MPI stands for Message Passing Interface. , simply
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 )Compute pi to a given resolution on 8 processors or threads
% mpiexec -n 8 /usr/local/mpi/examples/cpi
You can compile and link your own MPI programs with the commands mpicc, mpif77, and mpicxx:
% mpicc -o cpi cpi.c % mpif77 -o fpi fpi.f % mpicxx -o cxxpi cxxpi.cxx
Postscript documentation can be found in directory /usr/local/mpi/doc/. These include an introductory guide (guide.ps) and a user manual (manual.ps).
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 standard, information on other libraries that use MPI, and pointers to other MPI resources.
