I get the error:
CUFFT_SETUP_FAILED CUFFT library failed to initialize.
The portion of my code (snippet) to call cufft is as follows:
Â result = cufftExecC2C(plan, rhs_complex_d, rhs_complex_d, CUFFT_FORWARD); mexPrintf("Execution Code: %d.\n",result);
This is in a mex wrapper for matlab and I have it echo out the error code. I compile my code fine and it runs but the array is just passed to the card and returned unprocessed. The Planner (cufftPlan1d) is working just fine.
I have literally spent 8 hours trying to figure this out. I dunno what is up with this :(. I am running Windows Vista, the newest driver (released today), have an 8800 GTS. Again it compiles and runs without error but the cufft library wont initialize and it returns the array. I have the CUDA toolkit and SDK installed (version 2 Beta).
Thank you for any help :)!
EDIT: I corrected that I do have 2 beta installed.
