Completely new smoother and/or solver classes derived from the
base objects in the library may be used without recompiling the
library itself. Once the new smoother/solver class has been
developed, the user can declare a variable of that new type in the
application, and pass that variable to the <code>p%set(solver,info)</code>
call; the new solver object is then dynamically included in the
preconditioner structure.
Developers can add completely new smoother and/or solver classes
derived from the base objects in the library may be used without
recompiling the library itself. To do so it is necessary first to
select the base type to be extended; in our experience, it is quite
likely that the new application needs only require the definition of a
``solver'' object, which is almost always acting only on the local
part of the distributed matrix. The parallel actions required to
connect the various solver objects are most often already provided by
the Block Jacobi or the Additive Schwarz smoothers.
To define a new solver, the developer will then have to define its
components and methods, perhaps taking one of the predefined solvers
as a starting point if possible.
<P>
<BR>
<P>
If the user has developed a new type of smoother and/or
solver by extending one of the base MLD2P4 types, and has declared a
variable of the new type in the main program, it is possible to pass
the new smoother/solver variable to the setup routine as follows:
Once the new smoother/solver class has been developed, to use it in
the context of the multilevel preconditioners it is necessary to:
<UL>
<LI>Declare in the application program a variable of the new type;
</LI>
<LI>Pass that variable as the argument to the se routine as in the
following:
<DIV ALIGN="CENTER">
<code>call p%set(smoother,info [,ilev, ilmax,pos])</code>
<BR><code>call p%set(solver,info [,ilev, ilmax,pos])</code>
</DIV>
In this way, the variable will act as a <I>mold</I> to which the
preconditioner will conform, even though the MLD2P4 library is not
modified, and thus has no direct knowledge about the new type.
</LI>
<LI>Link into the application executable the code implementing the
various methods.
</LI>
</UL>
The new solver object is then dynamically included in the
preconditioner structure, and will act as a <I>mold</I> to which the
preconditioner will conform, even though the MLD2P4 library has not
been modified to account for this new development.
<P>
It is possible to define new values for the keyword <code>WHAT</code> in the
<code>set</code> routines; if the library code does not recognize a keyword,
it passes it down the composition hierarchy (levels containing
smoothers containing solvers), so that it can be eventually caught by
the new solver.
