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 (oneMKL) 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 (oneMKL) to avoid using the auxiliary storage if possible.
