This is particularly useful when you want to specify a custom output file name.
Gaussian 16 requires explicit definition of CPU cores and RAM in the input file:
Each user who runs Gaussian must have their environment configured to point to the software and the scratch directory. Add the following lines to your shell configuration file ( ~/.bashrc for bash users): gaussian 16 linux
Gaussian provides a script to set necessary environment variables. Add these lines to your ~/.bashrc or ~/.profile :
SSH communication keys are not authorized between cluster nodes. This is particularly useful when you want to
Minimum 4 GB per core. Complex calculations (e.g., large-scale TD-DFT or coupled-cluster jobs) require significantly more.
sudo chgrp -R gaussianusers /usr/local/g16 Add these lines to your ~/
To run a Gaussian job, you use the g16 command followed by the input file ( .com or .gjf ) and an output file ( .log or .out ): g16 < input.com > output.log & Use code with caution. Understanding the Input File A standard G16 input includes:
#!/bin/bash #SBATCH --job-name=g16_calc #SBATCH --nodes=1 #SBATCH --ntasks-per-node=16 #SBATCH --mem=32GB source /opt/g16/bsd/g16.profile g16 input.com output.log Use code with caution. Submit it using sbatch job.sh . 5. Frequently Asked Questions (FAQ) How do I open GaussView in Linux?
