AbstractWe describe our implementation of a parallel fast multipole method for evaluating potentials for discrete and continuous source distributions. The first requires summation over the source points and the second requiring integration over a continuous source density. Both problems require(N2) complexity when computed directly; however, can be accelerated to(N) time using FMM. In our PVFMM software library, we use kernel independent FMM and this allows us to compute potentials for a widedoi:10.4208/cicp.020215.150515sw fatcat:bagey7wevzgtzg4ocx5syyotce
