This package provides Python bindings for the Message Passing
Interface (MPI) standard. It is implemented on top of the MPI-1/2/3
specification and exposes an API which grounds on the standard MPI-2
C++ bindings.
This package supports:
+ Communication of any picklable Python object
* Point-to-point: send & receive
* Collective: broadcast, scatter & gather, reductions
+ Communication of Python object exposing the Python buffer
interface (NumPy arrays, builtin bytes/string/array objects)
* Point-to-point: blocking/nonbloking/persistent send & receive
* Collective: broadcast, block/vector scatter & gather, reductions
+ Process groups and communication domains
* Creation of new intra/inter communicators
* Cartesian & graph topologies
+ Parallel input/output:
* read & write
* blocking/nonbloking & collective/noncollective
* individual/shared file pointers & explicit offset
+ Dynamic process management
* spawn & spawn multiple
* accept/connect
* name publishing & lookup
+ One-sided operations
* remote memory access: put, get, accumulate
* passive target syncronization: start/complete & post/wait
* active target syncronization: lock & unlock

2019-02-27 - Bernhard Wiedemann <>
- Use openmpi2 for releases that support it.
2019-02-25 - Tomá? Chvátal <>
- Update to 3.0.1:
* Bug fixes:
+ Fix ``Comm.scatter()`` and other collectives corrupting input send
list. Add safety measures to prevent related issues in global
reduction operations.
+ Fix error-checking code for counts in ``Op.Reduce_local()``.
* Enhancements:
+ Map size-specific Python/NumPy typecodes to MPI datatypes.
+ Allow partial specification of target list/tuple arguments in the
various ``Win`` RMA methods.
+ Workaround for removal of ``MPI_{LB|UB}`` in Open MPI 4.0.
+ Support for Microsoft MPI v10.0.
- Add numpy as build dependency used in tests
2018-11-15 - Todd R <>
- Use openmpi3 for releases that support it.

- Update to version 3.0.0
* New features:
+ `mpi4py.futures`: Execute computations asynchronously using a pool
of MPI processes. This package is based on ``concurrent.futures``
from the Python standard library.
+ ``: Run Python code and abort execution in case of
unhandled exceptions to prevent deadlocks.
+ `mpi4py.bench`: Run basic MPI benchmarks and tests.
* Enhancements:
+ Lowercase, pickle-based collective communication calls are now
thread-safe through the use of fine-grained locking.
+ The ``MPI`` module now exposes a ``memory`` type which is a
lightweight variant of the builtin ``memoryview`` type, but
exposes both the legacy Python 2 and the modern Python 3 buffer
interface under a Python 2 runtime.
+ The ``MPI.Comm.Alltoallw()`` method now uses ``count=1`` and
``displ=0`` as defaults, assuming that messages are specified
through user-defined datatypes.
+ The ``Request.Wait[all]()`` methods now return ``True`` to match
the interface of ``Request.Test[all]()``.
+ The ``Win`` class now implements the Python buffer interface.
* Backward-incompatible changes:
+ The ``buf`` argument of the ``MPI.Comm.recv()`` method is
deprecated, passing anything but ``None`` emits a warning.
+ The ``MPI.Win.memory`` property was removed, use the
``MPI.Win.tomemory()`` method instead.
+ Executing ``python -m mpi4py`` in the command line is now
equivalent to ``python -m``. For the former behavior,
use ``python -m mpi4py.bench``.
+ Python 2.6 and 3.2 are no longer supported. The ``mpi4py.MPI``
module may still build and partially work, but other pure-Python
modules under the ``mpi4py`` namespace will not.
+ Windows: Remove support for legacy MPICH2, Open MPI, and DeinoMPI.
- Switch to recommended openmpi2 for distributions that support it.
2017-10-25 -
- adapt to new openlmi package - source mpivars.h during build
2017-05-23 -
- Implement single-spec version
- Fix source URL.
- Package docs
2017-01-25 -
- Update description. Drop redundant %clean.
2017-01-24 -
- install LICENSE.rst as suggest in request#445611
2016-12-11 -
- Update to version 2.0.0
* Support for MPI-3 features.
* Support for MPI-2 features not included in previous releases.
* New scalable implementation of reduction operations for Python objects.
2013-10-24 -
- Update to version 1.3.1
* Regenerate C wrappers with Cython 0.19.1 to support Python 3.3.
* Install ``*.pxd`` files in ``<site-packages>/mpi4py`` to ease the
support for Cython's ``cimport`` statement in code requiring to
access mpi4py internals.
* As a side-effect of using Cython 0.19.1, ancient Python 2.3 is no
longer supported. If you really need it, you can install an older
Cython and run ``python build_src --force``.
