Gaussian 16w

By default, Windows may spread threads across all cores, including hyperthreads. For Gaussian, physical cores are better than logical (HT). Use Windows PowerShell to set affinity: start /affinity FFF g16w job.com job.log (FFF = mask for first 12 physical cores).

Gaussian 16W offers the full breadth of Gaussian’s quantum-chemical functionality on Windows platforms, enabling routine and advanced electronic-structure calculations. It is a robust choice for researchers who need proven methods and diverse capabilities, but users should weigh licensing costs, computational demands, and alternatives when planning projects. Sound methodological choices, convergence testing, and benchmarking remain essential to obtain reliable, interpretable results. gaussian 16w

Gaussian 16W includes an extensive internal library of basis sets, ranging from minimal sets (STO-3G) to correlation-consistent basis sets (cc-pVQZ). It supports Effective Core Potentials (ECPs) like LANL2DZ and SDD for heavy elements where relativistic effects become significant. By default, Windows may spread threads across all
