Petsc 2.0: a Case Study of Using Mpi to Develop Numerical Software Libraries

  title={Petsc 2.0: a Case Study of Using Mpi to Develop Numerical Software Libraries},
  author={C. R. McInnes and Barry F. Smith},
The Portable, Extensible Toolkit for Scientiic computation (PETSc) is a toolbox for the parallel, numerical solution of elliptic and related partial diierential equations using nite element, nite diierence or related discretization techniques. In this paper we outline some of the major communication phases needed in many PETSc codes and discuss how MPI is used to handle them.
