A comparison between Fast Multipole Algorithm and Tree – Code to evaluate gravitational forces in 3

We present tests of comparison between our versions of the Fast Multipole Algorithm (FMA) and " classic " tree–code to evaluate gravitational forces in particle systems. We have optimized the Greengard's original version of FMA allowing for a more efficient criterion of well–separation between boxes, to improve the adaptivity of the method (which is very… (More)
