A minimum of 2 GB per core is required, though 4 GB or more per core is recommended for large DFT or post-Hartree-Fock (e.g., MP2, CCSD) calculations. The method and basis set (e
The Gaussian input file ( test.com ) remains platform-agnostic, but the submission method differs drastically on Linux.

Gaussian 16 (G16) is a flagship computational chemistry software for modeling electronic structures, molecular geometries, reaction pathways, and spectroscopic properties across gas and solution phases. While the program runs on multiple platforms, Linux remains the preferred environment for serious research thanks to its performance, stability, and seamless integration into high-performance computing clusters. This comprehensive article walks you through everything you need to know to install, configure, run, and optimize Gaussian 16 on Linux—from a single workstation to large-scale HPC deployments.
Always set GAUSS_SCRDIR to a ( /scratch , $SLURM_TMPDIR , /lscratch , or dedicated NVMe drives) rather than a networked home directory. Using a slow network filesystem can drastically increase I/O wait and extend wall‑clock times. Standard C libraries ( glibc ) and compatible

Before diving into the installation, ensure your Linux distribution is compatible. Gaussian 16 is officially supported on: 7, 8, and 9 CentOS/AlmaLinux/Rocky Linux SUSE Linux Enterprise Ubuntu (64-bit LTS versions) Hardware Considerations:
Fast scratch space is critical. Solid-State Drives (SSDs) or Non-Volatile Memory Express (NVMe) drives configured in RAID arrays are highly recommended to handle heavy read/write operations during integral transformations. Software Dependencies
