Recent Advances in PETSc Scalable Solvers

Dr. Lois Curfman McInnes, Argonne National Laboratory, U.S.A.

2 Jul 2012, 14:00; Location: S4|10-1

We will discuss recent advances in the Portable, Extensible Toolkit for Scientific computing (PETSc) that enable application scientists to develop composable linear, nonlinear, and timestepping solvers for multiphysics and multilevel methods on emerging extreme-scale architectures.  Examples of usage include lithosphere dynamics, subduction and mantle convection, ice sheet dynamics, subsurface reactive flow, fusion, mesoscale materials modeling, and power networks.  We will also discuss how solver composability enables the development of hierarchical Krylov methods, which overcome well-known limitations in scaling of conventional Krylov methods due to global reductions.
