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.
