We do not have a band matrix type. I believe there are good parallel
tridiagonal solvers out there, but currently we do not support them.
However, you can use AIJ without much overhead.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which
their experiments lead.
