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.
