Hi all, So I am working with some nice symmetric and positive definite discretization, and have been told that algebraic multi-grid methods are best for solving these types of problems.
I see that there's GAMG and there's Hypre's BoomerAMG (and perhaps others too?) What exactly is the difference between these two? Do they have very different implementations under the hood? Does one have better scalability over another? Or more importantly, when would I choose one over the other? Thanks, Justin
