Subject: [mpi4py] [ANN] mpi4py release 3.0.0
To: mpi4py <mpi4py(a)googlegroups.com>
* 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.
