[petsc-users] ML spectral radius estimate

I'm using ML as a preconditioner, and I want to get an estimate of the
spectral radius of my preconditioned matrix. I see a flag
-pc_ml_SpectralNormScheme_Anorm. Does this need to be set in conjunction
with another flag like -ksp_compute_eigenvalues or something cool I don't
know about?
