Semicoarsening Multigrid on a Hypercube
SIAM Journal on Scientific and Statistical Computing, 1992Summary: A semicoarsening multigrid algorithm suitable for the kinds of problems arising in reservoir simulation has been implemented on the Intel iPSC/2 hypercube. The method is an extension to nonsymmetric problems of a method by \textit{J. E. Dendy} jun., \textit{S. F. McCormick}, \textit{J. W. Runge}, \textit{T. F. Russek} and \textit{S. Schaffer} [

An introduction to algebraic multigrid [PDF]
Computing in Science and Engineering, 2006 Algebraic multigrid (AMG) solves linear systems based on multigrid principles, but in a way that only depends on the coefficients in the underlying matrix. The author begins with a basic introduction to AMG methods, and then describes some more recent advances and theoretical ...

Efficient numerical simulation of physical processes is constrained by our ability to solve the resulting linear systems, prompting substantial research into the development of multiscale iterative methods capable of solving these linear systems with an optimal amount of effort.

Constrainable Multigrid for Cloth
Computer Graphics Forum, 2013AbstractWe present a new technique which can handle both point and sliding constraints in the multigrid (MG) framework. Although the MG method can theoretically perform as fast as O(N), the development of a clothing simulator based on the MG method calls for solving an important technical challenge: handling the constraints.

Multigrid anisotropic diffusion
IEEE Transactions on Image Processing, 1998A multigrid anisotropic diffusion algorithm for image processing is presented. The multigrid implementation provides an efficient hierarchical relaxation method that facilitates the application of anisotropic diffusion to time-critical processes. Through a multigrid V-cycle, the anisotropic diffusion equations are successively transferred to coarser ...

Implementation of Multigrid on QPACE
2011 IEEE International Conference on Cluster Computing, 2011We developed and optimized a multigrid method on the QPACE cluster. The QPACE cluster is an acclerator-based cluster using the Power Cell 8i CPU that is built by the special research field SFB TR 55 for Lattice Quantum Chromo dynamics computations. The cluster uses a custom 3D to rus network build using FPGAs.
