9 PETSc for parallel solving of linear and nonlinear equations

Abstract: The Portable, Extensible Toolkit for Scientific Computation (PETSc)39 is a set of data structures and routines used to implement large-scale scientific computations on parallel (and serial) computers. Only the basic features of PETSc and its solvers are discussed here.

9.1 Preliminaries

In this section, we consider the main possibilities of PETSc, its installation, and development of programs under this platform.

9.1.1 Brief description

PETSc provides a large set of tools for the numerical solution of partial differential equations on high-performance computers. It facilitates the development of large-scale applications in Fortran, ...
