MPI for Python

Project description

This package provides Python bindings for the Message Passing Interface (MPI) standard. It is implemented on top of the MPI-1/MPI-2 specification and exposes an API which grounds on the standard MPI-2 C++ bindings.

This package supports:

  • Convenient communication of any picklable Python object

    • point-to-point (send & receive)

    • collective (broadcast, scatter & gather, reduction)

  • Fast 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, reduction)

  • 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 (put, get, accumulate)

You can install the in-development version of mpi4py with:

$ pip install mpi4py==dev

or:

$ easy_install mpi4py==dev
