OpenMP and OpenMPI are two different things. OpenMP is a way to
automatically (in limited situations) parallelize your code using a
threading model. OpenMPI is an MPI implementation. MPI is a message
passing standard, which usually parallelizes computation on a process
basis.

Apologies ahead of time for any unintended insults, but...
Your "a.out" sounds like it is not truly a parallel code. If you
submit a hello_world program using OpenMPI's mpirun, you will simply
get two copies of "Hello World" printed to the screen.

That's what's supposed to happen, it's how MPI works. Process 0 is the
head or boss process, and the others are slaves, and execute partially
different code even though they're in the same executable. MPI is
multi-process, not multi-thread.
