DFTI_COMMIT_STATUS

The
DFTI_COMMIT_STATUS
 configuration parameter indicates whether the descriptor is ready for computation. The parameter has two possible values:
DFTI_UNCOMMITTED
Default value, set after a successful call of
DftiCreateDescriptor
.
DFTI_COMMITTED
The value after a successful call to
DftiCommitDescriptor
.
A computation function called with an uncommitted descriptor returns an error.
You cannot directly set this configuration parameter in a call to
DftiSetValue
, but a change in the configuration of a committed descriptor may change the commit status of the descriptor to
DFTI_UNCOMMITTED
.

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.
