the discussion <span style="mso-no-proof:yes">on</span>
implementing a variable-block size BILU
preconditioner, would it be possible to change the block size
parameter (bs) on
BAIJ format such that it can handle variable block sizes? (i.e.,
instead of it
being a scalar, it can be an array). Although BILU does not
necessarily require
rectangular blocks, <span style="mso-no-proof:yes">I</span>
think, it leads to <span style="mso-no-proof:yes">less</span>
messy code.</span></p>
