From the Preface:
, the Message Passing Interface
, is a standardized and portable message-passing system designed by a group of researchers from academia and industry to function on a wide variety of parallel computers. The standard defines the syntax and semantics of a core of library routines useful to a wide range of users writing portable message-passing programs in Fortran 77 or C. Several well-tested and efficient implementations of MPI already exist, including some that are free and in the public domain. These are beginning to foster the development of a parallel software industry, and there is excitement among computing researchers and vendors that the development of portable and scalable, large-scale parallel applications is now feasible.
The MPI standardization effort involved over 80 people
from 40 organizations, mainly from the United States and Europe. Most of the major vendors of concurrent computers at the time were involved in MPI, along with researchers from universities, government laboratories, and industry.
This book serves as an annotated reference manual for MPI
, and a complete specification of the standard is presented. We repeat the material already published in the MPI specification document , though an attempt to clarify has been made. The annotations mainly take the form of explaining why certain design choices were made, how users are meant to use the interface, and how MPI implementors should construct a version of MPI. Many detailed, illustrative programming examples are also given, with an eye toward illuminating the more advanced or subtle features of MPI.
The complete interface is presented in this book, and we are not hesitant to explain even the most esoteric features or consequences of the standard. As such, this volume does not work as a gentle introduction to MPI, nor as a tutorial. For such purposes, we recommend the companion volume in this series by William Gropp
, Ewing Lusk, and Anthony Skjellum
, Using MPI: Portable Parallel Programming with the Message-Passing Interface
. The parallel application developer will want to have copies of both books handy.
