This talk focuses on recent developments in hypre, a high-performance library for solving large, sparse linear systems, widely used in computational science and engineering. We highlight advances in ...

Dear hypre developers and users, Greetings! I am a user of hypre who regularly employs various algebraic multigrid methods provided by hypre to solve my linear systems, such as BoomerAMG, SMG, and ...

In the compression of scientific data, error-controlled compressors enable to considerably decrease the size of the dataset while maintaining adequate levels of accuracy. In this paper, we note that ...

The electrostatic solver has two methods to choose from, "Multigrid" and "FFT." I want to use FFT. I follow the documentation, which says that FFT only works: in 3D with "open" boundary conditions for ...

Abstract: In this paper, we propose a tensor multigrid method and an iterative tensor multigrid method to solve the Sylvester tensor equations which may arise from the discretization of high order ...

A large system of equations comes out from discretization of the domain of partial differential equations into a collection of points and the optimal method for solving these problems is multigrid ...

In [1], the author introduced a wavelet multigrid method that used the wavelet transform to define the coarse grid, interpolation, and restriction operators for the multigrid method. In this paper, we ...
