Abstract: The parallel solution of nonlinear equations is at the heart of many simulations involving PDEs. Solving large-scale nonlinear equations presents challenges in algorithms, multi-level memory hierarchies, and the complexity of interactions among software tools for various phases of overall applications. This presentation will discuss an approach for solving such systems using the Portable, Extensible Toolkit for Scientific Computation (PETSc), with emphasis on algorithms and design strategies that enable us to achieve scalable performance. We will also discuss issues in component software interoperability, since one of the most difficult aspects of scientific simulations can be interfacing among a range of complementary tools for mesh management, discretization, linear algebra, optimization, visualization, etc.
