It was also shown later at the GPU Technology Conference in May 2012 (and that is the version shown on the PDF file).

The fast multipole method (FMM) is a numerical engine used in many applications, from acoustics, electrostatics, fluid simulations, wave scattering, and more.

Despite its importance, there is a lack of open community code, which arguably has affected its wider adoption. It is also a difficult algorithm to understand and to program, making availability of open-source implementations even more desirable.

ExaFMM is an open-source code base to utilize fast multipole algorithms, in parallel, and with GPU capability. The name reflects our viewpoint of the fast multipole method (FMM) as a rising star in the development of high-performance computing towards Exascale.
