Bump mpi4py from 3.0.3 to 3.1.1

[dependabot]

Bumps mpi4py from 3.0.3 to 3.1.1.

Release notes

Sourced from mpi4py's releases.

3.1.1

WARNING: This is the last release supporting Python 2.

• Fix typo in Requires-Python package metadata.

• Regenerate C sources with Cython 0.29.24.

3.1.0

WARNING: This is the last release supporting Python 2.

• New features:

  • mpi4py.util: New package collecting miscellaneous utilities.

• Enhancements:

  • Add pickle-based Request.waitsome() and Request.testsome().

  • Add lowercase methods Request.get_status() and Request.cancel().

  • Support for passing Python GPU arrays compliant with the DLPack_ data interchange mechanism (link) and the __cuda_array_interface__ (CAI) standard (link) to uppercase methods. This support requires that mpi4py is built against CUDA-aware MPI implementations. This feature is currently experimental and subject to future changes.

  • mpi4py.futures: Add support for initializers and canceling futures at shutdown. Environment variables names now follow the pattern MPI4PY_FUTURES_*, the previous MPI4PY_* names are deprecated.

  • Add type annotations to Cython code. The first line of the docstring of functions and methods displays a signature including type annotations.

  • Add companion stub files to support type checkers.

  • Support for weak references.

• Miscellaneous:

  • Add a new mpi4py publication (link) to the citation listing.
