Introduction to PETSc

, 2021
The Portable, Extensible Toolkit for Scientific Computation (PETSc) is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations (www.mcs.anl.gov/petsc/). It enables researchers to delegate the linear algebra part of their applications to a specialized team, and to ...

Extreme-Scale Multigrid Components within PETSc [PDF]

Proceedings of the Platform for Advanced Scientific Computing Conference, 2016
Elliptic partial differential equations (PDEs) frequently arise in continuum descriptions of physical processes relevant to science and engineering. Multilevel preconditioners represent a family of scalable techniques for solving discrete PDEs of this type and thus are the method of choice for high-resolution simulations.
