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.

In the world of computational quantum chemistry, few names carry as much weight—or as much history—as Gaussian. For decades, it has been the benchmark against which other electronic structure programs are measured. With Gaussian 16 (G16), Revision C.01 being the current standard in many academic and industrial circles, the software continues its legacy of delivering high-accuracy results.

Common Pitfalls and Linux-Specific Debugging

Even seasoned users encounter errors unique to the Gaussian 16 Linux ecosystem.

5. Reliability

• Request nodes/cores and set environment variables in job script.
• Set GAUSS_SCRDIR to node-local directory (e.g., $SLURM_TMPDIR or $TMPDIR).
• Export Gaussian environment script or source installation profile in job script.
• Run Gaussian executable (e.g., g16 < input.com > output.log) or use mpirun wrapper for parallel builds per vendor docs. Action: create and version-control job-script templates for each scheduler with placeholders for %mem and %nprocshared, and ensure cleanup of scratch after job completion.

G16 defaults to 800 MB, but real-world jobs often require much more. Use the command in your input file to request higher allocation. Swap Space:
