NAME
       MPI -  Introduction to the Message-Passing Interface

DESCRIPTION
       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.

GETTING STARTED
       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 .

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

       Man pages exist for every MPI subroutine and function.  The  man	 pages
       are also available on the Web at http://www.mcs.anl.gov/mpi/www .

       Additional      on-line	    information	     is	     available	    at
       http://www.mcs.anl.gov/mpi , including a hypertext version of the stan‐
       dard,  information  on  other  libraries	 that use MPI, and pointers to
       other MPI resources.
