WebFor double precision benchmark, replace -vkfft 0 -cufft 0 with -vkfft 1 -cufft 1. For half precision benchmark, replace -vkfft 0 -cufft 0 with -vkfft 2 -cufft 2. How to use VkFFT. … WebJan 22, 2024 · CuFFT supports complex half. Enable matrix multiplication operations. This unfortunately is not supported by cublas. Alternatives are using Triton, or doing 3 or 4 real matrix multiplications with corresponding copies to accommodate complex data layout.
WebThe popular NVIDIA cuFFT library provides a simple interface to compute 2D FFT on GPUs, but it’s yet to utilize the recent hardware advancement in half-precision floating-point arithmetic. WebOct 23, 2024 · CuPy CuFFT ~2x faster than CUDA.jl CuFFT. I am working on a simulation whose bottleneck is lots of FFT-based convolutions performed on the GPU. I wanted to see how FFT’s from CUDA.jl would compare with one of bigger Python GPU libraries CuPy. I was surprised to see that CUDA.jl FFT’s were slower than CuPy for moderately sized …
WebFeb 20, 2024 · After playing around with the worksize estimating functions, it seems that CUFFT is requiring an amount of extra work space equal to the size of the input/output arrays for the transform. Should this really be the case? There is no way no minimize this footprint if I want to execute several identical plans with different batch lengths? WebOct 19, 2016 · Storing FP16 (half precision) data compared to higher precision FP32 or FP64 reduces memory usage of the neural network, allowing training and deployment of larger networks, and FP16 data …
