Can someone tell me how to run multiple processes on a node?

I tried 'mpirun -np 4 --map n0-1 ./x' but it didn't work - just run
on all 4 nodes.

Also, I get this output from the command 'mpirun -np 4 --map n0 ./x':

mpirun could not find the executable "3".
Please check your PATH and ensure that the executable is able to be
found and executed.

Looks like something is going wrong with the argument processing.
Thanks,
Greg
