       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(1,5,7) page describes the use of the MPICH implementation of MPI.

       Add MPI to your path
       % set(7,n,1 builtins) 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(1,2) 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(1,8)  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(1,5,7)  pages
       are also available on the Web at .

       Additional      on-line      information      is      available      at , including a hypertext version(1,3,5) of the stan-
       dard,  information  on  other  libraries  that use MPI, and pointers to
       other MPI resources.
