<H3><FONT COLOR="#883300">Note</FONT></H3>
The default number of partitions is 1. This means the internal KSP object is shared
among all processes of the <A HREF="../EPS/EPS.html#EPS">EPS</A> communicator. Otherwise, the communicator is split
into npart communicators, so that npart KSP solves proceed simultaneously.
