This section will provide an introduction to a simple MPI program,
Hello, world . It will provide
a visual image to relate to and refer back to if you have questions concerning things
like
- what order should these calls be made in?
- what did that parameter list look like?
The program itself is nothing more than the venerable Hello, world
program, so we don't have to be concerned about understanding the purpose or the
algorithm -- rather, we can focus completely on the mechanics of accomplishing an
extremely easy task in parallel.
