For example: Suppose you want to optimize the geometry of benzene molecule using B3LYP, then your input file can be benzene_opt_ and the corresponding output file benzene_opt_b3lyp.out. com extension for the input file ( com is short for commands) and either.

If you are new to Gaussian, please read the specification of the input file on Gaussian website. Gaussian input file follows a specific syntax.

This script submits your Gaussian job to SLURM to run on the main partitions no need to use the sbatch command explicitly. Create the appropriate input file (and additional supporting files as necessary), then invoke: g09slurm INPUT_ OUTPUT_FILE.txt Our team has prepared a script named g09slurm to launch Gaussian calculations on Turing and Wahab. Any method of connection would work (SSH, Wahab terminal on Open OnDemand, or terminal under RDP). You will need to access to the shell on the login node. Please connect to the cluster using following the instructions here: Getting Started. You can run Gaussian on either the Wahab or Turing cluster. Gaussian calculations are meant to run on the batch system. ¶ Running Gaussian ¶ Connecting to the Cluster
#Gaussian geometry optimization software
Gaussian09 is a software licensed to ODU and can only be used for non-commercial, academic research purposes by ODU community members. It provides state-of-the-art capabilities for electronic structure modeling. Gaussian09 is the latest version available on ODU Wahab and Turing clusters. It has been continuously updated since then. It is released in 1970 by John Pople and his research group at Carnegie-Mellon University as Gaussian 70. Gaussian provides various ab initio and semiempirical quantum chemistry methods as well as molecular mechanics to predict energies, molecular structures, spectroscopic data (NMR, IR, UV, etc) and much more. Gaussian is a suite of computational chemistry programs used by chemists, chemical engineers, biochemists, physicists and other scientists.
