Hello !
I wrote an application in order to time the maximum 1d 1024points FFT calculation i can.
When i set the application to run more than 12686 FFT, terminal answers :
cufft: ERROR: /root/cuda-stuff/sw/gpgpu_rel1.1/cufft/src/execute.cu, line 1038
cufft: ERROR: CUFFT_EXEC_FAILED
cufft: ERROR: /root/cuda-stuff/sw/gpgpu_rel1.1/cufft/src/cufft.cu, line 119
cufft: ERROR: CUFFT_EXEC_FAILED
It seems that those files exist only during the run…
Anyone know about a maximum of FFT, or points, that can be computed in one plan ?
(I red about a maximum of 8M points per plan, but with 12686 1k fft, 12 990 464 points are set in the plan)
