Direct Schur Complement Method by Hierarchical Matrix Techniques …
WebIn this paper, we aim to accelerate the H-matrix vector multiplication by introducing mixed precision computing, where we employ both binary64 (FP64) and binary32 (FP32) arithmetic operations. We propose three methods to introduce mixed precision computing to H-matrix vector multiplication, and then evaluate them in a boundary element method (BEM) … WebHtool is an implementation of hierarchical matrices (cf. this reference or this one ), it was written to test Domain Decomposition Methods (DDM) applied to Boundary Element Method (BEM). It provides: routines to build hierarchical matrix structures (cluster trees, block trees, low-rank matrices and block matrices), the possibility to use Htool ... sonic hex

Web15 de nov. de 2004 · The adaptive cross approximation method can be used to efficiently approximate stiffness matrices arising from boundary element applications by hierarchical matrices. In this article an approximative LU decomposition in the same format is presented which can be used for preconditioning the resulting coefficient matrices efficiently. Web30 de out. de 2024 · Hierarchical Matrix (H-matrix) is an approximation technique which splits a target dense matrix into multiple submatrices, and where a selected portion of submatrices are low-rank approximated. The technique substantially reduces both time and space complexity of dense matrix vector multiplication, and hence has been applied to … http://www.hmatrix.org/ small houses for sale in los angeles
