FFT, FMM, or Multigrid? A comparative Study of State-Of-the-Art Poisson Solvers for Uniform and Nonuniform Grids in the Unit Cube

Amir Gholami, Dhairya Malhotra, Hari Sundar +1

In this work, we benchmark and discuss the performance of the scalable methods for the Poisson problem which are used widely in practice: the fast Fourier transform (FFT), the fast…

Comparison of Multigrid Algorithms for High-order Continuous Finite Element Discretizations

Hari Sundar, Georg Stadler, George Biros

We present a comparison of different multigrid approaches for the solution of systems arising from high-order continuous finite element discretizations of elliptic partial differen…
