If you suspect a hang then you can use the command orte-ps (on the node
where the mpirun is running) and it should show you your job. This will
tell you if the job is started and still running or if there was a
problem launching.

If the program did start and has really hung then you can get more
in-depth information about it using padb which is linked to in my
signature.
