mpi4py 0.4.0rc4

MPI for Python

This package provides MPI support for Python scripting in parallel environments. It is constructed on top of the MPI-1/MPI-2 specification, but provides an object oriented interface which closely follows MPI-2 C++ bindings.

This module supports point-to-point (sends, receives) and collective (broadcasts, scatters, gathers, reductions) communications of any picklable Python object.

For objects exporting single-segment buffer interface (strings, NumPy arrays, etc.), blocking/nonbloking/persistent point-to-point, collective and one-sided (put, get, accumulate) communications are fully supported, as well as parallel I/O (blocking and nonbloking, collective and noncollective read and write operatios using explicit file offsets, individual file pointers and shared file pointers).

There is also full support for group and communicator (inter, intra, cartesian and graph topologies) creation and management, as well as any native or user-defined datatypes.
