4PETSc: Portable, Extensible Toolkit for Scientific Computation
5==============================================================
6
7The Portable, Extensible Toolkit for Scientific Computation (PETSc),
8is a suite of data structures and routines for the scalable (parallel)
9solution of scientific applications modeled by partial differential
10equations. It employs the Message Passing Interface (MPI) standard for
11all message-passing communication.
