The white paper of VkFFT is out. It can be interesting to people who want to know more about performant GPU algorithms in HPC and how VkFFT is designed.

VkFFT is an efficient GPU-accelerated multidimensional Fast Fourier Transform library for Vulkan/CUDA/HIP/OpenCL/Level Zero and Metal projects. VkFFT aims to provide the community with a cross-platform open-source alternative to vendor-specific solutions while achieving comparable or better performance.
