Distributed Memory Fast Fourier Transform (FFT) Library
The aim of this BoF is to discuss the current state of the art on FFT applications and implementations as well as benchmark suite for FFTs. To allow for comparisons of different Fourier transform libraries, in a previous venue, the FFT developers discussed the possibility of having a common test case study and what would be a good way to benchmark FFT. At other venues, speakers highlighted existing or potential bottlenecks in the different FFT packages and proposed how to overcome them. Presentations will be made available at http://www.fft.report which already contains presentations of previous viewpoints on the FFT. Thereon, this BoF is a third meeting of its kind after two previous ones. The first, SC'17 BoF, have addressed an FFT package comparison where developers of a number of these packages gave feedback on the FFT software they had published. The second venue BoF at ISC'18 have discussed what can be achieved for FFT in the Exsascale era.
