As I recall we attached the eigenstates to the matrix. Is that old attach
mechanism still the used/recommended? Or is there a better way to do this
now?
Thanks,

Before we stored them in the matrix. When you get to the test in Cheby you
don't have caller anymore (GAMG).

Oh, the eigenvalues are the preconditioned ones, the PC (Jacobi) matters

It's been a few years since we lost the ability to cache the eigen
estimates, that smoothed aggregation computes, to chebyshev smoothers. I'd
like to see if we bring this back.
This is slightly (IMO) complicated by the fact that the smoother PC may not
be Jacobi, but I think it is close enough (an
