-------------------------------------------------------------------
Sun Dec 22 17:21:34 UTC 2024 - Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Fix packaging of header files, breaking VTK openmpi builds.
E.g. mpi4py.h requires the MPI_api.h in a specific relative
location.
-------------------------------------------------------------------
Fri Nov 22 20:47:58 UTC 2024 - Ben Greiner <code@bnavigator.de>
- Update to 4.0.1
## Update support for Python 3.13:
* Enable Cython 3.1 support for free-threaded CPython.
* Allow compiling Cython-generated C sources with the full Python
C-API.
* Fix MPI DLL path workarounds on Windows after changes to
locals().
## Enhancements to test suite:
* Support XML reports via unittest-xml-reporting.
* Add command line options to exclude tests by patterns and
files.
* Refactor Python 2 code to use Python 3 constructs using
pyupgrade.
## Miscellaneous:
* Minor and mostly inconsequential subclass fix in
mpi4py.util.pkl5.
* Update compatibility workarounds for legacy MPICH 3.0 release.
- Release 4.0.0
## New features:
### Add support for the MPI-4.0 standard.
* Use large count MPI-4 routines.
* Add persistent collective communication.
* Add partitioned point-to-point communication.
* Add new communicator constructors.
* Add the Session class and its methods.
### Add support for the MPI-4.1 standard.
* Add non-destructive completion test for multiple requests.
* Add value-index datatype constructor.
* Add communicator/session buffer attach/detach/flush.
* Support for removal of error classes/codes/strings.
* Support for querying hardware resource information.
### Add preliminary support for the upcoming MPI-5.0 standard.
* User-level failure mitigation (ULFM).
* mpi4py.util.pool: New drop-in replacement for
multiprocessing.pool.
* mpi4py.util.sync: New synchronization utilities.
* Add runtime check for mismatch between mpiexec and MPI library.
* Support scikit-build-core as an alternative build backend.
* Support meson-python as an alternative build backend.
## Enhancements:
* mpi4py.futures: Support for parallel tasks.
* mpi4py.futures: Report exception tracebacks in workers.
* mpi4py.util.pkl5: Add support for collective communication.
* Add methods Datatype.fromcode(), Datatype.tocode() and
attributes Datatype.typestr, Datatype.typechar to simplify
NumPy interoperability for simple cases.
* Add methods Comm.Create_errhandler(), Win.Create_errhandler(),
and File.Create_errhandler() to create custom error handlers.
* Add support for pickle serialization of instances of MPI types.
All instances of Datatype, Info, and Status can be serialized.
Instances of Op can be serialized only if created through
mpi4py by calling Op.Create(). Instances of other MPI types can
be serialized only if they reference predefined handles.
* Add handle attribute and fromhandle() class method to MPI
classes to ease interoperability with external code. The handle
value is an unsigned integer guaranteed to fit on the
platform's uintptr_t C type.
* Add lowercase free() method to MPI classes to ease MPI object
deallocation and cleanup. This method eventually attempts to
call Free(), but only if the object's MPI handle is not a null
or predefined handle, and such call is allowed within the World
Model init/finalize.
## Backward-incompatible changes:
* Python 2 is no longer supported, Python 3.6+ is required, but
typing stubs are supported for Python 3.8+.
* The Intracomm.Create_group() method is no longer defined in the
base Comm class.
* Group.Compare() and Comm.Compare() are no longer class methods
but instance methods. Existing codes using the former class
methods are expected to continue working.
* Group.Translate_ranks() is no longer a class method but an
instance method. Existing codes using the former class method
are expected to continue working.
* The LB and UB datatypes are no longer available, use
Datatype.Create_resized() instead.
* The HOST predefined attribute key is no longer available.
* The MPI.memory class has been renamed to MPI.buffer. The old
name is still available as an alias to the new name.
* The mpi4py.dl module is no longer available.
* The mpi4py.get_config function returns an empty dictionary.
## Miscellaneous:
* The project is now licensed under the BSD-3-Clause license.
This change is fairly inconsequential for users and
distributors. It simply adds an additional clause against using
contributor names for promotional purposes without their
consent.
* Add a new guidelines section to documentation laying out new
fair play rules. These rules ask companies and outside
developers to refrain from reusing the mpi4py name in
unaffiliated projects, publishing binary mpi4py wheels on the
main Python Package Index (PyPI), and distributing modified
versions with incompatible or extended API changes. The primary
motivation of these rules is to avoid fragmentation and
end-user confusion.
- Skip failing tests: test fails are different on server and local
machines. TODO: Investigate
- Remove unused rpm macro file: Static %mpi4py_mpi_ver is not used
anywhere (and had a strange name for value 'openmpi')

futures at shutdown. Environment variables names now follow
the pattern MPI4PY_FUTURES_*, the previous MPI4PY_* names are
deprecated.

docstring of functions and methods displays a signature
including type annotations.

removal of many MPI-1 symbols deprecated in MPI-2 and removed
in MPI-3.

-------------------------------------------------------------------
Thu Nov 15 04:50:38 UTC 2018 - Todd R <toddrme2178@gmail.com>
- Use openmpi3 for releases that support it.
-------------------------------------------------------------------
Wed Jun 13 16:00:41 UTC 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.
