<p class="topic-title first">Abstract</p>
<p>This document describes the <em>MPI for Python</em> package. <em>MPI for
Python</em> provides bindings of the <em>Message Passing Interface</em> (MPI)
standard for the Python programming language, allowing any Python
program to exploit multiple processors.</p>
<p>This package is constructed on top of the MPI-1/2 specifications
and provides an object oriented interface which closely follows
MPI-2 C++ bindings. It supports point-to-point (sends, receives)
and collective (broadcasts, scatters, gathers) communications of
any <em>picklable</em> Python object, as well as optimized communications
of Python object exposing the single-segment buffer interface
(NumPy arrays, builtin bytes/string/array objects)</p>
