PETSc: Portable, Extensible Toolkit for Scientific Computation
==============================================================

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. It employs the Message Passing Interface (MPI) standard for
all message-passing communication.
