MPI - Introduction to the Message-Passing Interface


MPI stands for Message Passing Interface. MPI is a specification (like C or Fortran) and there are a number of implementations. The rest of this man page describes the use of the MPICH implementation of MPI.


Add MPI to your path

 % set path = ( $path /usr/local/mpi/bin )

for the csh and tcsh shells, or

 % export path=$path:/usr/local/mpi/bin

for sh , ksh , and bash shells.

Compute pi to a given resolution on 8 processes

 % mpiexec -n 8 /usr/local/mpi/examples/cpi

You can compile and link your own MPI programs with the commands mpicc , mpif77 , mpicxx , and mpif90 :

 % mpicc -o cpi cpi.c
 % mpif77 -o fpi fpi.f
 % mpicxx -o cxxpi cxxpi.cxx
 % mpif790 -o pi3f90 pi3f90.f90

using the source code from /usr/local/mpi/examples .


PDF documentation can be found in directory /usr/local/mpi/doc/ . These include an installation manual ( install.pdf ) and a user's manual ( usermanual.pdf ).

Man pages exist for every MPI subroutine and function. The man pages are also available on the Web at .

Additional on-line information is available at , including a hypertext version of the standard, information on other libraries that use MPI, and pointers to other MPI resources.

M : Ah, non ! J'ai pa envie qu'ils viennent faire dans ma caisse !
P : T'en fais pas... vu ce qu'ils bouffent, ils doivent chier du sable...
