A Comparison of Distributed Memory Fast Fourier Transform (FFT) Library Packages

In this BoF developers and users of different FFT packages will answer the following questions in short presentations that lasts not more than 10 min.

Following these questions, there will be a general discussion between the presenters along with audience interaction. Contributions will highlight existing or potential bottlenecks in the different FFT packages; possible methods to overcome them as well as FFT interface design.
