[petsc-users] Why use MATMPIBAIJ?

Hi Matt
I would rather like to set the block size for block P2 too. Why?
Because in one of my test (for problem involves only [u_x u_y u_z]), the
gmres + Hypre AMG converges in 50 steps with block size 3, whereby it
increases to 140 if block size is 1 (see attached files).
This gives me the impression that AMG will give better inversion for "P2"
block if I can set its block size to 3. Of course it's still an hypothesis
but worth to try.
Another question: In one of the Petsc presentation, you said the Hypre AMG
does not scale well, because set up cost amortize the iterations. How is it
quantified? and what is the memory overhead?
