[petsc-users] Dense matrix solver

[Frank]

Hi,

I am thinking of solving a linear equations, whose coefficient matrix
has 27 nonzero diagonal bands(diagonal dominant). Does any body have any
idea about how this will perform? Do you have any recommendation about
which solver to choose?
I have solved a 11 nonzero diagonal bands matrix equation with
"boomeramg", which is 50% solwer than 7 nonzero diagonal bands.

Thanks.
