You might want to also check that your "mb" MPI application was
compiled with the Open MPI wrapper compilers (not LAM's wrapper

Additionally, if no one is using LAM/MPI, you might want to remove
it. If LAM was installed by default on your system by the OS, you can
probably use your OS's package management system (rpm, yum, whatever)
to remove LAM.
