| Summary: MPI for Python | |
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

- Update to 3.0.3
* Regenerate Cython wrappers to support Python 3.8.
- Drop upstream-included fix_window_size.patch

- Add fix_window_size.patch
Fixes unit tests
See: https://bitbucket.org/mpi4py/mpi4py/issues/137/
* Wed Jul 31 2019 Todd R <toddrme2178@gmail.com>
- Update to 3.0.2
* Bug fixes:
+ Fix handling of readonly buffers in support for Pytho
2 legacy buffer interface. The issue triggers only when using
a buffer-like object that is readonly and does not export
the new Python 3 buffer interface.
+ Fix build issues with Open MPI 4.0.x series related to
removal of many MPI-1 symbols deprecated in MPI-2 and removed
in MPI-3.
+ Minor documentation fixes.
* Wed Feb 27 2019 Bernhard Wiedemann <bwiedemann@suse.com>
- Use openmpi2 for releases that support it.
* Mon Feb 25 2019 Tomáš Chvátal <tchvatal@suse.com>
- 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
* Thu Nov 15 2018 Todd R <toddrme2178@gmail.com>
- Use openmpi3 for releases that support it.
* Wed Jun 13 2018 toddrme2178@gmail.com
- 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.
+ `mpi4py.run`: 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 mpi4py.run``. 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.
