Overview

This package provides Python bindings for the Message Passing Interface (MPI <https://www.mpi-forum.org/>_) standard. It is implemented on top of the MPI specification and exposes an API which grounds on the standard MPI-2 C++ bindings.

Dependencies

• Python <https://www.python.org/>_ 3.6 or above, or PyPy <https://www.pypy.org/>_ 7.2 or above.

• An MPI implementation like MPICH <https://www.mpich.org/>_ or Open MPI <https://www.open-mpi.org/>_ built with shared/dynamic libraries.

• To work with the in-development version, you need to install Cython <https://cython.org/>_.
