mpi4py 1.3

MPI for Python

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
