Gaussian Job Scripts

The following is a sample bash job submission script. It loads "gaussian" module, which detects the CPU type of the machine on which your job runs and chooses the appropriate version of Gaussian for best performance. If OMP_NUM_THREADS is set, Gaussian will use it for the number of processors unless %nproc or %nprocshared is set in your Gaussian input file.

The number of threads specified to Gaussian via either method above must be consistent with the number of processors in your resource request i.e (nodes=1:ppn=N).
