<p class="topic-title">Abstract</p>
<p>This document describes <a class="reference external" href="http://gitlab.com/petsc/petsc4py">petsc4py</a>, a <a class="reference external" href="http://www.python.org">Python</a> port to the <a class="reference external" href="http://www.mcs.anl.gov/petsc/">PETSc</a>
libraries.</p>
<p><a class="reference external" href="http://www.mcs.anl.gov/petsc/">PETSc</a> (the Portable, Extensible Toolkit for Scientific
Computation) is a suite of data structures and routines for the
scalable (parallel) solution of scientific applications modeled by
partial differential equations. It employs the <a class="reference external" href="http://www.mpi-forum.org">MPI</a> standard for
all message-passing communication.</p>
<p>This package provides an important subset of PETSc functionalities
and uses <a class="reference external" href="http://www.numpy.org">NumPy</a> to efficiently manage input and output of array data.</p>
<p>A <em>good friend</em> of petsc4py is:</p>
