May tea-time: KokkosFFT: Performance-Portable Fast Fourier Transform interface for Kokkos Applications
May 20th 2026: Kokkos tea-time
CExA organizes the 19th Kokkos tea-time on Wednesday, May the 20th, 2026 for 45min starting at 7AM Pacific, 10AM Eastern, 4PM Paris, 11PM Tokyo. It can be followed on Zoom, or by phone.
Yuuichi Asahi will give a talk entitled “KokkosFFT: Performance-Portable Fast Fourier Transform interface for Kokkos Applications”
Yuuichi Asahi is a research scientist at Maison de la Simulation, CEA, France. He has focused on the nonlinear plasma turbulence by means of gyrokinetic simulations. High performance computing and large scale data management are key ingredients for these simulations. His current interests include accelerating the gyrokinetic simulation codes for more complicated physics, and analysing the large scale simulation results with machine/deep learning methods.
KokkosFFT: Performance-Portable Fast Fourier Transform interface for Kokkos Applications
Kokkos-FFT provides a unified, performance-portable interface for Fast Fourier Transforms (FFTs) within the Kokkos ecosystem. It seamlessly integrates with de facto standard FFT libraries, including FFTW, cuFFT, rocFFT, and oneMKL. Designed for simplicity and efficiency, Kokkos-FFT offers a user experience akin to numpy.fft for in-place and out-of-place transforms, while leveraging the raw speed of vendor-optimized libraries. Recently, we have implemented the prototype of the distributed version on top of MPI. In the talk, we will introduce the basic APIs and implementation details. We will present the benchmark results solving 3D Navier-Stokes equations with distributed FFTs. We will also present future development plans.
