MPI: A Message-Passing Interface Standard - Version 2.2 - Sep.4. 2009

Item Information

This document describes the Message-Passing Interface (MPI) standard, version 2.2.
The MPI standard includes point-to-point message-passing, collective communications, group and communicator concepts, process topologies, environmental management, process creation and management, one-sided communications, extended collective operations, external interfaces, I/O, some miscellaneous topics, and a profiling interface.
Language bindings for C, C++ and Fortran are defined.

Technically, this version of the standard is based on MPI: A Message-Passing Interface Standard, version 2.1, June 23, 2008. The MPI Forum added seven new routines and a number of enhancements and clarifications to the standard.

Historically, the evolution of the standards is from MPI-1.0 (June 1994) to MPI-1.1
(June 12, 1995) to MPI-1.2 (July 18, 1997), with several clarifications and additions and published as part of the MPI-2 document, to MPI-2.0 (July 18, 1997), with new functionality, to MPI-1.3 (May 30, 2008), combining for historical reasons the documents 1.1 and 1.2 and some errata documents to one combined document, and to MPI-2.1 (June 23, 2008), combining the previous documents. This version, MPI-2.2, is based on MPI-2.1 and provides additional clarifications and errata corrections as well as a few enhancements.
