Note: the keywords selected are reprinted on the top of the Calculation Setup window, for example the basis set was changed from 3-21g to 6-31g(d). Please note below the selections on the Job Type and Methods tabs. We will need to make selection in the following tabs: 1) Title, 2) Job Type – Opt+Freq/Minimum/Compute Raman, 3) Method- Ground State/DFT/B3LYP/6-31G(d) and 4) Link 0 – memory and number of CPUs. The Gaussian Calculation Setup window will appear. Open Calculation setup window: Calculate -> Gaussian Calculation Setup. The calculation will be completed very fast. GaussView will run a classical mechanics minimization of the prepared structure. Select Carbon Tetrahedral and click on of the hydrogen atom to make toluene.ģ.4 Use Minimization routine to quickly improve geometry: click the Clean button (the broom icon). Note the Builder Fragment button also displays "benzene." Click anywhere in the New window and benzene will be added:ģ.3 Click on the Element button on the Builder panel and Element Fragments palette will be shown. Select benzene and it appears in the Main window. GaussView will remember to keep it open next time.ģ.1 Start new molecule from the Main window: File -> New -> Create Molecule Groupģ.2 In the Builder window click the ring button - the Ring Fragments window will appear:

Initially two windows of GaussView will be displayed.

Set up your session to use Gaussian. You will have to repeat each time you connect to Lop: > module load gaussian/g16 Go to the newly made directory: > cd gaussian-gv-tutorial Make a new directory for this tutorial: > mkdir gaussian-gv-tutorial Learn more about allocating memory for Slurm jobs.Note: For x-forwarding information see SCS ClustersĬonnect to the SCS cluster (note when working outside of the University network, on need to start a VPN first): If you are running on Della then see the Della section above. This calculation will run for about 25 minutes using 8 CPU-cores. Launch a Gaussian test job by running the following commands: To run Gaussian on Della one must first get a faculty-sponsored account and then put in a separate request to use the software. To submit the job use the following command: For instance, if you are using ntasks=8 and mem=40G then in your input file (e.g., ):

The Gaussian user manual is also a valuable resource.īe sure to sync your Slurm script with the header of the input file.

Avogadro is recommended for new users of Gaussian.

This tutorial shows how to build input files using the Avogadro GUI, which is free. In the Slurm script above,  is the Gaussian input file. You also need to specify how much memory is required. On Adroit there are 32 CPU-cores per node and on Della there are between 28 and 32 (since the older Intel Ivy Bridge nodes cannot be used). Use the snodes command for more info.

The Slurm script should always use -nodes=1 for all Gaussian jobs since our license does not support multi-node (Linda) calculations. Be sure to choose a conservative value of since as increases the queue time increases and the parallel efficiency decreases. The number of CPU-cores is set by your choice of. #SBATCH -mail-type=end # send email when job ends #SBATCH -mail-type=begin # send email when job begins #SBATCH -time=01:00:00 # total run time limit (HH:MM:SS) #SBATCH -mem=40G # total memory per node (4G per cpu-core is default) #SBATCH -cpus-per-task=1 # cpu-cores per task (>1 if multi-threaded tasks) #SBATCH -ntasks= # total number of tasks across all nodes #SBATCH -job-name=gaussian # create a short name for your job Follow the steps above to resolve this.Īll Gaussian calculations on Adroit and Della must be submitted through the job scheduler. Below is a sample Slurm script for a Gaussian 16 job on Adroit: If you do not see these modules then you have not been added to the g03 Linux group. A request will be made to Research Computing to make Gaussian available to you on Adroit (or in some cases Della).Īfter you have access, to see the available modules run these commands: Sign and return the confidentially agreement. You will need to complete a confidentially agreement.
