This typically happens when you have an error in your command line with
mpirun. The most common way to run LAM's mpirun is:

        mpirun C your_application_name

where "C" means "run on all the CPUs specified in the hostfile that you
lambooted with". If you didn't specify CPU counts in the hostfile, 1 is
assumed for each host.

Alternatively, you can do:

        mpirun -np 4 your_application_name

which would start 4 copies of your_application_name. See the man page for
mpirun(1) for more details on all of mpirun's command line options.
