Editing Parallel Computing (section)

===MPI (internal)===
[http://www.mcs.anl.gov/research/projects/mpi/ MPI] (Message-Passing Interface) is the dominant standard framework for parallel processing on different computer architectures including '''distributed-memory''' systems. Several MPI implementations (such as [http://www.open-mpi.org/ Open MPI] and [http://www.mcs.anl.gov/research/projects/mpich2/ MPICH2]) are available.

An example of compiling a program with <tt>mpicc</tt> and running it under <tt>mpirun</tt> can be found in [http://www.ahay.org/RSF/book/rsf/bash/mpi.html $RSFSRC/book/rsf/bash/mpi/SConstruct].  Note that Madagascar has a requirement that all internally-executing MPI programs must contain string 'mpi' in the program name as it is needed for SCons to switch to a mpi compiler such as mpicc.
