A minimum of 2 GB per core is recommended. High-level calculations like CCSD(T) or large DFT grids require significantly more.

Gaussian 16 is the industry standard for computational chemistry, offering powerful tools for modeling molecular structures, chemical reactions, and spectroscopic properties. While the software provides unparalleled predictive capabilities, deploying it effectively on Linux requires a solid understanding of system architecture, environment variables, and parallel processing frameworks.

In professional research settings, Gaussian 16 on Linux is almost always paired with a job scheduler like Slurm, PBS, or LSF. This integration is vital for fair resource sharing in multi-user environments. Researchers can submit "input files" (.com or .gjf) to a queue, specifying the required RAM and CPU count. The Linux kernel’s superior memory handling ensures that the "out-of-core" instructions—where Gaussian writes temporary data to disk (scratch space)—are handled with minimal latency, provided the GAUSS_SCRDIR is pointed to a fast SSD or NVMe drive.
