1.2. Organization of this Document

This document is organized as follows:


The rest of this document contains the MPI-2 Standard Specification. It adds substantial new types of functionality to MPI, in most cases specifying functions for an extended computational model (e.g., dynamic process creation and one-sided communication) or for a significant new capability (e.g., parallel I/O).

The following is a list of the chapters in MPI-2, along with a brief description of each.


The Appendices are:


The MPI Function Index is a simple index showing the location of the precise definition of each MPI-2 function, together with C, C++, and Fortran bindings.

MPI-2 provides various interfaces to facilitate interoperability of distinct MPI implementations. Among these are the canonical data representation for MPI I/O and for MPI_PACK_EXTERNAL and MPI_UNPACK_EXTERNAL. The definition of an actual binding of these interfaces that will enable interoperability is outside the scope of this document.

A separate document consists of ideas that were discussed in the MPI Forum and deemed to have value, but are not included in the MPI Standard. They are part of the ``Journal of Development'' (JOD), lest good ideas be lost and in order to provide a starting point for further work. The chapters in the JOD are
