The performance of the adaptive smooth aggregation multigrid
(SA) algorithm suffers for non-symmetric problems. I
will present a non-symmetric version of the algorithm that
uses Kaczmarz iteration as a relaxation step and smoothed
aggregation of local right and left singular vectors to form
a hierarchy of coarse grid operators. Testing has been done
on one and two dimensional convection dominated
convection-diffusion. I will present the current results and
struggles of these tests. Expect some whining.
