Tutorial Objectives • Introduce the Portable, Extensible Toolkit for

Scientific Computation (PETSc) • Demonstrate how to write a complete parallel implicit PDE solver using PETSc • Learn about PETSc interfaces to other packages • How to learn more about PETSc 3 of 132 The Role of PETSc • Developing parallel, non-trivial PDE solvers that deliver high performance is still difficult, and requires months (or even years) of concentrated effort. • PETSc is a toolkit that can ease these difficulties and reduce the development time, but it is not a black-box PDE solver nor a silver bullet. 4 of 132 What is PETSc? • A freely available and supported research cod
