Visit the LAM-MPI site for more information and tutorials

A typical Beowulf session looks like this:

1. login to the system as lamuser
2. cd to your personal or project directory
3. use your favorite editor to develop code in C, C++, or FORTRAN
4. compile your code using mpicc, mpif77, or mpiCC (see below)
5. when your code is ready to execute, start the LAM parallel environment with the lamstart command.
   note: lamstart is needed only once per session; you don't need to lamstart before every mpirun.
6. run your program using the mpirun command (see below)
7. when you're finished, use the wipe command to shut down the parallel environment.
8. log off.
