-parallelization-techniques-and-intel-mkl-fft/"

Why doesn't this article recommend the mkl_sequential library for the cases where threading is to be controlled outside MKL?

Yes, the user can either use the sequential MKL libs or set MKL_SERIAL to YES when he/she uses multithreaded MKL libs and the threading is done outside MKL. We will update the article soon.

Thanks,
