VkFFT – Vulkan Fast Fourier Transform Library

If I were a hiring person at AMD or Intel, I'd shortlist this guy for a job, as they need help competing against the headstart CUDA has in the GPU-base compute space.

Hello, I am the author of VkFFT, Tolmachev Dmitrii. I remember VkFFT got a lot of initial traction thanks to Hacker News three years ago. Back then VkFFT was a simple collection of pre-made shaders for powers of two FFTs. Nowadays it is based on the runtime code generation and optimization platform that supports all the mentioned backends, has a wide range of implemented algorithms (some of which are not even present in other codes) to cover all system sizes…

Hello! Since the last post VkFFT has experienced a number of huge improvements and optimizations. Namely: -It now supports sequences up to 2^32 in all dimensions (algorithmically, in reality limited to allocatable memory size, switch to 64-bit addressing scheme is planned for future release) -configurations optimized for bigger range of systems and vendors -benchmarked Radeon VII and RTX 3080, shows that FFT is extremely bandwidth limited on modern GPUs -VkFFT is able to match and outperform cuFFT on the whole…
