FFT

Overview

The fast Fourier transform (FFT) is used in many domain applications—including molecular dynamics, spectrum estimation, fast convolution and correlation, signal modulation, and wireless multimedia applications, but current state-of-the-art FFT libraries are not scalable on large heterogeneous machines with many nodes.

The main objective of the FFT-ECP project is to design and implement a fast and robust 2-D and 3-D FFT library that targets large-scale heterogeneous systems with multi-core processors and hardware accelerators and to do so as a co-design activity with other ECP application developers. The work involves studying and analyzing current FFT software from vendors and open-source developers in order to understand, design, and develop a 3-D FFT-ECP library that could benefit from these existing optimized FFT kernels or will rely on new optimized kernels developed under this framework. Version 0.1 of the Highly Efficient FFTs for Exascale (heFFTe) library was released in October 2019, marking the first release for ICL’s FFT-ECP effort.
