In basin and reservoir simulations, the most expensive and time consuming phase is solving
systems of linear equations using Krylov subspace methods such as BiCGStab. For this
reason, we explore the possibility of using communication avoiding Krylov subspace
methods (s-step BiCGStab), that speedup of the convergence time on modern-day
architectures, by restructuring the algorithms to reduce communication. We introduce some
variants of s-step BiCGStab with better numerical stability for the targeted systems.
