Quasi two-dimensional Coulomb systems have drawn widespread interest. The reduced symmetry of these systems leads to complex collective behaviors, yet simultaneously poses significant challenges for particle-based simulations. In this paper, a novel

In this paper, fast and efficient discrete sine transformation (DST) algorithms are presented based on the factorization of sparse, scaled orthogonal, rotation, rotation-reflection, and butterfly matrices. These algorithms are completely recursive an

We present an MPI based software library for computing fast Fourier transforms (FFTs) on massively parallel, distributed memory architectures based on the Message Passing Interface standard (MPI). Similar to established transpose FFT algorithms, we p

In this paper we describe a parallel algorithm for calculating nonequispaced fast Fourier transforms on massively parallel distributed memory architectures. These algorithms are implemented in an open source software library called PNFFT. Furthermore

Starting from an approved serial algorithm, we develop a new parallel algorithm for calculating nonequispaced fast Fourier transforms on massively parallel distributed memory ar- chitectures. We demonstrate how to deal with the inherent load imbalanc
