very concrete question:
Does FFTW3 wrapper library, which is described here:
support wisdom mechanism? In particular, any of these functions:
In principle, in the documentation in the link I've pasted above it's written that the wrapper library does not support these functions ("All wrappers are empty and do nothing"). However, in my program, I get always 1 as a result of these functions, which should mean that the import of wisdom has succeeded (documentation out of date?). On the other hand, timings of the programs' execution may suggest that the import of wisdom has "failed".
I would be really grateful for a clear explanation of the issue.
The fftw import wisdomfunctions are all empty, as you can see in mk/interfaces/fftw3xc. Each of the functionswould always return 0, meaning the import operation was NOT SUCCESSFUL.This interpretation may disagree with expectation of particularapplication, but it should trigger exception processing branch of the user application, whichisarguably preferred interpretation.
Thank you Dima for your quick reply.
Still, I feel that such "advanced" compilers as these provided by Intel should definitely support wisdom mechanism. It's one of the biggest advantages of FFTW.
