Webexecute () will assume that context, corresponding to given one is active at the time of the call. New Stream is created each time execute () is called and destroyed if wait_for_finish finally evaluates to True. Default value of wait_for_finish is True. OpenCL ¶ Either context or queue must be set. queue is not None: queue is remembered and used. WebJun 1, 2014 · Power of 2 is not necessary for all FFT implementations, and it seems that CUFFT can cope with non power of 2 for larger FFT sizes anyway, where it uses multiples of 512 instead. For convolution you can't usually make the FFT size a power of 2, because the dimensions needs to be image_dimension + kernel_dimension - 1, hence the need for …
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.
