Multiscale Numerics for the Atmosphere and Ocean

In this talk, I will outline the role of iterative solvers in building scalable methods and describe the bottleneck in such solvers. In particular, I will review GMRES and BiCGStab. After, this we will review preconditioning and describe the preconditioners that we have tried and those that we have been developing. The preconditioners that we describe fall under the general category of Sparse Approximate Inverse (SPAI) Preconditioner.
