MKL sequential parallel option and FFT

[Jack_K_]

Hi, I got an question.

What is different between sequential and parallel options in mkl ?

When I try to use FFT, two different options bring me two different answers. ( The input and output are different size in FFT)

Thanks.

Jack,  What the computation difference have you seen with the sequential and treaded modes of MKL?  Thanks.
