the way to run a mpi job, depend on your mpi environment (mpich/lampi 
compiler options). You may use mpirun in spite of mpiexec depending on 
the environnement.
A scheduler like pbs is not "necessary" to run mpi job, its goal is to 
use at best the ressource of the cluster when running multiple jobs.
But if you need one, you can have a look there: http://www.openpbs.org/
