This directory contains the MLD2P4 set of preconditioners, version 2.0 This directory contains the MLD2P4 set of preconditioners, version 2.1
WHAT'S NEW WHAT'S NEW
Version 2.1
1. The multigrid preconditioner now include fully general V- and W-
cycles. We also support K-cycles, intended to be used in
conjunction with Flexible CG available in PSBLAS 3.5.
2. The smoothers now include popular
variants such as Jacobi, forward and backward hybrid
Gauss-Seidel (intra-process Gauss-Seidel, inter-process
block-Jacobi).
3. The PRE and POST specification for smoothers can now be
specified independently of each other: you can even specify
different smoothers for PRE and POST (e.g. forward Gauss-Seidel
PRE with backward Gauss-Seidel POST). The default is to
have the specs apply to both PRE and POST.
Version 2.0. Version 2.0.
Finally moved to F2003, with the support of PSBLAS3. Finally moved to F2003, with the support of PSBLAS3.
