SUMMARY:VkFFT – Vulkan/CUDA/HIP/OpenCL/Level Zero GPU FFT Library
DESCRIPTION:Posters, Research Posters\n\nVkFFT – Vulkan/CUDA/HIP/OpenCL/Le
 vel Zero GPU FFT Library\n\nTolmachev\n\nThe Fast Fourier Transform is an 
 essential algorithm of modern computational science. The highly parallel s
 tructure of the FFT allows for its efficient implementation on graphics pr
 ocessing units (GPUs), which are now widely used for general-purpose compu
 ting. This poster presents the VkFFT - an efficient GPU-accelerated multid
 imensional Fast Fourier Transform library for Vulkan/CUDA/HIP/OpenCL/Level
  Zero projects. VkFFT aims to provide the community with a cross-platform 
 open-source alternative to vendor-specific solutions while achieving compa
 rable or better performance. This poster presents the optimizations implem
 ented in VkFFT and compares its performance and precision against Nvidia c
 uFFT and AMD's rocFFT libraries on their latest HPC GPUs. This poster also
  presents the first performant implementation of Discrete Cosine Transform
 s on GPUs. VkFFT is released under MIT license.\n\nRegistration Category:
