[QE-developers] DFTI and OpenMP detection in configure

[Lorenzo Paulatto]

Hello,
I have noticed that the configure script detects and enables 
automatically the DFTI FFT libraries when executed without any specific 
switch, but that it uses FFTW instead when executed with the 
--enable-openmp switch.

I was wondering if this is intentional (i.e. because FFTW can give 
better performance with openmp? Or DFTI does not work with openmp?) or 
it is a bug.

cheers
