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. CCS CONCEPTS WebThe cuFFT API is modeled after FFTW, which is one of the most popular and efficient CPU-based FFT libraries. cuFFT provides a simple configuration mechanism called a plan that uses internal building blocks to optimize the transform for the given …
