Gaussian 16 on Linux: Installation & User Guide

1. Overview

Gaussian 16 is a leading computational chemistry software package for electronic structure modeling. It can perform calculations ranging from molecular mechanics and semi-empirical methods to high-level ab initio (HF, MP2, CCSD) and density functional theory (DFT). The Linux version offers superior performance on workstations, HPC clusters, and cloud instances.

• Error messages like Convergence failure – run noever or Density matrix is not changing require deep knowledge. No built-in diagnostic tool like ORCA’s orca_prop.

Crucial: Always point GAUSS_SCRDIR to a fast, local disk with plenty of space. Computational bottlenecks often stem from slow I/O during integral storage. 3. Running Your First Calculation Gaussian 16 on Linux: Installation & User Guide 1
