PETSc will provide a new solver interface to structured adaptive mesh refinement (SAMR), enabling the efficient representation of multi-scale phenomenon, while maintaining the simplicity of structured grid kernel computations. We will use the most asymptotically efficient solvers for strongly nonlinear equations: matrix-free full approximation scheme (FAS) nonlinear full multi-grid (FMG) methods. These formulations have a unique opportunity to leverage modern architectures to deliver fast, accurate, versatile solvers for complex, multi-physics application. In particular, we are working closely with the premier open source, state-of-the-art massively parallel subsurface flow and reactive transport code -- PFLOTRAN. This work is significant in that it radically changes algorithms, data access, and low level computational organization in order to maximize performance and scalability on modern Intel architectures, and encapsulates this knowledge in the PETSc libraries for the broadest possible impact.
