DFTI_WORKSPACE
The computation step for some FFT algorithms requires a scratch space for permutation or other purposes. To manage the use of the auxiliary storage, Intel® oneAPI Math Kernel Library enables you to set the configuration parameterDFTI_WORKSPACE with the following values:
DFTI_ALLOW |
(default) Permits the use of the auxiliary storage. |
DFTI_AVOID |
Instructs Intel® oneAPI Math Kernel Library to avoid using the auxiliary storage if possible. |
