HiPC 2018 WORKSHOP 1: Parallel Fast Fourier Transforms (PFFT)

Abstract

The goal of this workshop is to encourage discussions about FFTs and to discover a benchmark suite that is widely accepted for computer co-design. This workshop is part of an initiative project that plans a series of meetings at different international venues with the aim of forming a community in order to collect the viewpoints of users, developers and vendors. FFT is an accurate lowcost algorithm which is extensively used in many parallel applications such as signal processing, astronomy and fluid dynamics. However, it might not run well on a full parallel computer due to its Alltoall communication limitations. Consequently, it is of interest to the High Performance Computing community to address related challenges and seek solutions.
