• NOTE : You should always run your jobs from scratch5

We have two versions of Gaussian 09 installed at CHPC. Here is an example on how to access them:

embele@login01:~/scratch5 $ module avail                   ### list available modules
embele@login01:~/scratch5 $ module add gaussian/g09.A01    ### load g09 version A01 (older) or
embele@login01:~/scratch5 $ module add gaussian/g09.D01    ### load g09 version D01 (new)

#! /bin/sh
#PBS -N molecule.job
#PBS -l select=1:ncpus=12:jobtype=dell,place=free:group=nodetype
#PBS -l walltime=1:00:00
#PBS -q workq
#PBS -m abe
#PBS -o /export/home/username/scratch/gaussian.out
#PBS -e /export/home/username/scratch/gaussian.err
#PBS -M username@email

cd $PBS_O_WORKDIR
source /etc/profile.d/modules.sh
module add gaussian/g09.A01
source /opt/gridware/applications/gaussian/g09/bsd/g09.profile

g09 < molecule.com > molecule.log

module add gaussian/g09.D01

Both examples above use this example of a gaussian input file:
