Following the "Example of NWChem RPM installation under CentOS 7", I can successfully run "nwchem_openmpi n2.nw" after doing "module load mpi/openmpi-x86_64". 
Now, how does one request more than one processor?    "nwchem_openmpi -np 4 n2.nw"  returns the error message, There is an error in the input file.
