You should now be able to successfully compile and execute MPI programs, check the status of your MPI processes, and halt MPI programs that have gone astray. This section gives an overview of the basics of parallel programming with MPI. For a more in-depth discussion of basic and advanced constructs, see the references or look at the man pages by typing man MPI or man MPI_Routinename. Note that you must capitalize MPI for the man pages to work. Also, the MPI routines must be capitalized exactly as they are used in your C programs.
