-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2017-e36735026b 2018-01-23 19:59:59.973775 --------------------------------------------------------------------------------

Name : mld2p4 Product : Fedora EPEL 7 Version : 2.1.0 Release : 6.el7 URL : https://github.com/sfilippone/mld2p4-2 Summary : MultiLevel Domain Decomposition Parallel Preconditioners Package based on PSBLAS Description : The MULTI-LEVEL DOMAIN DECOMPOSITION PARALLEL PRECONDITIONERS PACKAGE BASED ON PSBLAS (MLD2P4) provides multi-level Schwarz preconditioners, to be used in the iterative solutions of sparse linear systems:

Ax=b

where $A$ is a square, real or complex, sparse matrix with a symmetric sparsity pattern. These preconditioners have the following general features:

- both additive and hybrid multilevel variants are implemented, i.e. variants that are additive among the levels and inside each level, and variants that are multiplicative among the levels and additive inside each level; the basic Additive Schwarz (AS) preconditioners are obtained by considering only one level;

- a purely algebraic approach is used to generate a sequence of coarse-level corrections to a basic AS preconditioner, without explicitly using any information on the geometry of the original problem (e.g. the discretization of a PDE). The smoothed aggregation technique is applied as algebraic coarsening strategy.
