mpi4py 1.3

MPI for Python

Package Documentation

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
