There are two functions in this category: the value setting function

DftiSetValueDM

sets one particular configuration parameter to an appropriate value, the value getting function

DftiGetValueDM

reads the value of one particular configuration parameter.

Some configuration parameters used by cluster FFT functions originate from the conventional FFT interface (see Configuration Settings for details).

Other configuration parameters are specific to the cluster FFT. Integer values of these parameters have type

MKL_LONG

. The exact type of the configuration parameters being floating-point scalars is

float

or

double

. The configuration parameters whose values are named constants have the

enum

type

. They are defined in the

mkl_cdft.h

header file

.

Names of the configuration parameters specific to the cluster FFT interface have prefix

CDFT

.
