I just tried to issue the following command
jarrett/home/edwardsa>mpirun -np 4 -nolocal pi3
Failed to exec target program: No such file or directory
When I execute
jarrett/home/edwardsa>mpirun -np 4 pi3 -nolocal
The code runs, but ps -x reveals that it is computing on the head node. I
really don't want compute jobs executing on the head node and it seems that
-nolocal has no effect. What are my options?

P. S. Incidentally, -nolocal doesn't appear on the MPI man page
