Gaussian Example Files

Submit File

### For multi: %NProcShared=7 in input file.
### nodes=1:ppn=8 in this file.
### Short Gaussian jobs. One node one processor core.
### Number of nodes=1: Proc core Per Node=1
#PBS -l nodes=1:ppn=8
### Output files. If not specified PBS uses the job name and ID.
#PBS -o PATH_OF_INPUT/pbs.out
#PBS -e PATH_OF_INPUT/pbs.err
### Mail to user
#PBS -m eb
### Queue name

#PBS -q default
### Job name
#PBS -N JobName
### Declare job-non-rerunable
#PBS -r n

time g09 PATH_TO_INPUT/input.com

Submit Files in a Queue

In putty when submitting a job, instead of using

qsub submit.sh

Use

qsub depend=afterany:123456 submit.sh

will make the program calculate the new job after a previous job is finished. (The previous job ID is 123456 in this case.)

Additional Options

    • geom=allcheck

      Use this to restart your calculation from a geometry in the checkpoint file. Omit the title, multiplicity, charge and coordinates from your input file, such as in the following:

      %nprocshared=7
      %chk=PATH_TO_FILE/freq.chk
      #P B3P86/6-31G* sp Pseudo=Read geom=allcheck

    • POP=(NBO,hirshfeld,FULL)

      Add this, or a variant, to perform an NBO analysis, hirshfeld charge analysis and a full population analysis (pop=full is needed to plot orbitals in Molekel).

 

    • GFOLDPRINT

      Add this keyword to include a more verbose output in the computational logfile. Specifically, this causes the printing of the molecules grid data which is necessary for plotting orbitals in Molekel.

 

    • GFPRINT

      This keyword can be used to see how the atoms of your computation are handled with the basis set you have selected. This means you can see the distribution of functions per atom which you have selected. This is a good way to learn the differences between STO, double-zeta, and triple-zeta quality basis sets.
