I’m trying to use cufft for image processing.
But, I found strange behaviour of cufft.
When I try to transform 640x640 images, cufft works well.
But, for other sized images, e.g 639x639 images, it fails.
I’m wondering why this happens.
for some sizes, it works well, but for other sizes, it fails with different error messages. Sometimes, it fails with CUFFT_EXEC_FAILED, and sometimes, with CUFFT_INTERNAL_ERROR.
I’m using WinXP 32bit, MS VC++ 2005, GTX680 and CUDA 2.0.
Hello sodomau, I have I question…2D Complex-to-Complex Transform, how can I do source data creation?.. i mean, i’m trying to probe 2D C2C trasfom, but I don’t know how to load data to trasform!.. please tell me…
