WebJul 15, 2024 · The ‘bad’ dataset has box size 256, pixel size 0.836 (0.413 downsample 2x) , and global resolution ~6.5. The other, ‘succesful’ datasets have the same pixel size, global resolutions in the 4.5-7.5 A, and box sizes of 256 - 420. For some mysterious reasons, the traceback on the bad dataset is now complaining about about cuda memory ... WebNov 30, 2010 · The function cufftExecZ2Z does not give the same answer as the equivalent FFTW3 function. For the exactly same input array, the first few output elements are shifted by 2 positions and after around 50 elements, the signs seems to be reverse at least for the real part. This is for a Plan3d (30,30,30) transform. Webpattern. We evaluated our tcFFT and the NVIDIA cuFFT in vari-ous sizes and dimensions on NVIDIA V100 and A100 GPUs. The results show that our tcFFT can outperform cuFFT 1.29x-3.24x and 1.10x-3.03x on the two GPUs, respectively. Our tcFFT has a great potential for mixed-precision scientific applications.
