| PackageDescription | This package provides Message Passing Interface 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 the MPI-2 C++ bindings.
This module supports point-to-point (send, receive) and collective
(broadcast, scatter, gather, reduction) 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 non-collective read and write operations 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
creating user-defined datatypes. Additionally, there is almost
complete support for dynamic process creation and management (spawn,
name publishing). |
