What is the effect of AMG solvers on the network bandwidth/latency given that AMG solvers generally require far fewer iterations to converge to a solution; therefore I am assuming that the number of messages and bandwidth is far less compared to other solvers? I guess I am looking at for the frequency at which AMG solvers transfer ghost data compared to others.
