Title: Distributed Memory Fast Fourier Transforms in the Exascale Era

Authors: Samar Aseeri (King Abdullah University of Science and Technology)

Abstract: In this project, we plan to improve the implementation of the Fast Fourier Transform (FFT) on emerging high-performance computing architectures and galvanize the international community of experts to benchmark our and their efforts, leading the faster and more efficient adoption of the best FFT software Technology.

FFT is an accurate low computational cost algorithm that is widely used for high-performance computing and engineering applications and it will still be needed on exascale computers. The implementations of the FFT (and other fast transforms) require many long-range interprocessor communications, which are a parallelization bottleneck. Therefore, the identification of alternative algorithms to the FFT along with comparisons of efficiency will lead to optimal use of high-performance computers. In this lightning talk, I will highlight the project objective, approach, and expected outcome.
