-8 as in 27az-8, 27bz-8 or 27cz-8.

I had thought that you were starting your jobs by doing:
NP=4 ./a.out
in which case you'd do:
NP=4 NO_LOCAL=1 ./a.out

(you can replace '4' with however many processes you actually want)

As you're using mpirun, you can also do:
mpirun -np "number of processes" -nolocal ./a.out
