<LI>On entry to this routine the descriptor must be in the
|
|
assembled state, i.e. <code>psb_cdasb</code> must already have been called.
|
|
</LI>
|
|
<LI>The sparse matrix may be in either the build or update state;
|
|
</LI>
|
|
<LI>Duplicate entries are detected and handled in both build and
|
|
update state, with the exception of the error action that is only
|
|
taken in the build state, i.e. on the first assembly;
|
|
</LI>
|
|
<LI>If the update choice is <code>psb_upd_perm_</code>, then subsequent
|
|
calls to <code>psb_spins</code> to update the matrix must be arranged in
|
|
such a way as to produce exactly the same sequence of coefficient
|
|
values as encountered at the first assembly;
|
|
</LI>
|
|
<LI>The output storage format need not be the same on all
|
|
processes;
|
|
</LI>
|
|
<LI>On exit from this routine the matrix is in the assembled state,
|
|
and thus is suitable for the computational routines.
