We describe the basics for building and applying AMG4PSBLAS one-level and multilevel
(i.e., AMG) preconditioners with the Krylov solvers included in PSBLAS \cite{PSBLASGUIDE}.
This section describes the basics for building and applying
AMG4PSBLAS one-level and multilevel (i.e., AMG) preconditioners with
the Krylov solvers included in PSBLAS \cite{PSBLASGUIDE}.
The following steps are required:
\begin{enumerate}
\item \emph{Declare the preconditioner data structure}. It is a derived data type,
\verb|amg_|\-\emph{x}\verb|prec_| \verb|type|, where \emph{x} may be \verb|s|, \verb|d|, \verb|c|
or \verb|z|, according to the basic data type of the sparse matrix
(\verb|s| = real single precision; \verb|d| = real double precision;
\verb|c| = complex single precision; \verb|z| = complex double precision).
This data structure is accessed by the user only through the AMG4PSBLAS routines,
following an object-oriented approach.
\item \emph{Allocate and initialize the preconditioner data structure, according to
a preconditioner type chosen by the user}. This is performed by the routine
\fortinline|init|, which also sets defaults for each preconditioner
type selected by the user. The preconditioner types and the defaults associated
with them are given in Table~\ref{tab:precinit}, where the strings used by
\fortinline|init| to identify the preconditioner types are also given.
Note that these strings are valid also if uppercase letters are substituted by
corresponding lowercase ones.

letters are substituted by corresponding lowercase ones.
\item \emph{Modify the selected preconditioner type, by properly setting
preconditioner parameters.} This is performed by the routine \fortinline|set|.
This routine must be called only if the user wants to modify the default values
of the parameters associated with the selected preconditioner type, to obtain a variant
of that preconditioner. Examples of use of \fortinline|set| are given in
Section~\ref{sec:examples}; a complete list of all the
preconditioner parameters and their allowed and default values is provided in
Section~\ref{sec:userinterface}, Tables~\ref{tab:p_cycle}-\ref{tab:p_smoother_1}.
