This script divides a 128-core node into 4 independent jobs, each using 32 cores on its own dedicated partition.

Allocate at least 2 GB to 4 GB of RAM per CPU core for standard Density Functional Theory (DFT) calculations. For post-Hartree-Fock methods (e.g., MP2, CCSD(T)), scale this up to 8 GB–16 GB per core.

Gaussian 16 on Linux represents the intersection of advanced chemical theory and high-tier systems engineering. For the computational chemist, the Linux version is not just a preference but a necessity for stability and speed. It provides the raw power required to transform theoretical equations into predictable, visualizable chemical insights. Bash template to help you automate your Gaussian 16 job submissions?

First, decide on an installation directory. A common practice is to install in /usr/local/ . Log in as a user with sudo privileges and create the directory:
