MPI for Python

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

Features

This package supports:

  • Convenient communication of any picklable Python object
    • point-to-point (send & receive)
    • collective (broadcast, scatter & gather, reductions)
  • Fast communication of Python object exposing the Python buffer interface (NumPy arrays, builtin bytes/string/array objects)
    • point-to-point (blocking/nonblocking/persistent send & receive)
    • collective (broadcast, block/vector scatter & gather, reductions)
  • Process groups and communication domains
    • Creation of new intra/inter communicators
    • Cartesian & graph topologies
  • Parallel input/output:
    • read & write
    • blocking/nonblocking & collective/noncollective
    • individual/shared file pointers & explicit offset
  • Dynamic process management
    • spawn & spawn multiple
    • accept/connect
    • name publishing & lookup
  • One-sided operations
    • remote memory access (put, get, accumulate)
    • passive target synchronization (start/complete & post/wait)
    • active target synchronization (lock & unlock)

Install

See INSTALL.rst.
