Gaussian Job Scripts

The following is a sample bash submission script. It automatically detects the CPU type of the machine on which your job runs and choose the appropriate version of Gaussian for better 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 should be consistent with the number of processors in your resource request.
