Different result of MKL FFT between version 11.1.067 and 11.1.054

Hello,

I've been using MKL 2D-FFT integrated in a Visual Studio 2005 with a Fortran Compiler version 11.1.067 wiith the following commands:

!For a matrix A(N1,N2)

L(1)=N1
L(2)=N2

! First time only:
Status = DftiCreateDescriptor( Desc_Handle, DFTI_DOUBLE, DFTI_COMPLEX, 2, L )
Status = DftiCommitDescriptor( Desc_Handle )

! For each Trasform:
status = DftiComputeForward ( desc_handle, A )


Now I've updated the Fortran Compiler to the version 11.1.067, but the results of the same case now is wrong. I checked the user guide but I didn't find any specific change about the commands to be used.

Thanks for help,
Paolo

Hi Paolo,

The two results may be different because inputs are different, amongother possible reasons.
If you feel the computation is incorrect, please submit an issue at http://premier.intel.com

Thanks
