Cluster FFT Descriptor Configuration Functions

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
.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
