AMG4PSBLAS is a package of Algebraic MultiGrid (AMG)
|
|
preconditioners for the iterative solution of large and sparse linear systems.
|
|
|
|
It is an evolution of MLD2P4 (see LICENSE.MLD2P4), but it has been
|
|
thoroughly reworked, and it is sufficiently different to warrant a new
|
|
project name.

TO COMPILE
|
|
|
|
0. Unpack the tar file in a directory of your choice (preferrably
|
|
outside the main PSBLAS directory).
|
|
1. run configure --with-psblas=<ABSOLUTE path of the PSBLAS install directory>
|
|
adding the options for MUMPS, SuperLU, SuperLU_Dist, UMFPACK as desired.
|
|
See MLD2P4 User's and Reference Guide (Section 3) for details.
|
|
2. Tweak Make.inc if you are not satisfied.
|
|
3. make;
|
|
4. Go into the test subdirectory and build the examples of your choice.
|
|
5. (if desired): make install
|

|
NOTES
|
|
|
|
- The single precision version is supported only by MUMPS and SuperLU;
|
|
thus, even if you specify at configure time to use UMFPACK or SuperLU_Dist,
|
|
the corresponding preconditioner options will be available only from
|
|
the double precision version.
