By default, npart=1 so all processes in the communicator participate in
the processing of the whole interval. If npart>1 then the interval is
divided into npart subintervals, each of them being processed by a
subset of processes.
<P>
The interval is split proportionally unless the separation points are
specified with <A HREF="../EPS/EPSKrylovSchurSetSubintervals.html#EPSKrylovSchurSetSubintervals">EPSKrylovSchurSetSubintervals</A>().
