		                        This is not a build issue as far as I can see. It is the mpiexec command that starts the 16 nwchem processes on one node, nwchem itself has nothing to do with that. You may want to look at the mpiexec manual. For example adding "-npernode 8" might give you want you need. Alternatively, you may want to use mpirun.

\#!/bin/bash 
\#PBS -N nwchem 
\#PBS -l select=2:ncpus=8:mpiprocs=8:mem=8gb,walltime=00:30:00 
\#PBS -j oe 
 
mpiexec -n 16 nwchem formaldehyde.scf.nwchem > formaldehyde.scf.out
